Vaccines

TOPLINE:

A study has found that less than half of US veterans on chronic immunosuppressive medications, and a much lower percentage of those younger than 50 years, received at least one dose of the recombinant zoster vaccine (RZV) by mid-2023; the low rate of herpes zoster vaccination in this immunocompromised group, especially among younger individuals, is concerning.

METHODOLOGY:

• In 2021, the Food and Drug Administration authorized the use of RZV for adults aged 18 years or older on chronic immunosuppressive medications because of their high risk for herpes zoster and its related complications, followed by updated guidance from the Centers for Disease Control and Prevention and American College of Rheumatology in 2021 and 2022, respectively.
• This study aimed to assess the receipt of RZV among veterans receiving immunosuppressive medications within the Veterans Health Administration (VHA) healthcare system before and after the expanded indications in February 2022.
• It included 190,162 veterans who were prescribed one or more immunosuppressive medications for at least 90 days at 130 medical facilities between January 1, 2018, and June 30, 2023.
• A total of 23,295 veterans (12.3%) were younger than 50 years by the end of the study period.
• The outcome measured was the percentage of veterans with one or more doses of RZV documented during the study period.

TAKEAWAY:

• Among veterans aged 50 years or older, 36.2% and 49.8% received an RZV before the expanded indication and by mid-2023, respectively. Even though the rate of vaccination is higher than that observed in the 2021 National Health Interview Survey, significant room for improvement remains.
• Among veterans younger than 50 years, very few (2.8%) received an RZV before the expanded indication, and only 13.4% received it by mid-2023.
• Demographic factors associated with lower odds of vaccination included male sex, African American or unknown race, and nonurban residence (P ≤ .004 for all).
• Those who received targeted synthetic disease-modifying antirheumatic drugs (DMARDs) alone or in combination with other drugs or those who received other vaccines were more likely to receive RZV than those who received conventional synthetic DMARD monotherapy (P < .001 for both).

IN PRACTICE:

“Future work to improve RZV vaccination in patients at high risk should focus on creating informatics tools to identify individuals at high risk and standardizing vaccination guidelines across subspecialties,” the authors wrote.

LIMITATIONS:

This study may not be generalizable to nonveteran populations or countries outside the United States. Limitations also included difficulty with capturing vaccinations not administered within the VHA system, which may have resulted in an underestimation of the percentage of patients vaccinated.

Introduction: The Need for Increased Vigilance About Maternal Immunization

Viruses are becoming increasingly prevalent in our world and the consequences of viral infections are implicated in a growing number of disease states. It is well established that certain cancers are caused by viruses and it is increasingly evident that viral infections can trigger the development of chronic illness. In pregnant women, viruses such as cytomegalovirus can cause infection in utero and lead to long-term impairments for the baby.

Likewise, it appears that the virulence of viruses is increasing, whether it be the respiratory syncytial virus (RSV) in children or the severe acute respiratory syndrome (SARS) coronaviruses in adults. Clearly, our environment is changing, with increases in population growth and urbanization, for instance, and an intensification of climate change and its effects. Viruses are part of this changing background.

Dr. Reece is the former Dean of Medicine & University Executive VP, and The Distinguished University and Endowed Professor & Director of the Center for Advanced Research Training and Innovation (CARTI) at the University of Maryland School of Medicine, as well as senior scientist at the Center for Birth Defects Research.

The alarming decline in maternal immunization rates that occurred in the wake of the COVID-19 pandemic means that, now more than ever, we must fully embrace our responsibility to recommend immunizations in pregnancy and to communicate what is known about their efficacy and safety. Data show that vaccination rates drop when we do not offer vaccines in our offices, so whenever possible, we should administer them as well.

The ob.gyn. is the patient’s most trusted person in pregnancy. When patients decline or express hesitancy about vaccines, it is incumbent upon us to ask why. Oftentimes, we can identify areas in which patients lack knowledge or have misperceptions and we can successfully educate the patient or change their perspective or misunderstanding concerning the importance of vaccination for themselves and their babies. (See Table 1.) We can also successfully address concerns about safety.

Counseling About Influenza and COVID-19 Vaccination

The COVID-19 pandemic took a toll on vaccination interest/receptivity broadly in pregnant and nonpregnant people. Among pregnant individuals, influenza vaccination coverage declined from 71% in the 2019-2020 influenza season to 56% in the 2021-2022 season, according to data from the Centers for Disease Control and Prevention’s Vaccine Safety Datalink.⁴ Coverage for the 2022-2023 and 2023-2024 influenza seasons was even worse: well under 50%.⁵

Fewer pregnant women have received updated COVID-19 vaccines. Only 13% of pregnant persons overall received the updated 2023-2024 COVID-19 booster vaccine (through March 30, 2024), according to the CDC.⁶

Maternal immunization for influenza has been recommended in the United States since 2004 (part of the recommendation that everyone over the age of 6 months receive an annual flu vaccine), and flu vaccines have been given to millions of pregnant women, but the H1N1 pandemic of 2009 reinforced its value as a priority for prenatal care. Most of the women who became severely ill from the H1N1 virus were young and healthy, without co-existing conditions known to increase risk.⁷

It became clearer during the H1N1 pandemic that pregnancy itself — which is associated with physiologic changes such as decreased lung capacity, increased nasal congestion and changes in the immune system – is its own significant risk factor for severe illness from the influenza virus. This increased risk applies to COVID-19 as well.

As COVID-19 has become endemic, with hospitalizations and deaths not reaching the levels of previous surges — and with mask-wearing and other preventive measures having declined — patients understandably have become more complacent. Some patients are vaccine deniers, but in my practice, these patients are a much smaller group than those who believe COVID-19 “is no big deal,” especially if they have had infections recently.

This is why it’s important to actively listen to concerns and to ask patients who decline a vaccination why they are hesitant. Blanket messages about vaccine efficacy and safety are the first step, but individualized, more pointed conversations based on the patient’s personal experiences and beliefs have become increasingly important.

I routinely tell pregnant patients about the risks of COVID-19 and I explain that it has been difficult to predict who will develop severe illness. Sometimes more conversation is needed. For those who are still hesitant or who tell me they feel protected by a recent infection, for instance, I provide more detail on the unique risks of pregnancy — the fact that “pregnancy is different” — and that natural immunity wanes while the protection afforded by immunization is believed to last longer. Many women are also concerned about the safety of the COVID-19 vaccine, so having safety data at your fingertips is helpful. (See Table 2.)

Counseling About RSV Vaccination

Importantly, for the 2024-2025 RSV season, the maternal RSV vaccine (Abrysvo, Pfizer) is recommended only for pregnant women who did not receive the vaccine during the 2023-2024 season. When more research is done and more data are obtained showing how long the immune response persists post vaccination, it may be that the US Food and Drug Administration (FDA) will approve the maternal RSV vaccine for use in every pregnancy.

The later timing of the vaccination recommendation — 32-36 weeks’ gestation — reflects a conservative approach taken by the FDA in response to data from one of the pivotal trials showing a numerical trend toward more preterm deliveries among vaccinated compared with unvaccinated patients. This imbalance in the original trial, which administered the vaccine during 24-36 weeks of gestation, was seen only in low-income countries with no temporal association, however.

In our experience at two Weill Cornell Medical College–associated hospitals we did not see this trend. Our cohort study of almost 3000 pregnant patients who delivered at 32 weeks’ gestation or later found no increased risk of preterm birth among the 35% of patients who received the RSV vaccine during the 2023-2024 RSV season. We also did not see any difference in preeclampsia, in contrast with original trial data that showed a signal for increased risk.¹¹

When fewer than 2 weeks have elapsed between maternal vaccination and delivery, the monoclonal antibody nirsevimab is recommended for the newborn — ideally before the newborn leaves the hospital. Nirsevimab is also recommended for newborns of mothers who decline vaccination or were not candidates (e.g. vaccinated in a previous pregnancy), or when there is concern about the adequacy of the maternal immune response to the vaccine (e.g. in cases of immunosuppression).

While there was a limited supply of the monoclonal antibody last year, limitations are not expected this year, especially after October.

The ultimate goal is that patients choose the vaccine or the immunoglobulin, given the severity of RSV disease. Patient preferences should be considered. However, given that it takes 2 weeks after vaccination for protection to build up, I stress to patients that if they’ve vaccinated themselves, their newborn will leave the hospital with protection. If nirsevimab is relied upon, I explain, their newborn may not be protected for some period of time.
 

Take-home Messages

• When patients decline or are hesitant about vaccines, ask why. Listen actively, and work to correct misperceptions and knowledge gaps.
• Whenever possible, offer vaccines in your practice. Vaccination rates drop when this does not occur.
• COVID-vaccine safety is backed by many studies showing no increase in birth defects, preterm delivery, miscarriage, or stillbirth.
• Pregnant women are more likely to have severe illness from the influenza and SARS-CoV-2 viruses. Vaccines can prevent severe illness and can protect the newborn as well as the mother.
• Recommend/administer the maternal RSV vaccine at 32-36 weeks’ gestation in women who did not receive the vaccine in the 2023-2024 season. If mothers aren’t eligible their babies should be offered nirsevimab.

I routinely tell pregnant patients about the risks of COVID-19 and I explain that it has been difficult to predict who will develop severe illness. Sometimes more conversation is needed. For those who are still hesitant or who tell me they feel protected by a recent infection, for instance, I provide more detail on the unique risks of pregnancy — the fact that “pregnancy is different” — and that natural immunity wanes while the protection afforded by immunization is believed to last longer. Many women are also concerned about the safety of the COVID-19 vaccine, so having safety data at your fingertips is helpful. (See Table 2.)

Counseling About RSV Vaccination

Importantly, for the 2024-2025 RSV season, the maternal RSV vaccine (Abrysvo, Pfizer) is recommended only for pregnant women who did not receive the vaccine during the 2023-2024 season. When more research is done and more data are obtained showing how long the immune response persists post vaccination, it may be that the US Food and Drug Administration (FDA) will approve the maternal RSV vaccine for use in every pregnancy.

The later timing of the vaccination recommendation — 32-36 weeks’ gestation — reflects a conservative approach taken by the FDA in response to data from one of the pivotal trials showing a numerical trend toward more preterm deliveries among vaccinated compared with unvaccinated patients. This imbalance in the original trial, which administered the vaccine during 24-36 weeks of gestation, was seen only in low-income countries with no temporal association, however.

In our experience at two Weill Cornell Medical College–associated hospitals we did not see this trend. Our cohort study of almost 3000 pregnant patients who delivered at 32 weeks’ gestation or later found no increased risk of preterm birth among the 35% of patients who received the RSV vaccine during the 2023-2024 RSV season. We also did not see any difference in preeclampsia, in contrast with original trial data that showed a signal for increased risk.¹¹

When fewer than 2 weeks have elapsed between maternal vaccination and delivery, the monoclonal antibody nirsevimab is recommended for the newborn — ideally before the newborn leaves the hospital. Nirsevimab is also recommended for newborns of mothers who decline vaccination or were not candidates (e.g. vaccinated in a previous pregnancy), or when there is concern about the adequacy of the maternal immune response to the vaccine (e.g. in cases of immunosuppression).

While there was a limited supply of the monoclonal antibody last year, limitations are not expected this year, especially after October.

The ultimate goal is that patients choose the vaccine or the immunoglobulin, given the severity of RSV disease. Patient preferences should be considered. However, given that it takes 2 weeks after vaccination for protection to build up, I stress to patients that if they’ve vaccinated themselves, their newborn will leave the hospital with protection. If nirsevimab is relied upon, I explain, their newborn may not be protected for some period of time.
 

Take-home Messages

• When patients decline or are hesitant about vaccines, ask why. Listen actively, and work to correct misperceptions and knowledge gaps.
• Whenever possible, offer vaccines in your practice. Vaccination rates drop when this does not occur.
• COVID-vaccine safety is backed by many studies showing no increase in birth defects, preterm delivery, miscarriage, or stillbirth.
• Pregnant women are more likely to have severe illness from the influenza and SARS-CoV-2 viruses. Vaccines can prevent severe illness and can protect the newborn as well as the mother.
• Recommend/administer the maternal RSV vaccine at 32-36 weeks’ gestation in women who did not receive the vaccine in the 2023-2024 season. If mothers aren’t eligible their babies should be offered nirsevimab.

Acute otitis media (AOM) is caused by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Since the introduction of pneumococcal conjugate vaccines (PCVs) shifts in the proportion of these three bacteria as causes of AOM and their antibiotic susceptibility profiles and strain diversity have occurred due to multiple factors including the PCVs and antibiotic selection pressure.

The 7-valent PCV (PCV7) was introduced in 2000 and was proven to be efficacious in preventing AOM, but no subsequent PCV has received an indication for prevention of AOM because the FDA required a tympanocentesis study to prove efficacy and that approval was not achieved for PCV13, PCV15, or PCV20. This is a little known fact. After introduction of PCV7, replacement pneumococcal strains expressing serotypes not in PCV7 emerged and antibiotic non-susceptible strains became predominant causes of AOM, especially antibiotic-resistant serotype 19A. To address the phenomena of pneumococcal serotype replacement, PCV13 was introduced in 2010. But serotype replacement continued to occur under PCV13 pressure, replacement serotypes increasingly caused AOM, and antibiotic-resistant serotype 35B emerged. Now we have two new higher valency PCVs: PCV15 (Merck) where serotypes 22F and 33F were added to the PCV13 serotypes and PCV20 (Pfizer) where 22F, 33F, 8, 10A, 11A, 12F, 15B were added to PCV13. Note that neither PCV15 nor PCV20 includes the most common serotype causing AOM – serotype 35B.¹

While PCV15 and PCV20 should provide protection against more pneumococcal serotypes, increasing serotypes in both vaccines decreased immunogenicity of certain shared serotypes, more so with the addition of seven more in PCV20 than two more in PCV15, compared with PCV13. Whether lower antibody concentrations will make a difference clinically in terms of vaccine failure to prevent nasopharyngeal colonization, AOM, and/or invasive pneumococcal infections is currently unknown.

Our group from greater Rochester, New York, is the only one in the United States performing tympanocentesis to determine the etiology of AOM infections. Children between ages 6 and 36 months are studied. We recently reported our results for the time span September 2021 to September 2023, the immediate 2 years prior to recommendations for use of PCV15 and PCV20 in young children.² Tympanocentesis was performed in 139 (78%) of 179 episodes of AOM, yielding 216 middle ear fluid samples (the higher number of middle ear fluids was due to bilateral tympanocentesis in some children). H. influenzae (40%) was the most common bacterial isolate, followed by S. pneumonia (19%) and M. catarrhalis (17%), with the remainder no growth. Polymerase chain reactions (PCR) was positive in many of those culture negative samples, suggesting prior use of antibiotics before tympanocentesis was performed. Among the pneumococcal isolates, 46% were oxacillin non-susceptible. Among the H. influenzae isolates, 27% were beta-lactamase producing and all M. catarrhalis were beta-lactamase-producing.

As we previously reported,¹ we once again found that serotype 35B was the most frequent non-PCV15, non-PCV20, serotype. Other frequently detected non-PCV20 pneumococcal serotypes were 23A, 23B, 35D, 35F and 15C.²
 

Projected Pneumococcal Serotype Coverage by PCV15 and PCV20

PCV13 serotypes were identified in 9% of middle ear fluids, consistent with vaccine failure. As we commence use of PCV15 and PCV20 in the United States, our data provide insights regarding estimation of the projected effects of these vaccines on AOM. Assuming 100% vaccine-type effectiveness, PCV15 will provide about 11% coverage of pneumococci causing AOM, the same PCV13 and PCV20 will provide 30% coverage, leaving 70% of pneumococci causing AOM in young children uncovered (Figure).

When Kimberly Fisher, MD, was a junior doctor, she got fired up when patients showed hesitancy about vaccines. She responded by providing numbers, data, and facts that proved vaccines were safe and effective in preventing life-threatening diseases. But she soon realized that regurgitating scientific evidence wasn’t a winning strategy. “I’ve made the mistake of launching into a let me tell you all the things that I know that you don’t know kind of lecture,” Dr. Fisher, now an associate professor of medicine at UMass Chan Medical School, Worcester, Massachusetts, a pulmonary physician, and a researcher interested in patient-provider communication, told this news organization. “Through experience and research, I have learned that when you do that, they stop listening.”

She said when patients give reasons for not getting vaccinated that are factually wrong and rooted in misinformation, the most common reaction is to correct that information and not let it stand. “That is important; it just can’t be the first thing you do,” she said.

Diane Arnaout, MD, a pediatrician at Cook Children’s Pediatrics in Fort Worth, Texas, said listening to some patients explaining why vaccine injections are poisonous or a conspiracy can be exhausting and frustrating, but she agrees that presenting scientific facts alone won’t change people’s minds. “Even in my worst days, I take the time to stop talking for a moment and let the parents talk about what concerns them because if you just get mad and put a wall up, then that trust is gone, possibly forever, not just about vaccines.”
 

The Default Option

Since the start of the COVID-19 pandemic, Dr. Fisher has dedicated much of her time researching vaccine hesitancy. One of the most “fascinating and unexpected” findings of her work was that people are more likely to get vaccinated if a healthcare provider recommends that they get vaccinated in a “presumptive style,” which means that the provider uses language that presupposes that the person’s going to get vaccinated. “Rather than asking whether they wanted to get the vaccine conveying that the option of not getting it is just as valid, you make vaccination the default option,” she suggested.

The strategy wins many undecided, but it might not work on the most reluctant. “The presumptive recommendation is very directive, and if that works, great, but if it doesn’t, you need to shift to almost the opposite strategy, showing empathy and understanding about the person’s reasons for not wanting to be vaccinated,” Dr. Fisher said.
 

Find One Thing to Agree On

During a focus group on COVID-19 vaccine hesitancy that Dr. Fisher conducted in December 2021, most physicians expressed frustration that some patients remained resistant despite their best efforts. However, one participant shared an approach she found effective with even the most hesitant patients. The physician would listen carefully and express understanding, and even if what the patient said wasn’t accurate, she would find a kernel of truth to agree with and align herself with the patient. By doing this, she made patients feel like they were a team.

The example she gave was if a patient said, “I don’t know. I’ve heard different things and don’t feel comfortable taking the vaccine,” she might respond with something like, “I think it’s great that you’re thinking critically about this before making a decision. I was the same way — I wanted to fully understand the data before getting vaccinated. I also wouldn’t want to take something if I thought it wasn’t safe. It’s good that you’re being thorough.” Acknowledging their careful thought process, the physician helped patients feel seen and understood only after she introduced additional information to guide them toward understanding why the vaccine might be beneficial.
 

Focus on the Disease

Dr. Arnaout’s frustration grows when at the end of an appointment some parents object to vaccines with irrational and misguided concerns. “You’ve trusted me with everything else we’ve discussed today — whether it’s a diaper rash or an ear infection — so why wouldn’t you trust me on this? Sometimes it feels almost offensive — why trust my medical expertise on everything else but not vaccines?” she said.

The answer, she believes, is that vaccines are preventive, and when the threat of disease feels distant, it’s hard to see the necessity of a painful shot for your healthy child. “But if your baby were dying from meningitis, the needles we use to deliver life-saving medications in the hospital would feel absolutely necessary. It’s hard as a parent to inflict pain for something you’ve never personally seen.”

Dr. Arnaout thinks it is important to bring the focus on the disease the vaccine prevents. “Let’s talk about measles — how if a baby in my waiting room has measles and coughs, the virus can stay suspended in the air for 2 hours, and 100% of unvaccinated people in that room will get measles.”

She said sharing personal stories can also help physicians connect with their patients. “I talk to parents every day about their vaccine concerns, and I’ve found that if I take the time to explain why we vaccinate, they start to understand. I also tell them, ‘I vaccinated my children for everything on time and give them the flu shot every year. Why would I offer your child something I wouldn’t give my own?’ That personal decision, made without hesitation, resonates with parents.”
 

Wired for Stories

Medical professionals have a professional necessity to think and speak with precision. Their training is based on analyzing studies and data, and they develop a specialized vocabulary to describe their findings accurately.

But the human brain is naturally inclined to process and make sense of information through the structure and narrative of stories. We instinctively organize reality into a “shape of a story” rather than just isolated facts, explained Ben Riggs, senior communications specialist at Kettering Health, Dayton, Ohio, a nonfiction writing coach and author. Storytelling also taps into the emotional, rather than just the rational, parts of the brain. This emotional connection helps make the information more memorable and impactful for the listener.

Mr. Riggs said that moving from this world of precision and accuracy to one that also requires effective communication with those who haven’t had that same training is much like learning a new language. “If they can’t speak in a way that non-scientists understand, it’s like the old saying: If a tree falls in the woods and no one hears it, does it make a sound?”

Metaphors can help doctors translate scientific facts into language that meets people where they are, allowing patients to make informed decisions about their health. They can help physicians transform abstract concepts into vivid, tangible mental images that are easier for people to understand and relate to, Mr. Riggs explained. “We are predominantly concrete thinkers. Metaphors can create concrete scenes and do much of the heavy lifting when communicating complex ideas.”

“It’s important to align yourself with the other person by showing that you care, that you’re truly listening, and understand their perspective,” concluded Dr. Fisher. “Acknowledge their point of view and emphasize that they have autonomy in the decision-making process. This can open people up to hearing your perspective. You also need to know when to let go don’t cause a rift in the relationship.”

Dr. Fisher, Dr. Arnaout, and Mr. Riggs reported no relevant financial relationships.

However, one participant shared an approach she found effective with even the most hesitant patients. The physician would listen carefully and express understanding, and even if what the patient said wasn’t accurate, she would find a kernel of truth to agree with and align herself with the patient. By doing this, she made patients feel like they were a team.

The example she gave was if a patient said, “I don’t know. I’ve heard different things and don’t feel comfortable taking the vaccine,” she might respond with something like, “I think it’s great that you’re thinking critically about this before making a decision. I was the same way — I wanted to fully understand the data before getting vaccinated. I also wouldn’t want to take something if I thought it wasn’t safe. It’s good that you’re being thorough.” Acknowledging their careful thought process, the physician helped patients feel seen and understood only after she introduced additional information to guide them toward understanding why the vaccine might be beneficial.
 

Focus on the Disease

Dr. Arnaout’s frustration grows when at the end of an appointment some parents object to vaccines with irrational and misguided concerns. “You’ve trusted me with everything else we’ve discussed today — whether it’s a diaper rash or an ear infection — so why wouldn’t you trust me on this? Sometimes it feels almost offensive — why trust my medical expertise on everything else but not vaccines?” she said.

The answer, she believes, is that vaccines are preventive, and when the threat of disease feels distant, it’s hard to see the necessity of a painful shot for your healthy child. “But if your baby were dying from meningitis, the needles we use to deliver life-saving medications in the hospital would feel absolutely necessary. It’s hard as a parent to inflict pain for something you’ve never personally seen.”

Dr. Arnaout thinks it is important to bring the focus on the disease the vaccine prevents. “Let’s talk about measles — how if a baby in my waiting room has measles and coughs, the virus can stay suspended in the air for 2 hours, and 100% of unvaccinated people in that room will get measles.”

She said sharing personal stories can also help physicians connect with their patients. “I talk to parents every day about their vaccine concerns, and I’ve found that if I take the time to explain why we vaccinate, they start to understand. I also tell them, ‘I vaccinated my children for everything on time and give them the flu shot every year. Why would I offer your child something I wouldn’t give my own?’ That personal decision, made without hesitation, resonates with parents.”
 

Wired for Stories

Medical professionals have a professional necessity to think and speak with precision. Their training is based on analyzing studies and data, and they develop a specialized vocabulary to describe their findings accurately.

But the human brain is naturally inclined to process and make sense of information through the structure and narrative of stories. We instinctively organize reality into a “shape of a story” rather than just isolated facts, explained Ben Riggs, senior communications specialist at Kettering Health, Dayton, Ohio, a nonfiction writing coach and author. Storytelling also taps into the emotional, rather than just the rational, parts of the brain. This emotional connection helps make the information more memorable and impactful for the listener.

Mr. Riggs said that moving from this world of precision and accuracy to one that also requires effective communication with those who haven’t had that same training is much like learning a new language. “If they can’t speak in a way that non-scientists understand, it’s like the old saying: If a tree falls in the woods and no one hears it, does it make a sound?”

Metaphors can help doctors translate scientific facts into language that meets people where they are, allowing patients to make informed decisions about their health. They can help physicians transform abstract concepts into vivid, tangible mental images that are easier for people to understand and relate to, Mr. Riggs explained. “We are predominantly concrete thinkers. Metaphors can create concrete scenes and do much of the heavy lifting when communicating complex ideas.”

“It’s important to align yourself with the other person by showing that you care, that you’re truly listening, and understand their perspective,” concluded Dr. Fisher. “Acknowledge their point of view and emphasize that they have autonomy in the decision-making process. This can open people up to hearing your perspective. You also need to know when to let go don’t cause a rift in the relationship.”

Dr. Fisher, Dr. Arnaout, and Mr. Riggs reported no relevant financial relationships.

When Kimberly Fisher, MD, was a junior doctor, she got fired up when patients showed hesitancy about vaccines. She responded by providing numbers, data, and facts that proved vaccines were safe and effective in preventing life-threatening diseases. But she soon realized that regurgitating scientific evidence wasn’t a winning strategy. “I’ve made the mistake of launching into a let me tell you all the things that I know that you don’t know kind of lecture,” Dr. Fisher, now an associate professor of medicine at UMass Chan Medical School, Worcester, Massachusetts, a pulmonary physician, and a researcher interested in patient-provider communication, told this news organization. “Through experience and research, I have learned that when you do that, they stop listening.”

She said when patients give reasons for not getting vaccinated that are factually wrong and rooted in misinformation, the most common reaction is to correct that information and not let it stand. “That is important; it just can’t be the first thing you do,” she said.

Diane Arnaout, MD, a pediatrician at Cook Children’s Pediatrics in Fort Worth, Texas, said listening to some patients explaining why vaccine injections are poisonous or a conspiracy can be exhausting and frustrating, but she agrees that presenting scientific facts alone won’t change people’s minds. “Even in my worst days, I take the time to stop talking for a moment and let the parents talk about what concerns them because if you just get mad and put a wall up, then that trust is gone, possibly forever, not just about vaccines.”
 

The Default Option

Since the start of the COVID-19 pandemic, Dr. Fisher has dedicated much of her time researching vaccine hesitancy. One of the most “fascinating and unexpected” findings of her work was that people are more likely to get vaccinated if a healthcare provider recommends that they get vaccinated in a “presumptive style,” which means that the provider uses language that presupposes that the person’s going to get vaccinated. “Rather than asking whether they wanted to get the vaccine conveying that the option of not getting it is just as valid, you make vaccination the default option,” she suggested.

The strategy wins many undecided, but it might not work on the most reluctant. “The presumptive recommendation is very directive, and if that works, great, but if it doesn’t, you need to shift to almost the opposite strategy, showing empathy and understanding about the person’s reasons for not wanting to be vaccinated,” Dr. Fisher said.

New data from the Centers for Disease Control and Prevention (CDC) show significant spikes in pertussis cases compared with last year, especially in several urban areas including New York, Illinois, Florida, and Colorado. Cases are rising at the same time that rates of vaccination have been on the decline.

Notably, the current pertussis case count in Illinois as of September 21, 2024, was five times higher than the total cases in 2023 (1058 vs 50). New York City alone had reported 624 cases as of September 21, compared with 38 cases in 2023. 

Additional data from the CDC on vaccination coverage and exemptions of school-aged children showed an increase from 3.0% last year to 3.3% in 2024 of children who were exempted from recommended vaccination requirements. Although nearly 93% of kindergarteners in the United States received recommended vaccines (including Tdap), similar to last year, this number shows a steady decline from 94% in the 2021-2021 school year and 93% in the 2021-2022 school year, according to previous CDC reports.
 

What’s Happening in the Clinic

Clinical experience and the most recent CDC data point to under vaccination as a driver of the increased pertussis cases this year, David J. Cennimo, MD, associate professor of medicine and pediatrics in the division of infectious disease at Rutgers New Jersey Medical School, Newark, New Jersey, said in an interview.

Although the pertussis vaccination rates in infancy are still very good, clinicians are seeing a drop-off in school-aged children and adults, and the lingering anti-vaccine efforts from the COVID-19 pandemic period are undoubtedly playing a part, said Dr. Cennimo. “Unfortunately, pertussis is contagious, and the vaccine effectiveness wears off. Having decreased numbers of people protected results in more rapid spread,” he said. 

Dr. Cennimo agreed that the number of cases in the United States is underreported, and even higher than the data suggest. “I’m sure of it; the initial clinical presentation may be mistaken for a viral upper respiratory tract infection (common cold),” he told this news organization.

Many older children and adults with pertussis do not manifest the classic “whooping cough” seen in infants and young children, so making a clinical diagnosis can be difficult, he said. “One classical component of the illness is a prolonged cough. I have wondered if some people now reporting a lingering cough had pertussis that was missed,” Dr. Cennimo noted. 

“Clinicians should stress the value of boosters in a vaccine-preventable illness where we know immunity wanes overtime,” Dr. Cennimo said. “We have a great remedy in the Tdap vaccine, which we should all be getting very 10 years,” he said. 

He also emphasized that clinicians remind pregnant women of the current recommendations to receive the Tdap vaccine for every pregnancy. “Vaccination during pregnancy is the best way to protect both the pregnant person and the newborn. 

Even for the vaccine hesitant, this vaccine has a long track record of safety so should not be a significant concern,” he said.

The ultimate take-home message is not a new one, and applies to all illnesses, Dr. Cennimo told this news organization. Simply put, “Stay home if you are sick. Social distancing is not just for COVID-19,” he said.

Dr. Cennimo had no financial conflicts to disclose.

As primary care physicians, we are often the first ones patients see when they become infected with influenza. According to Centers for Disease Control and Prevention statistics, approximately 5%-20% of the US population will be infected with influenza every year. Additionally, more than 200,000 of these patients will be hospitalized because of complications related to influenza.

Earlier in September, the World Health Organization (WHO) issued its latest clinical practice guidelines for influenza for the 2024-2025 season. This is a 213-page document aimed at healthcare providers who treat patients infected with influenza. It includes treatment for those with severe and nonsevere influenza infections, those in both the outpatient and hospitalized setting, as well as medication prophylaxis for those exposed to the virus. Additionally, it defines risk estimates for those who are at risk of being hospitalized or dying. In contrast, previous updates focused on management of severe influenza or those at risk of severe influenza.

These guidelines cover recommendations regarding all the antiviral medications for treating influenza used around the world. For the purpose of this article, we will focus on those most commonly used in the United States.

A newer medication discussed was baloxavir. It is recommended to be used for patients with nonsevere influenza who are at high risk for progression to severe disease. The advice is to not use it for those with little risk of progression to severe disease. Oseltamivir is recommended for those with severe infection.

The guidelines recommend against using antibiotics for those who have a low likelihood of having a bacterial coinfection. As primary care doctors, we often prescribe medications to help with symptoms. These guidelines recommend against the use of corticosteroids and antibiotics but did advise that NSAIDs could be used for symptom relief.

One of the important parts of these guidelines is prevention in patients who have been exposed but are asymptomatic. They recommend baloxavir or oseltamivir but only for those patients who are at high risk of being hospitalized if they were to become infected. Any of the antivirals can be used for patients who are exposed to the novel influenza A, which is associated with a higher mortality rate. Caution when prescribing antivirals is recommended in immunocompromised patients because there is more drug resistance seen in these patients.

These updates also discuss the use of different influenza tests. In the outpatient setting, primary doctors don’t have time for test results that may take 2 days to come back. Only rapid tests make the sense in the primary care setting. Additionally, in the age of COVID, it is important to make an accurate diagnosis so we should be testing patients. There is resistance seen with the antivirals we prescribe for influenza so prescribing them empirically without a confirmed diagnosis of influenza may be doing more harm than good.

One gap in these recommendations is vaccination. This topic was not covered at all. It would be helpful to have a strategy in place to prevent infection in populations rather than focusing just on exposed individuals. A discussion of when and who and to vaccinate would be helpful. Research into the effectiveness of vaccines is key and more accurate development of a season’s influenza vaccine would be beneficial. Currently, there is much vaccine misinformation being spread around. Education and information regarding influenza vaccines, especially coming from WHO, is crucial.

Another failure of these recommendations is that the guidelines apply only to those who present within a few days of becoming symptomatic. As family doctors, we know many of our patients self-treat or consult Google. They often don’t come for medical care until they’ve been sick for a week or longer. There are no guidelines for these patients.

In general, these guidelines are comprehensive and do a great job discussing the current medications available. However, more is needed to increase vaccination rates. Patients need to know that if they may be sick with influenza, they need to seek medical care as soon as possible. We, as family doctors, need to do a better job of risk-stratifying our patients and prescribing prophylactic medication when suitable. Every infection we prevent aids in the health of our community and the global population at large.

Pertussis cases in the United States have increased fourfold compared with the same time period last year, according to data from the Centers for Disease Control and Prevention (CDC). Reports from several states illustrate this trend, thought to be due to reduced immunity across the country.

The Alaska Department of Health issued a statement on its website about the significant increase in pertussis cases in the state during the summer, with 90 cases in July and 61 in August, compared with 24 in June and a total of 26 cases in 2023.

Similarly, the Florida Department of Health reported a pertussis increase in July 2024 that was higher than the June 2024 case count and also above the previous 5-year average.

Experts in these and other states suggest that several factors are driving the nationwide increase, including the fact that fewer people are consistently wearing masks. The mass masking during the COVID-19 pandemic caused a significant drop in pertussis, but the latest data suggest a return to prepandemic levels, and waning immunity likely plays a role as well.

Pertussis, also known as whooping cough, typically begins with symptoms similar to those of the common cold, including runny nose, sneezing, mild fever, and cough, according to the CDC. However, babies with whooping cough may experience trouble breathing rather than a cough. The coughing fits often associated with pertussis may not start until 2 weeks after the onset of other symptoms, according to the CDC.

Those who have been vaccinated against pertussis can still become infected, but the risk is lower, and the illness, if it occurs, is likely to be milder. Complications such as apnea, pneumonia, and convulsions can occur in babies younger than 1 year, especially if they have not been vaccinated, according to the CDC.
 

Beyond Easing Pandemic Precautions

Many respiratory-based infections dipped during the COVID-19 pandemic, almost certainly from the multifactorial interventions of masking, distancing, and the general lack of comingling, said David J. Cennimo, MD, associate professor of medicine & pediatrics in the Division of Infectious Diseases at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.

The number of cases of many of these diseases returned to previous levels after COVID-19 restrictions were lifted, he said.

“However, we know pertussis immunity wanes over time. Children get DTaP at 2, 4, 6, and 15 months, and a Tdap booster at 11-12 years old gets them to adulthood,” Dr. Cennimo said. Adults should be getting a Tdap every 10 years, he added.

The latest available CDC data indicate that Tdap vaccine coverage in adults is approximately 40%, which means that there may be a large number of susceptible people who can become infected and propagate to others, said Dr. Cennimo.
 

Not Just the Young Ones

A recent pertussis outbreak among college students in Virginia highlighted the fact that the infection can affect all ages, and that the effectiveness of childhood vaccines may decrease over time. The majority of the recently diagnosed cases occurred in individuals who had been previously vaccinated, according to a press release from the Virginia Department of Health.

Clinical Clues

The initial stage of pertussis infection looks like a common cold with symptoms of upper respiratory infection, Dr. Cennimo told this news organization. “Unless there is reason to suspect pertussis exposure, it would almost certainly be missed,” he noted.

The characteristic barking/seal-like cough is mostly seen in children, said Dr. Cennimo. Adults and children can experience coughing fits that can lead to shortness of breath and/or vomiting, which would raise suspicion for pertussis, but is not universally present, he said. The convalescent stage of pertussis can be prolonged and is characterized by chronic coughing. “In the past, pertussis had been called the 100-day cough,” and at that point, treatment is ineffective, Dr. Cennimo said.

In clinical practice, “I advise everyone to get the Tdap vaccine every 10 years,” and remember that the “Td” is the every 10-year tetanus shot as well, Dr. Cennimo told this news organization. Reassure patients that the Tdap can be given with other vaccines, he said, and remind patients that, as with any of the respiratory illnesses, they should stay home if sick, cover a cough, consider wearing a mask in public, and wash hands frequently, he said. 

Dr. Cennimo had no financial conflicts to disclose.

Pertussis cases in the United States have increased fourfold compared with the same time period last year, according to data from the Centers for Disease Control and Prevention (CDC). Reports from several states illustrate this trend, thought to be due to reduced immunity across the country.

The Alaska Department of Health issued a statement on its website about the significant increase in pertussis cases in the state during the summer, with 90 cases in July and 61 in August, compared with 24 in June and a total of 26 cases in 2023.

Similarly, the Florida Department of Health reported a pertussis increase in July 2024 that was higher than the June 2024 case count and also above the previous 5-year average.

Experts in these and other states suggest that several factors are driving the nationwide increase, including the fact that fewer people are consistently wearing masks. The mass masking during the COVID-19 pandemic caused a significant drop in pertussis, but the latest data suggest a return to prepandemic levels, and waning immunity likely plays a role as well.

New COVID-19 vaccines formulated for better protection against the currently circulating variants have been approved by the US Food and Drug Administration.

The COVID vaccines available this fall have been updated to better match the currently circulating COVID strains, said William Schaffner, MD, professor of medicine in the Division of Infectious Diseases at Vanderbilt University, Nashville, Tennessee, in an interview.

“The Pfizer and Moderna vaccines — both mRNA vaccines — target the KP.2 variant, while the Novavax vaccine targets the JN.1 variant, which is a predecessor to KP.2,” said Dr. Schaffner, who also serves as a spokesperson for the National Foundation for Infectious Diseases. “The Novavax vaccine is a protein adjuvant vaccine made in a more traditional fashion and may appeal to those who remain hesitant about receiving an mRNA vaccine,” he explained. However, all three vaccines are designed to protect against severe COVID illness and reduce the likelihood of hospitalization, he said.
 

Who Needs It?

“The CDC’s Advisory Committee on Immunization Practices (ACIP) continues to recommend that everyone in the United States who is age 6 months and older receive the updated COVID vaccine this fall, along with influenza vaccine,” Dr. Schaffner said.

“This was not a surprise because COVID will produce a sizable winter outbreak,” he predicted. Although older people and those who have chronic medical conditions such as heart or lung disease, diabetes, or other immunocompromising conditions suffer the most serious impact of COVID, he said. “The virus can strike anyone, even the young and healthy.” The risk for long COVID persists as well, he pointed out.

The ACIP recommendation is endorsed by the American Academy of Pediatrics and other professional organizations, Dr. Shaffner said.

A frequently asked question is whether the COVID and flu vaccines can be given at the same time, and the answer is yes, according to a statement from the Centers for Disease Control and Prevention (CDC).

“The optimal time to be vaccinated is late September and anytime during October in order to get the benefit of protection through the winter,” Dr. Schaffner said.

As with earlier versions of the COVID-19 vaccine, side effects vary from person to person. Reported side effects of the updated vaccine are similar to those seen with earlier versions and may include injection site pain, redness and swelling, fatigue, headache, muscle pain, chills, nausea, and fever, but most of these are short-lived, according to the CDC.
 

Clinical Guidance

The CDC’s clinical guidance for COVID-19 vaccination outlines more specific guidance for vaccination based on age, vaccination history, and immunocompromised status and will be updated as needed.

A notable difference in the latest guidance is the recommendation of only one shot for adults aged 65 years and older who are NOT moderately or severely immunocompromised. For those who are moderately or severely immunocompromised, the CDC recommends two to three doses of the same brand of vaccine.

Dr. Schaffner strongly encouraged clinicians to recommend the COVID-19 vaccination for all eligible patients. “COVID is a nasty virus that can cause serious disease in anyone,” and protection from previous vaccination or prior infection has likely waned, he said.

Dr. Schaffner also encouraged healthcare professionals and their families to lead by example. “We should all be vaccinated and let our patients know that we are vaccinated and that we want all our patents to be protected,” he said.

The updated COVID-19 vaccination recommendations have become much simpler for clinicians and patients, with a single messenger RNA (mRNA) vaccine required for anyone older than 5 years, said David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.

“The recommendations are a bit more complex for children under 5 years old receiving their first vaccination; they require two to three doses depending on the brand,” he said. “It is important to review the latest recommendations to plan the doses with the correct interval timing. Considering the doses may be 3-4 weeks apart, start early,” he advised.
 

One-Time Dosing

Although the updated mRNA vaccine is currently recommended as a one-time dose, Dr. Cennimo said he can envision a scenario later in the season when a second dose is recommended for the elderly and those at high risk for severe illness. Dr. Cennimo said that he strongly agrees with the recommendations that everyone aged 6 months and older receive an updated COVID-19 vaccine. Older age remains the prime risk factor, but anyone can become infected, he said.

Predicting a prime time to get vaccinated is tricky because no one knows when the expected rise in winter cases will occur, said Dr. Cennimo.

“We know from years of flu vaccine data that some number of people who delay the vaccine will never return and will miss protection,” he said. Therefore, delaying vaccination is not recommended. Dr. Cennimo plans to follow his habit of getting vaccinated in early October. “I anticipate the maximal effectiveness of the vaccine will carry me through the winter,” he said.

Data support the safety and effectiveness for both flu and COVID vaccines if they are given together, and some research on earlier versions of COVID vaccines suggested that receiving flu and COVID vaccines together might increase the antibody response against COVID, but similar studies of the updated version have not been done, Dr. Cennimo said.

Clinicians may have to overcome the barrier of COVID fatigue to encourage vaccination, Dr. Cennimo said. Many people say they “want it to be over,” he said, but SARS-CoV-2, established as a viral respiratory infection, shows no signs of disappearing. In addition, new data continue to show higher mortality associated with COVID-19 than with influenza, he said.

“We need to explain to our patients that COVID-19 is still here and is still dangerous. The yearly influenza vaccination campaigns should have established and normalized the idea of an updated vaccine targeted for the season’s predicated strains is expected,” he emphasized. “We now have years of safety data behind these vaccines, and we need to make a strong recommendation for this protection,” he said.

COVID-19 vaccines are covered by private insurance, as well as by Medicare and Medicaid, according to the CDC. Vaccination for uninsured children is covered through the Vaccines for Children Program.

This transcript has been edited for clarity. 

New updated COVID vaccines are now available, but who can get them, who should get them, and when? Two updated mRNA COVID vaccines, one by Moderna and the other by Pfizer, have been authorized or approved by the US Food and Drug Administration (FDA) for those aged 6 months or older.

Both vaccines target Omicron’s KP.2 strain of the JN.1 lineage. An updated protein-based version by Novavax, also directed at JN.1, has been authorized, but only for those aged 12 years or older. 

The Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices recommends a dose of the 2024-2025 updated COVID vaccine for everyone aged 6 months or older. This includes people who have never been vaccinated against COVID, those who have been vaccinated, as well as people with previous COVID infection. 

The big question is when, and FDA and CDC have set some parameters. For mRNA updated vaccines, patients should wait at least 2 months after their last dose of any COVID vaccine before getting a dose of the updated vaccine.

If the patient has recently had COVID, the wait time is even longer: Patients can wait 3 months after a COVID infection to be vaccinated, but they don’t have to. FDA’s instructions for the Novavax version are not as straightforward. People can get an updated Novavax dose at least 2 months after their last mRNA COVID vaccine dose, or at least 2 months after completing a Novavax two-dose primary series. Those two Novavax doses should be given at least 3 weeks apart. 

Patients can personalize their vaccine plan. They will have the greatest protection in the first few weeks to months after a vaccine, after which antibodies tend to wane. It is a good idea to time vaccination so that protection peaks at big events like weddings and major meetings.

If patients decide to wait, they run the risk of getting a COVID infection. Also keep in mind which variants are circulating and the amount of local activity. Right now, there is a lot of COVID going around, and most of it is related to JN.1, the target of this year’s updated vaccine. If patients decide to wait, they should avoid crowded indoor settings or wear a high-quality mask for some protection. 

Here’s the bottom line: Most people (more than 95%) have some degree of COVID protection from previous infection, vaccination, or both. But if they haven’t recently had COVID infection and didn’t get a dose of last year’s vaccine, they are sitting ducks for getting sick without updated protection. The best way to stay well is to get a dose of the updated vaccine as soon as possible. This is especially true for those in high-risk groups or who are near someone who is high risk. 

Two thirds of COVID hospitalizations are in those aged 65 or older. Hospitalization rates are highest for those aged 75 or older and among infants under 6 months of age. These babies are too young to be vaccinated, but maternal vaccination during pregnancy and breastfeeding can help protect them. 

We’re still seeing racial and ethnic disparities in COVID-related hospitalizations, which are highest among American Indians, Alaska Natives, and Black populations. People with immunocompromising conditions, those with chronic medical conditions, and people living in long-term care facilities are also at greater risk. Unlike last year, additional mRNA doses are not recommended for those aged 65 or older at this time, but that could change.

Since 2020, we’ve come a long way in our fight against COVID, but the battle is still on. In 2023, nearly a million people were hospitalized from COVID. More than 75,000 died. COVID vaccines help protect us from severe disease, hospitalization, and death. 

Let’s face it — we all have booster fatigue, but COVID is now endemic. It’s here to stay, and it’s much safer to update antibody protection with vaccination than with infection. Another benefit of getting vaccinated is that it decreases the chance of getting long COVID. The uptake of last year’s COVID vaccine was abysmal; only about 23% of adults and 14% of children received it.

But this is a new year and a new vaccine. Please make sure your patients understand that the virus has changed a lot. Antibodies we built from previous infection and previous vaccination don’t work as well against these new variants. Antibody levels wane over time, so even if they missed the last few vaccine doses without getting sick, they really should consider getting a dose of this new vaccine. The 2024-2025 updated COVID vaccine is the best way to catch up, update their immunity, and keep them protected. 

Furthermore, we are now entering respiratory virus season, which means we need to think about, recommend, and administer three shots if indicated: COVID, flu, and RSV. Now is the time. Patients can get all three at the same time, in the same visit, if they choose to do so. 

Your recommendation as a physician is powerful. Adults and children who receive a healthcare provider recommendation are more likely to get vaccinated.

New updated COVID vaccines are now available, but who can get them, who should get them, and when? Two updated mRNA COVID vaccines, one by Moderna and the other by Pfizer, have been authorized or approved by the US Food and Drug Administration (FDA) for those aged 6 months or older.

Both vaccines target Omicron’s KP.2 strain of the JN.1 lineage. An updated protein-based version by Novavax, also directed at JN.1, has been authorized, but only for those aged 12 years or older. 

The Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices recommends a dose of the 2024-2025 updated COVID vaccine for everyone aged 6 months or older. This includes people who have never been vaccinated against COVID, those who have been vaccinated, as well as people with previous COVID infection. 

The big question is when, and FDA and CDC have set some parameters. For mRNA updated vaccines, patients should wait at least 2 months after their last dose of any COVID vaccine before getting a dose of the updated vaccine.

If the patient has recently had COVID, the wait time is even longer: Patients can wait 3 months after a COVID infection to be vaccinated, but they don’t have to. FDA’s instructions for the Novavax version are not as straightforward. People can get an updated Novavax dose at least 2 months after their last mRNA COVID vaccine dose, or at least 2 months after completing a Novavax two-dose primary series. Those two Novavax doses should be given at least 3 weeks apart. 

Patients can personalize their vaccine plan. They will have the greatest protection in the first few weeks to months after a vaccine, after which antibodies tend to wane. It is a good idea to time vaccination so that protection peaks at big events like weddings and major meetings.

If patients decide to wait, they run the risk of getting a COVID infection. Also keep in mind which variants are circulating and the amount of local activity. Right now, there is a lot of COVID going around, and most of it is related to JN.1, the target of this year’s updated vaccine. If patients decide to wait, they should avoid crowded indoor settings or wear a high-quality mask for some protection. 

Here’s the bottom line: Most people (more than 95%) have some degree of COVID protection from previous infection, vaccination, or both. But if they haven’t recently had COVID infection and didn’t get a dose of last year’s vaccine, they are sitting ducks for getting sick without updated protection. The best way to stay well is to get a dose of the updated vaccine as soon as possible. This is especially true for those in high-risk groups or who are near someone who is high risk. 

Two thirds of COVID hospitalizations are in those aged 65 or older. Hospitalization rates are highest for those aged 75 or older and among infants under 6 months of age. These babies are too young to be vaccinated, but maternal vaccination during pregnancy and breastfeeding can help protect them. 

We’re still seeing racial and ethnic disparities in COVID-related hospitalizations, which are highest among American Indians, Alaska Natives, and Black populations. People with immunocompromising conditions, those with chronic medical conditions, and people living in long-term care facilities are also at greater risk. Unlike last year, additional mRNA doses are not recommended for those aged 65 or older at this time, but that could change.

Since 2020, we’ve come a long way in our fight against COVID, but the battle is still on. In 2023, nearly a million people were hospitalized from COVID. More than 75,000 died. COVID vaccines help protect us from severe disease, hospitalization, and death. 

Let’s face it — we all have booster fatigue, but COVID is now endemic. It’s here to stay, and it’s much safer to update antibody protection with vaccination than with infection. Another benefit of getting vaccinated is that it decreases the chance of getting long COVID. The uptake of last year’s COVID vaccine was abysmal; only about 23% of adults and 14% of children received it.

But this is a new year and a new vaccine. Please make sure your patients understand that the virus has changed a lot. Antibodies we built from previous infection and previous vaccination don’t work as well against these new variants. Antibody levels wane over time, so even if they missed the last few vaccine doses without getting sick, they really should consider getting a dose of this new vaccine. The 2024-2025 updated COVID vaccine is the best way to catch up, update their immunity, and keep them protected. 

Furthermore, we are now entering respiratory virus season, which means we need to think about, recommend, and administer three shots if indicated: COVID, flu, and RSV. Now is the time. Patients can get all three at the same time, in the same visit, if they choose to do so.

When pediatrician Eric Ball, MD, opened a refrigerator full of childhood vaccines, all the expected shots were there — DTaP, polio, pneumococcal vaccine — except one.

“This is where we usually store our COVID vaccines, but we don’t have any right now because they all expired at the end of last year and we had to dispose of them,” said Dr. Ball, who is part of a pediatric practice in Orange County, California.

“We thought demand would be way higher than it was.”

Pediatricians across the country are preordering the updated and reformulated COVID-19 vaccine for the fall and winter respiratory virus season, but some doctors said they’re struggling to predict whether parents will be interested. Providers like Dr. Ball don’t want to waste money ordering doses that won’t be used, but they need enough on hand to vaccinate vulnerable children.

The Centers for Disease Control and Prevention recommends that anyone 6 months or older get the updated COVID vaccination, but in the 2023-24 vaccination season only about 15% of eligible children in the United States got a shot.

Dr. Ball said it was difficult to let vaccines go to waste in 2023. It was the first time the federal government was no longer picking up the tab for the shots, and providers had to pay upfront for the vaccines. Parents would often skip the COVID shot, which can have a very short shelf life, compared with other vaccines.

“Watching it sitting on our shelves expiring every 30 days, that’s like throwing away $150 repeatedly every day, multiple times a month,” Dr. Ball said.

in 2024, Dr. Ball slashed his fall vaccine order to the bare minimum to avoid another costly mistake.

“We took the number of flu vaccines that we order, and then we ordered 5% of that in COVID vaccines,” Dr. Ball said. “It’s a guess.”

That small vaccine order cost more than $63,000, he said.

Pharmacists, pharmacy interns, and techs are allowed to give COVID vaccines only to children age 3 and up, meaning babies and toddlers would need to visit a doctor’s office for inoculation.

It’s difficult to predict how parents will feel about the shots this fall, said Chicago pediatrician Scott Goldstein, MD. Unlike other vaccinations, COVID shots aren’t required for kids to attend school, and parental interest seems to wane with each new formulation. For a physician-owned practice such as Dr. Goldstein’s, the upfront cost of the vaccine can be a gamble.

“The cost of vaccines, that’s far and away our biggest expense. But it’s also the most important thing we do, you could argue, is vaccinating kids,” Dr. Goldstein said.

Insurance doesn’t necessarily cover vaccine storage accidents, which can put the practice at risk of financial ruin.

“We’ve had things happen like a refrigerator gets unplugged. And then we’re all of a sudden out $80,000 overnight,” Dr. Goldstein said.

South Carolina pediatrician Deborah Greenhouse, MD, said she would order more COVID vaccines for older children if the pharmaceutical companies that she buys from had a more forgiving return policy.

“Pfizer is creating that situation. If you’re only going to let us return 30%, we’re not going to buy much,” she said. “We can’t.”

Greenhouse owns her practice, so the remaining 70% of leftover shots would come out of her pocket.

Vaccine maker Pfizer will take back all unused COVID shots for young children, but only 30% of doses for people 12 and older.

Pfizer said in an Aug. 20 emailed statement, “The return policy was instituted as we recognize both the importance and the complexity of pediatric vaccination and wanted to ensure that pediatric offices did not have hurdles to providing vaccine to their young patients.”

Pfizer’s return policy is similar to policies from other drugmakers for pediatric flu vaccines, also recommended during the fall season. Physicians who are worried about unwanted COVID vaccines expiring on the shelves said flu shots cost them about $20 per dose, while COVID shots cost around $150 per dose.

“We run on a very thin margin. If we get stuck holding a ton of vaccine that we cannot return, we can’t absorb that kind of cost,” Dr. Greenhouse said.

Vaccine maker Moderna will accept COVID vaccine returns, but the amount depends on the individual contract with a provider. Novavax will accept the return of only unopened vaccines and doesn’t specify the amount they’ll accept.

Dr. Greenhouse wants to vaccinate as many children as possible but said she can’t afford to stock shots with a short shelf life. Once she runs out of the doses she’s ordered, Dr. Greenhouse plans to tell families to go to a pharmacy to get older children vaccinated. If pediatricians around the country are making the same calculations, doses for very small children could be harder to find at doctors’ offices.

“Frankly, it’s not an ideal situation, but it’s what we have to do to stay in business,” she said.

Dr. Ball worries that parents’ limited interest has caused pediatricians to minimize their vaccine orders, in turn making the newest COVID shots difficult to find once they become available.

“I think there’s just a misperception that it’s less of a big deal to get COVID, but I’m still sending babies to the hospital with COVID,” Dr. Ball said. “We’re still seeing kids with long COVID. This is with us forever.”
