TOPLINE:
A new study shows young children with October birthdays may have better protection against flu.
METHODOLOGY:
- Researchers analyzed data from the MarketScan Research Database between 2011 and 2018.
- They focused on 819,223 children aged 2-5 years who were vaccinated against influenza between August 1 and January 31 and whose birthdays fell during that window.
TAKEAWAY:
- Children born in October had the lowest rate of influenza diagnosis, with an average diagnosis rate of 2.7%, whereas those born in August had a diagnosis rate of 3%.
- Compared with children born in August, the adjusted odds ratio for influenza diagnosis in children born in October was 0.88 (95% CI, 0.85-0.92).
IN PRACTICE:
“The findings support current recommendations that children be vaccinated in October preceding a typical influenza season,” the authors of the study wrote.
SOURCE:
Anupam B. Jena, MD, PhD, with Harvard Medical School and Massachusetts General Hospital in Boston, Massachusetts, was the corresponding author on the study. The research was published online in BMJ .
LIMITATIONS:
The availability of the influenza vaccine and the peak of seasonal flu infections vary by year and region.
DISCLOSURES:
Researchers disclosed consulting fees from pharmaceutical and healthcare companies unrelated to the study.
