Getting the flu shot any time throughout respiratory virus season is healthier than not getting it in any respect. However vaccine safety wanes, so timing the shot correctly may help antibodies peak when instances are highest.
Researchers needed to determine the optimum time for getting a flu shot, and took benefit of the truth that youngsters are inclined to get vaccinated within the month they had been born. In a study published in BMJ, they analyzed medical health insurance information from greater than 800,000 youngsters, ages 2-5, who bought a flu shot from 2011 to 2018. The info confirmed that youngsters vaccinated in October had the strongest safety—they had been about 12% much less prone to get the flu in comparison with youngsters vaccinated in August.
“It is sensible that October is the best time to get vaccinated,” says the research’s senior creator Dr. Anupam Jena, professor of well being care coverage at Harvard Medical College and professor of medication at Massachusetts Basic Hospital. Get vaccinated in August or September, and immunity may wane too quickly; get the shot in December or January, and immunity won’t have time to construct up earlier than the December or January peak, he says. October appears to be the candy spot. “These findings present a data-driven option to present that’s true.”

Pediatricians may put this discovering into apply by discussing optimum timing of the shot and “doubling down on October appointments,” says Jena. “To the extent that they’ll extra forcibly advocate that October is the optimum time for teenagers to get vaccinated, we’d see dad and mom transferring to get photographs in that month.”
Different methods could embrace specializing in school-based vaccination applications. “For issues like flu vaccines, comfort is a very massive deal, and making them extra accessible at school would resolve the issue of many youngsters not getting vaccinated within the first place, in addition to facilitating optimum timing,” says Jena.
Getting the flu shot in October may be essential in serving to youngsters with weakened immune methods get the very best safety potential towards extreme sickness and hospitalization. “In case you are prone to having flu-related problems, optimum timing of the shot could matter much more,” says Jena. “For these youngsters, they get a bigger bang for his or her buck if they’re vaccinated in October.”
For the reason that research solely concerned youngsters, it’s not clear if the identical impact will maintain for adults. However since youngsters are among the many most effective spreaders of the flu, ensuring youngsters are protected may additionally result in fewer instances amongst adults, Jena says. “If youngsters are going to get vaccinated, you may as effectively optimize the time at which they get the shot.”
