how often to get flu shot

Adults and children over 6 months of age should get a flu shot every year to maintain optimal protection, as immunity from the vaccine wanes over time and flu strains change annually. The CDC recommends annual vaccination for everyone in this age group, regardless of whether it's exactly 12 months since the last dose—getting it each flu season, typically starting in September or October, ensures coverage when cases peak. Children 6 months through 8 years receiving the flu vaccine for the first time or with unknown history may need two doses, spaced at least 4 weeks apart.

Official Guidelines

Health authorities like the CDC emphasize yearly shots because the vaccine targets circulating strains that evolve each season. For older adults or high- risk groups, early vaccination in mid-September to October builds immunity before winter peaks, taking about two weeks to fully activate. Canadian guidelines align closely, advising one annual dose for those 9 and older, with two initial doses for younger kids new to vaccination.

Exceptions and Timing

No harm comes from shots spaced less than 12 months apart; the priority is aligning with flu season rather than strict yearly intervals. Flu activity often runs October through May in North America, peaking December to February, so vaccinate before exposure risks rise. Even if you've had the flu recently, annual shots remain crucial due to multiple strains.

Forum Perspectives

Online discussions, like Reddit threads, show mixed views—some skip shots yearly citing rare illness, while others prioritize them amid flu-COVID overlaps. Trending contexts highlight combined flu-COVID vaccines for efficiency, urging double protection. Key takeaway: Personal anecdotes vary, but expert consensus favors annual vaccination.

TL;DR: Get a flu shot every year , ideally September-October, for all ages 6 months+—it's safe, effective, and adapts to new strains.
