when should you get your flu shot

The best time to get your flu shot is generally in September or October. This timing is recommended because it allows your body about two weeks to build immunity before the flu season starts ramping up in October and peaks between December and February. Getting the vaccine too early may reduce its effectiveness later in the season due to waning immunity. However, it is still beneficial to get vaccinated later in the season, even into November or early winter, as flu activity can continue as late as May. Special cases include young children who may need two doses spaced apart and pregnant women who might get vaccinated earlier in the season to protect both themselves and their infants. For most adults, flu vaccines are available starting in October. Overall, the goal is to get vaccinated before flu viruses circulate widely.
