When is it too late to get a flu shot?

According to GoodRx, it is almost never too late to receive a flu shot. The vaccine continues to provide essential protection even if the flu season has already started, with its effectiveness lasting until May. This ensures that individuals can still benefit from immunization throughout the peak period. Additionally, drugstores in New York, USA, are actively advertising the availability of these flu vaccines to the public to encourage timely vaccination across the region.
