According to the Centers for Disease Control (CDC), you should allow two weeks after getting a flu shot to develop protection against the flu. That's because after vaccination, the body has to work for a while to create the protective antibodies to the flu virus. Bear in mind, though, that there's a lot of variation in how fast different people's immune systems work.
Is it possible to get the flu from the vaccine itself? No, a flu vaccine cannot cause flu illness. Flu vaccines are made with 'inactivated' virus and therefore are not infectious. Is it too early in the season to get my flu shot? It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against influenza virus infection. That's why it's better to get vaccinated early in the fall, before the flu season really gets under way and it will last throughout the whole influenza season.
