âAny time you get a flu shot is better than not getting a flu shot, but my best guess is that getting your flu shot in mid-October will give you the best chance of avoiding the flu this year,â says Jorge P. Parada, MD, a professor of medicine and director of the infection control program at Loyola University in Chicago.
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.
