Can the Shot Give Me the Flu?
One common question people often ask about flu vaccines is, “Can a flu shot give me the flu?”
The answer is no. The viruses contained in flu shots are inactivated (killed), so they cannot cause infection.
It is still possible, however, to get the flu after getting a flu shot. The flu vaccine is not 100% effective and does not take effect until one or two weeks after it is received. During this time, you will be just as susceptible to getting the flu as individuals who have not received the vaccination. However, the vaccination can also make your symptoms milder in the event you do get the flu.
