A vaccine, like any medicine, could possibly cause serious problems, such as severe allergic reactions. The risk of a vaccine causing serious harm, or death, is extremely small. Serious problems from Flu vaccine are very rare. The viruses in inactivated Flu vaccine have been killed, so you cannot get Flu from the vaccine.

If these problems occur, they usually begin soon after the shot and last 1-2 days.
