Will the flu vaccine give me or my child the flu?

A flu shot cannot cause flu illness. The flu vaccine does not have a live virus in it, so it is impossible to get the flu from the vaccine.

The most common side effects from the flu shot are soreness, redness, tenderness or swelling where the shot was given. Low-grade fever, headache and muscle aches also may occur. These are expected side effects from the vaccine and generally do not last long. These reactions should not be misinterpreted as getting sick with flu from the vaccine. The most common reactions people have to the flu vaccine are considerably less severe than the symptoms caused by actual flu illness.

Serious allergic reactions to flu vaccines are very rare. If they do occur, it is usually within a few minutes to a few hours after the vaccination. If you have questions or concerns about the flu vaccine, be sure to talk to your child’s doctor.
