Vaccine Side Effects (What to Expect)
Different side effects can be associated with the flu shot and LAIV.
The flu shot: The viruses in the flu shot are killed (inactivated), so you cannot get the flu from a flu shot. Some minor side effects that could occur are:
- Soreness, redness, or swelling where the shot was given
- Fever (low grade)
- Aches
If these problems occur, they begin soon after the shot and usually last 1 to 2 days. Almost all people who receive influenza vaccine have no serious problems from it. However, on rare occasions, flu vaccination can cause serious problems, such as severe allergic reactions. As of July 1, 2005, people who think that they have been injured by the flu shot can file a claim for compensation from the National Vaccine Injury Compensation Program (VICP)
.
The nasal spray (also called LAIV or FluMist®): The viruses in the nasal-spray vaccine are weakened and do not cause severe symptoms often associated with influenza illness. (In clinical studies, transmission of vaccine viruses to close contacts has occurred only rarely.)
In children, side effects from LAIV (FluMist®) can include:
- runny nose
- wheezing
- headache
- vomiting
- muscle aches
- fever
In adults, side effects from LAIV (FluMist®) can include
- runny nose
- headache
- sore throat
- cough
