This vaccine is used to prevent infection by the influenza (flu) virus. It is also called the seasonal flu shot. Influenza can cause serious illness (rarely death), especially in young children, older adults, and people with chronic health problems. Vaccines work by helping the body produce its own protection (antibodies) against the virus.
Vaccination is the best way to prevent infection and decrease the seriousness of illness if you become infected. The brand and dose of vaccine you receive depends on your age.
As with any vaccine, it may not fully protect everyone who receives it. Since different types of flu viruses cause infection every flu season, usually a new vaccine is produced and given for each flu season.
Redness, soreness, swelling, or itching at the injection site may occur. Headache, muscle aches, or tiredness may also occur. Usually, side effects are mild and last one to three days. If any of these effects persist or worsen, tell your health care professional promptly.
Remember that your health care professional has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
