USES: This medication 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 people at high risk from the infection (such as young children, the elderly, and people with chronic health problems). Vaccines work by causing the body to produce its own protection (antibodies) against the virus.Vaccination is the best method for preventing infection and decreasing the seriousness of illness if you become infected. The brand and dose of vaccine you receive depends on your age. Influenza vaccination is not recommended in infants less than 6 months old.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.
HOW TO USE: Read the Vaccine Information Statement available from your health care provider before receiving the vaccine. If you have any questions, consult your health care provider.The medication is usually given by injection into a muscle by a health care professional. Adults and children usually receive the injection in the upper arm, and infants receive it in the upper thigh. In Canada, certain brands can also be given by injection under the skin.The vaccination is usually given in the time from September to November when the number of cases of influenza virus begins to increase (the start of "flu season"). Only one dose is required for people aged 9 years and older. Children under 9 years of age may receive a second dose depending on when the first dose was given. Discuss the dose schedule with your doctor.

Anyone who wishes to reduce their risk of getting the flu can be vaccinated, however the U.S. Centers for Disease Control and Prevention recommends that people who are at risk for serious complications from the flu be vaccinated each year.
