Influenza virus vaccine is used to prevent infection by the influenza viruses. The vaccine works by causing your body to produce its own protection (antibodies) against the disease.
There are many kinds of influenza viruses, but not all will cause problems in any given year. Therefore, before the influenza vaccine is produced each year, the World Health Organization (WHO) and the U.S. and Canadian Public Health Services decide which viruses will most likely cause influenza infections for that year. The antigens, which are substances that cause protective antibodies to be formed, for these viruses are included in the influenza vaccine. Usually, the U.S. and Canada use the same influenza vaccine; however, they are not required to do so.
It is necessary to receive an influenza vaccine each year, since influenza infections are usually caused by different kinds of viruses and the protection gained by the vaccine lasts less than a year.
Influenza is a virus infection of the throat, bronchial tubes, and lungs. Influenza infection causes fever, chills, cough, headache, muscle aches, and pains in your back, arms, and legs. In addition, adults and children weakened by other diseases or medical conditions, and persons 50 years of age and over, even if they are healthy, may get a much more serious illness that may have to be treated in a hospital. Each year thousands of people die as a result of an influenza infection.
The best way to help prevent influenza infections is to get an influenza vaccination each year, usually in early November. Immunization (getting a vaccine) against influenza is approved for infants 6 months of age and over, all children, and all adults.
This vaccine is to be administered only by or under the supervision of your doctor or other health care professional.
