Influenza virus vaccine, recombinant is used to prevent infection caused by the influenza viruses in adults 18 years of age and older. The vaccine works by causing your body to produce its own protection (antibodies) against the disease. It is also known as a “flu shot”.

It is necessary to receive an influenza vaccine injection 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. The best way to help prevent influenza infections is to get an influenza vaccination each year, usually in early November.

This vaccine is to be given only by or under the supervision of your doctor or other health care professional.
