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.
