Uses For Fluzone

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. It is also known as a “flu shot” .

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 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 .

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 .

Influenza virus vaccine may not protect all persons given the vaccine .

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

Fluzone Side Effects

In 1976, a number of people who received the “swine flu” influenza vaccine developed Guillain-Barré syndrome (GBS), which is a disease that may cause paralysis. Most of these people were over 25 years of age. Although only 10 out of every one million people who received the vaccine actually developed GBS, this number was 6 times higher than would normally have been expected. Most of the people who got GBS recovered completely.

It is assumed that the “swine flu” virus included in the 1976 vaccine caused the problem, but this has not been proven. Since that time, the “swine flu” virus has not been used in influenza vaccines, and there has been no recurrence of GBS that was associated with influenza vaccinations.

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
