What should I watch for?
Report any side effects to your doctor right away.
After receiving this vaccine, stay away from people who have severe immune system problems for 7 days. You may give them the flu.
Remember that this vaccine lowers your risk of getting the flu. You can get a milder flu infection if you are around others with the flu. The flu vaccine will not protect against colds or other illnesses. A yearly vaccination is recommended. Ask your health care professional about immunization for other family members.
Common and Rare 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.
