For the Consumer

Applies to influenza virus vaccine, inactivated: solution, suspension

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, studies have shown that the risk of acquiring GBS from an influenza vaccine is very low (one out of every million people).

In addition to its needed effects, some unwanted effects may be caused by influenza virus vaccine, inactivated (the active ingredient contained in Afluria). In the event that any of these side effects do occur, they may require medical attention.
