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).
Along with its needed effects, influenza virus vaccine, inactivated (the active ingredient contained in Flucelvax) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
