INFLUENZA VIRUS VACCINE helps to reduce the risk of getting influenza also known as the flu. The vaccine only helps protect you against some strains of the flu. Compare vaccinations.

Fluarix Quadrivalent Side Effects

What should I watch for?

Report any side effects that do not go away within 3 days to your doctor or health care professional. Call your health care provider if any unusual symptoms occur within 6 weeks of receiving this vaccine.

You may still catch the flu, but the illness is not usually as bad. You cannot get the flu from the vaccine. The vaccine will not protect against colds or other illnesses that may cause fever. The vaccine is needed every year.


Interactions with Medications

In 1976, a number of people who received the “swine fluinfluenza 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, 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.
