What is the Flu Vaccine?

The flu vaccine, also known as the flu jab, is a vaccine that is available every year to protect adults, the elderly and other vulnerable people from the flu virus. The flu vaccine is available to everyone, but certain groups are strongly encouraged to get the vaccine as they are at an increased risk of severe complications from having the flu vaccine, this includes people over the age of 65, pregnant women, people with a compromised immune system and those with long term heart of lung conditions.

How is the Flu Vaccine performed?

The vaccine is given to children as a nasal spray and to adults as an injection. A vaccine is a dead or modified version of the virus, which the body is able to create antibodies to. Once an antibody is created, the body stores it in its immune memory, so that if the real virus enters the body, the antibody is already created and can destroy the flu virus.

How to prepare for the Flu Vaccine?

Before any vaccination you will have to fill out a form letting the person know who is giving you the vaccine if you suffer from any long term health conditions in case they interfere with the flu vaccine or if you have any allergies.

What happens after a Flu Vaccine?

After the vaccine you may experience a dull ache in your arm where the needle went in and you may feel a bit feverish for a day or so. This should ease in a few days and you can take paracetamol to help relieve these symptoms. Serious side effects of the flu vaccine are very rare. The vaccine does not fully protect you against the flu virus, so you may still contract the flu. If you have any further questions on the flu vaccine you GP will be able to give you more information on the procedure.
