Who should not have the flu vaccine?

Very few people are unable to have the flu vaccine, but you should avoid it if you have had a serious allergic reaction to the flu vaccine in the past.

Egg allergy and the flu vaccine

People who have an egg allergy may be at increased risk of having a reaction to the injectable flu vaccine.

This is because some flu vaccines are made using eggs.

In recent years, flu vaccines that are egg-free have become available.

If an egg-free flu vaccine is not available, a GP may be able to find a suitable flu vaccine with a low egg content.

Depending on the severity of your egg allergy, the GP may decide to refer you to a specialist to have the vaccination in hospital.

If your child has needed intensive care because of an allergic reaction to egg, you should seek the advice of their specialist.

Your child may need to have the nasal spray vaccine in hospital.

Fever and the flu vaccine

If you're ill with a fever, it's best to delay your flu vaccination until you have recovered.

There's no need to delay your flu vaccine if you have a minor illness with no fever, such as a cold.
