Very few people are unable to have the flu jab, but you should avoid it if you have had a serious allergic reaction to the flu jab in the past.
Egg allergy
People who have egg allergy may be at increased risk of reaction to the flu vaccine 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 isn't available, your GP may be able to find a suitable flu vaccine with a low egg content.
Read more about low-egg and egg-free flu vaccines in the Department of Health's Green Book (PDF, 666Kb).
Depending on the severity of your egg allergy, your GP may decide to refer you to a specialist to have the vaccination in hospital.
Fever
If you are ill with a fever, it's best to delay your flu vaccination until you have recovered. There is no need to delay your flu jab if you have a minor illness with no fever such as a cold.
