There are very few people who cannot have a flu vaccine.
People who have previously had a serious allergic reaction to a flu vaccine or a serious allergic reaction to any of the ingredients of the vaccine should not have that vaccine again.
Tell the nurse or doctor if you have a serious egg allergy. You can still have a flu vaccine, but special arrangements might be needed.
A cold or other minor illness is not a reason to delay a flu vaccination.
If you are unwell with a high temperature, delay the vaccination until you feel better.
