NHS Choices provide lots of information about vaccinations including Flu. Click here
for a checklist of the vaccines that are routinely offered to everyone in the UK for free on the NHS, and the ages at which they should ideally be given.
If you're not sure whether you or your child have had all your routine vaccinations, ask your GP or practice nurse to find out for you. It may be possible to catch up later in life.
Try to have your vaccinations delivered on time to ensure protection. If you're going to be away from the GP surgery when a vaccination is due, talk to your doctor. It may be possible to arrange to have the vaccination at a different location.
