Baby and childhood immunisation pages on the NHS website

Vaccines are the most effective way to prevent infectious diseases. Since vaccines were introduced in the UK, diseases like smallpox and tetanus that used to kill or disable millions of people are either gone or seen very rarely.

Other diseases like measles and diptheria have been reduced by up to 99.9% since their vaccines were introduced.
