and testing

Vaccines prevent up to 3 million deaths worldwide every year.

In the UK vaccines have eradicated smallpox, polio, and tetanus. Vaccines have also helped reduce the number of people suffering from measles and diphtheria.

Sadly, some diseases that had disappeared are on the rise again in the UK, like measles. This is because of vaccine hesitancy.


Vaccines are still the safest and most effective way to prevent you and your family from becoming seriously ill.

Vaccines contain weakened or inactive parts of a disease. This weakened version does not cause the disease. It triggers an immune response in the body. This allows our body to learn how to defeat the disease, before encountering it.
