In the meantime, the person is susceptible to becoming ill.

Vaccination is the most important thing we can do to protect ourselves and our children against ill health. They prevent up to 3 million deaths worldwide every year.

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

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

However, if people stop having vaccines, it's possible for infectious diseases to quickly spread again.

Information:

The World Health Organization (WHO) has listed vaccine hesitancy as one of the biggest threats to global health.

Vaccine hesitancy is where people with access to vaccines delay or refuse vaccination.

Some parents had concerns about the effectiveness of vaccines. They said that the need for vaccine boosters raises doubts about long-term effectiveness and that they knew of children who were vaccinated against a disease and yet later caught it. Some also believed that new disease strains could appear and then the vaccine would be ineffective
