Vaccination: A Vital Tool for Public Health

Vaccines are one of the most effective tools in public health. They have saved millions of lives and are essential for protecting people from infectious diseases. The World Health Organization (WHO) is working to increase vaccination rates worldwide.

Vaccines work by exposing the body to a weakened or inactive form of a virus or bacteria. This helps the body develop immunity to the disease, so that if the person is exposed to the real virus or bacteria, they will not get sick.

Vaccines are safe and effective. There are many different types of vaccines available, and they are all rigorously tested before they are approved for use. Vaccines have been shown to be very effective at preventing a wide range of diseases, including measles, mumps, rubella, polio, and diphtheria.

The WHO is committed to ensuring that everyone has access to safe and effective vaccines. The organization works with governments, health care providers, and other partners to increase vaccination rates around the world.
