Vaccines in the Western Pacific

Immunization is the process whereby a person is made resistant to an infectious disease, typically usually by the administration of a vaccine. The agent in a vaccine stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it. In this way, the immune system can more easily recognize and destroy any of these microorganisms in future encounters.

There are available vaccines against 23 diseases (or pathogens that cause them). Combined vaccines protect against multiple diseases by using a single product. A number of new vaccines are in the pipeline, at different stages of development.
