How do vaccines work?

Vaccines trigger your own immune system to fight off and prevent certain kinds of disease in the future. A vaccine uses a tiny amount of substance that lets your body build up antibodies and other defenses to a virus or bacteria. This helps to prevent or lessen the severity of many types of diseases caused by infection.

A vaccine is most often done with an injection by a small needle into your arm. Some vaccines work in 1 shot. Others need to be done in 2 or more shots over a period of time. This lets your immune system build up the right amount of defenses.

Combination vaccines can help prevent more diseases with fewer shots. These vaccines have more than 1 type of prevention in a single dose.
