Vaccines are usually given in childhood days to protect against serious, often life threatening diseases. Vaccines help your immune system fight infections more efficiently by sparking your immune response to specific diseases.

If the virus or bacteria ever invades your body in the future, your immune system will already know how to fight it.

Vaccines are safe. Measles vaccines alone are estimated to have prevented over 21 million deaths between 2000 and 2017.

Vaccines will help protect your child against diseases that can cause serious harm or death, especially in people with developing immune systems like infants.
