Facts about vaccines & immunization

How does a vaccine work?

  • A vaccine helps your body fight off disease by kick-starting your body’s natural protective mechanisms.

  • The vaccine introduces a small amount of an agent that resembles a disease, into your body in a weakened or dead form.

  • Your body mounts a defense against this intruder, forming antibodies against the real disease.

  • If you encounter the disease in the wild, your body is already equipped to fight it off.

  • Some antibodies stay with you for a lifetime; others fade with time.

  • A simple blood test can indicate whether or not you need a booster for one of your vaccines or immunizations.
