What Do Vaccines Do?

Vaccines work by preparing the body to fight illness. Each contains either a dead or a weakened germ (or parts of it) that causes a particular disease.

The body practices fighting the disease by making antibodies that recognize specific parts of that germ. This permanent or longstanding response means that if someone is ever exposed to the actual disease, the antibodies are already in place and the body knows how to combat it and the person doesn’t get sick. This is called immunity.

Freequently asked questions

No, the immune system makes antibodies against a germ, like the chickenpox virus, whether it encounters it naturally or is exposed to it through a vaccine. Being vaccinated against one disease does not weaken the immune response to another disease.

The most common reactions to vaccines are minor and include:

  • redness and swelling where the shot was given
  • fever
  • soreness at the site where the shot was given

Read Your Child’s Immunizations for details about each recommended immunization. You also can visit the CDC’s National Immunization Program website for more information about vaccinations.

And talk with your doctor about which immunizations your kids need. Working together, you can help keep your family healthy.
