/Can vaccines overload my baby’s immune system?

Vaccines do not overload the immune system. Every day, a healthy baby’s immune system successfully fights off millions of germs. Antigens are parts of germs that cause the body’s immune system to go to work.

The antigens in vaccines come from the germs themselves, but the germs are weakened or killed so they cannot cause serious illness. Even if they receive several vaccinations in one day, vaccines contain only a tiny fraction of the antigens that babies encounter every day in their environment.

Vaccines provide your child with the antibodies they need to fight off the serious illnesses for which they have been vaccinated.
