Why childhood vaccines matter

Vaccines have been used for decades to help teach the body how to fight off dangerous diseases. Extensive research and testing go into every vaccine, making them a safe and highly effective way to protect your family’s health now and into the future. 

The use of vaccines over the years has saved millions of lives. Widespread vaccination also helps prevent the spread of disease and protects those who can’t be vaccinated.*

Vaccinations for young children are especially important. Since their immune systems aren’t fully developed, they have a higher risk of serious illness if infected. Vaccines are one of the most powerful tools available to help keep them safe.

Vaccines help protect them when we can’t. Visit our dedicated childhood vaccine page to learn more about:
