Vaccines help protect infants, children, and teens from serious diseases. Getting childhood vaccines means your child can develop immunity (protection) against diseases before they come into contact with them. And did you know that getting your child vaccinated also protects others? Because of community immunity, vaccines help keep your child’s younger siblings, older family members, and friends from getting sick, too.
Why do vaccinations start so early?
Young children are at increased risk for infectious diseases because their immune systems have not yet built up the necessary defenses to fight serious infections and diseases. As a result, diseases like whooping cough or pneumococcal disease can be very serious — and even deadly — for infants and young children. Vaccinations start early in life to protect children before they are exposed to these diseases.
