Most parents choose to vaccinate their children according to the recommended schedule. But some parents may still have questions about vaccines, and getting answers they can trust may be hard.

Vaccines can prevent infectious diseases that once killed or harmed many infants, children, and adults. Without vaccines, your child is at risk for getting seriously ill and suffering pain, disability, and even death from diseases like measles and whooping cough.1

Strengthening your baby’s immune system

Immunity is the body’s way of preventing disease. When your baby is born, their immune system is not fully developed, which can put them at greater risk for infections. Vaccines reduce your child’s risk of infection by working with their body’s natural defenses to help safely develop immunity to disease.2

New Parent/Grandparent Vaccines

Newborn babies do not have fully developed immune systems, making them particularly vulnerable to infections. When a baby’s family members and caregivers get vaccinated, they help form a “cocoon” of disease protection around the baby. Anyone who is around babies should be up-to-date on all routine vaccines, including the whooping cough vaccine. During flu season, everyone should get a flu vaccine in order to surround the baby with protection. Parents, brothers and sisters, grandparents, babysitters, and other caregivers can all help prevent the spread of disease by getting vaccinated.2
