- The newborn and infant vaccine schedule protects against several serious diseases that can be especially dangerous early in life.
- Recommended early vaccines include protection against whooping cough, tetanus, diphtheria, Hib, polio, RSV, rotavirus, pneumococcal disease, and hepatitis B.
- Once infants reach six months, flu and COVID vaccines are added, followed by measles, mumps, rubella, chickenpox, and hepatitis A.
- The timing and combinations of these vaccines are extensively tested for safety and effectiveness.
- Vaccinating infants strengthens their immune defenses quickly and safely without overwhelming the immune system.
- Everyday exposures, such as crawling on floors or interacting with pets, naturally challenge and build a baby’s immune system even further.
What is the Vaccine Schedule for Newborns and Infants
The infant vaccine schedule is designed to build strong, safe immunity when babies need it most—without overwhelming their tiny immune systems.
