- Vaccines act as practice for the immune system, helping it learn how to fight serious diseases safely.
- Just like skill-building in other areas, early exposure through vaccines prepares the body for real-world infections.
- Babies are naturally exposed to thousands of germs daily, so their immune systems are built to handle multiple challenges.
- The number of vaccines given does not overwhelm the immune system, as it can easily manage additional exposures.
- Providing vaccines on schedule ensures infants are protected early against potentially dangerous diseases.
Vaccines Are Practice
Vaccines safely train a baby’s immune system to recognize and fight serious diseases without overwhelming it.
