Childhood immunizations (shots), help keep your baby or child from getting sick. Most vaccines are given as shots, but some are given by mouth. They work by helping the body fight illness. In most cases, the shots will prevent your baby from getting serious diseases.
Your baby will need shots at different times. If your baby does get sick, it will most likely be a much milder case. Protect your child from getting sick by using the immunization schedule set up by your doctor. An immunization schedule tells you which shots your child should get and when they should get them. The immunization schedule helps your baby stay on track with his or her shots.
