Immunizations help keep you and your child from getting a disease. They contain medicine that causes the body to make antibodies. These antibodies can then recognize and fight the disease if you or your child is later exposed to it.
The American Academy of Pediatrics recommends that children be immunized with the varicella zoster vaccine to prevent chicken pox usually after the age of 1. A second dose, typically given at about age 4 or 5, is needed for complete protection.
The vaccine is also a protection to vulnerable people, such as non-immune women who plan to become pregnant. Some, such as those who are already pregnant, are not eligible to receive the chickenpox vaccine. Consult your doctor for advice.

Vaccines are the best way we have to prevent infectious diseases. A successful vaccine program depends on everyone getting vaccinated.
When should my child be immunized?
Ask your doctor what shots your child should get. The U.S. Centers for Disease Control and Prevention (CDC) keeps a list of shots needed for each age group.
Why do I have to use the government schedule? Can't I use my own schedule?
The schedule recommended by experts is designed to work best with a child's immune system at certain ages and at certain times. The schedule is set up so that your child gets the best protection possible at the earliest age possible from the fewest shots possible.
Experts review the schedules every year based on the best research available and change the schedules as needed.
A different schedule may not provide protection for your child. If shots are spread out or skipped, a child may get the disease during the delay.
Why does my child need so many doses to protect against one disease?
Your child gets as many shots as needed to give him or her full protection from a disease. This may be one shot only, or it may be several doses.
More than one dose may be needed because immunity may have to build up over time. You want the best combination of immediate and future protection for your child. This means that your child needs a certain amount of vaccine spaced apart at different ages. This builds the best protection.
