Chickenpox Vaccine for Children


What is the chickenpox vaccine?

The chickenpox vaccine is an injection given to your child to protect him or her from chickenpox. Chickenpox is a common childhood infection caused by the varicella-zoster virus. The virus causes fever and an itchy rash that spreads over the entire body. The rashes turn into small blisters that dry up to form scabs. The infection may spread and damage your child's skin, lungs, and brain. The chickenpox vaccine may be given by itself or combined with other vaccines.

Who should get the chickenpox vaccine?

Your child should receive 2 chickenpox vaccines. The first dose is given at 12 to 15 months. The second dose is given at 4 to 6 years. The second dose may be given before a child is 4 years old if at least 3 months have passed since the first dose. There must be at least 3 months between doses for children younger than 13 years old. There must be at least 4 weeks between doses for children 13 years or older.
