• The varicella vaccine helps protect against chickenpox (varicella), a very contagious infection caused by the varicella-zoster virus. It causes an itchy rash that looks like small blisters with a red base. In some people, the brain, lungs, and heart can become infected, resulting in serious illness or death. The virus remains in the body after the illness has resolved. If it is reactivated, it can cause shingles years later.
