By the use of attenuated varicella vaccine, which disease can be prevented?

The varicella vaccine is a live (attenuated) virus that protects against the viral disease commonly known as chickenpox caused by the varicella zoster virus (VZV). The varicella vaccine is marketed as varivax in the U.S and globally as varilrix by glaxosmithkline. Another vaccine that is known as Zostavax is simply a larger than normal dose of varivax, and is used to reduce the risk of shingles also called herpes zoster and postherpetic neuralgia that are caused by the same virus.
