A new study in the journal Pediatrics finds that use of the varicella (chickenpox) vaccine in the U.S., first introduced in 1995, has reduced the death rate from the disease by 97 percent among children and adolescents.

The authors note that the previous one dose recommendation was changed to two doses as of 2006, which may reduce the death rate from chicken pox even further.
