Literature review on one-dose and two-dose varicella vaccination

In 2006, the Advisory Committee on Immunization Practices (ACIP) approved a routine 2-dose varicella vaccination schedule for children. The purpose of this document is to review information on the epidemiology of varicella, compare the effectiveness of one dose of varicella vaccine with two doses, and to consider a potential change to the current National Advisory Committee on Immunization (NACI) recommendation for a one-dose childhood varicella vaccination program.
