Impact of 2-dose vaccination on varicella epidemiology: Connecticut--2005-2008.

In 2006, the Advisory Committee on Immunization Practices recommended that children routinely receive 2 varicella vaccine doses in place of the 1 dose previously recommended. This recommendation's initial impact on varicella epidemiology in Connecticut was assessed. Reported incidence and case-specific data were compared for 2005 and 2008.
