Abstract
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. Varicella incidence decreased from 48.7 cases/100,000 persons in 2005 to 24.5 in 2008. Age-specific incidence decreased significantly (P < .05) among children aged 1-14 years. Reported varicella incidence has declined in Connecticut after implementation of routine 2-dose varicella vaccination for children. Continued surveillance is needed to determine the recommendation's full impact.
