In 1996, the Advisory Committee for Immunization Practices recommended 1 dose of vaccine for children, and in 2006 it recommended 2 doses; Connecticut required 1 dose for school entry in 2000 and 2 doses for school entry starting in 2011. Connecticut varicella incidence overall and among persons aged 1\u201314 years declined during 2005\u20132008. We analyzed varicella surveillance data for 2009\u20132014 to characterize overall and age group-specific trends in the setting of the 2-dose requirement.<\/jats:p>\n               <jats:p>Methods. \u2003Passive surveillance was used to collect data and identify incidence trends and changes in proportions, and these were assessed by \u03c72 tests for trend and proportion, respectively.<\/jats:p>\n               <jats:p>Results. \u2003Varicella incidence decreased from 13.8 cases\/100 000 persons during 2009 to 5.1 cases\/100 000 persons during 2014 (P &amp;lt; .001); significant declines in incidence occurred among children aged 1\u20134, 5\u20139, and 10\u201314 years (P &amp;lt; .01 for each age group). Cases classified as preventable decreased from 44% during 2009 to 25% during 2014 (P &amp;lt; .01); significant declines in percentages of preventable cases occurred only among those aged 5\u20139 years (P &amp;lt; .05) and 10\u201314 (P &amp;lt; .01) years.<\/jats:p>\n               <jats:p>Conclusions. \u2003Varicella incidence continued to decline in Connecticut in the setting of the 2-dose school-entry program. Continued surveillance is needed to assess the full influence of the 2-dose
