If more states and school districts require two-dose varicella vaccination for school entry, it help further the Healthy People 2020 target of 95 percent of U.S. kindergarten students receiving two doses of varicella vaccine. A team of researchers, including those from the Centers for Disease Control and Prevention, compared the number of states that required two-dose varicella vaccination for elementary school entry in 2012 with the number in 2007. They also compared two-dose varicella vaccination coverage during 2006 with coverage in 2012 among children aged seven years. The number of states (including the District of Columbia) with a two-dose varicella vaccination requirement increased from four in 2007 to 36 in 2012. Coverage levels among seven-year-old children at six sites increased from a range of 3.6 percent to 8.9 percent in 2006 to a range of 79.9 percent to 92.0 percent in 2012. The increases suggest that there has been significant progress in implementing routine two-dose varicella vaccination programs since the Advisory Committee on Immunization Practices recommended it.
