School entry requirements in increasing numbers of states have helped boost 2-dose varicella vaccination rates among US children, according to a recent analysis.
The school requirements went into wider use after the Advisory Committee on Immunization Practices’ (ACIP) 2007 recommendation that children aged 4 to 6 years receive a second dose of varicella vaccine. Using data from state immunization websites, the analysis showed that the number of states (including the District of Columbia) with a school entry requirement increased from 4 in 2006, before ACIP’s recommendation, to 36 in 2012 (Lopez AS et al. MMWR Morb Mortal Wkly Rep. 2014;63:174-177).
