Second-dose varicella vaccination coverage in children and adolescents in a managed care organization in California, 2006-2009

Pediatr Infect Dis J. 2011 Aug;30(8):705-7. doi: 10.1097/INF.0b013e31820eae6a.


We assessed trends of second-dose varicella-containing vaccine coverage among children and adolescents in Kaiser Permanente Southern California health plan since the Advisory Committee on Immunization Practices recommendation of 2-dose varicella vaccination in 2006. The overall second-dose coverage increased rapidly from 42.1% in 2007 to 74.6% in 2009. The increasing trend was observed in all strata defined by age and race/ethnicity, with the highest coverage among children aged 5 to 6 years old. However, non-Hispanic White race/ethnicity and living in a neighborhood with higher education level were inversely associated with the second-dose uptake.
