Although the 1-dose varicella vaccination program, introduced in 1996, has led to significant declines in varicella disease, outbreaks continued to occur, which led to the adoption of a 2-dose vaccination program in 2007. We previously reported an 88% decline in varicella-related hospitalizations and a 59% decline in outpatient visits during 1994-2002. We now update data on varicella healthcare utilization with 10 years of additional data, during a period of stabilizing first-dose coverage and rapidly increasing second-dose coverage.
