The Use of School-Based Vaccination Clinics to Control Varicella Outbreaks in Two Schools

School-based vaccination clinics were offered in 2 schools experiencing varicella outbreaks. The clinics raised coverage of susceptible children from 52.9% to 92.2% and from 68.8% to 85.3% in the 2 schools, respectively.
