title: Pertussis vaccine performance in an epidemic year-Oregon, 2012.
abstract: A 2012 pertussis epidemic in Oregon afforded an opportunity to measure vaccine effectiveness; it ranged from 95% (95% confidence interval [CI], 92%-97%) among children 15-47 months of age to 47% (95% CI, 19%-65%) among adolescents 13-16 years of age. In all age groups, pertussis incidence was higher among unimmunized persons.
