Since first identified in 2016, more than 30,000 cases with over 60% hospitalizations and at least 300 deaths have been reported. One dose of single-antigen hepatitis A vaccine has been shown to control outbreaks of hepatitis A — and provides up to 95% seroprotection in healthy adults. www.cdc.gov/hepatitis/HepAOutbreak FactSheet-HepAOutbreakWhatClinicansCanDo.pdf
