Immunity to measles in the United States among a) children aged 19 to 35 months and b) adolescents aged 13 to 17 years for all 50 states and the District of Columbia from the 2012 National Immunization Surveys (http://www.cdc.gov/vaccines/imz-managers/coverage/nis/child/2012-released.html). Immunity was estimated as proportions of children with at least one and adolescents with two or more doses of MMR vaccine times efficacies of 92% and 95%, respectively. The curves are fitted beta distributions having shape parameters α = 208.39 and β = 40.65 for children and α = 83.98 and β = 12.52 for adolescents. Insofar as some adolescents have had one dose of MMR, figure 1b under-estimates their immunity to measles.
