In the report, “Lack of Measles Transmission to Susceptible Contacts from a Health Care Worker with Probable Secondary Vaccine Failure — Maricopa County, Arizona, 2015,” on page 833, the last sentence of the report, “2 doses of MMR vaccine, administered ≥28 days apart, are recommended for children aged ≥12 months and adults born after 1956, for prevention of measles,” should be replaced with the sentence: “All vaccine-eligible persons aged ≥12 months should receive the age-appropriate number of MMR vaccine doses unless they have other evidence of measles immunity.”
