In a public health piece on measles, Howard Shapiro and Erica Weir state “The second dose [of measles vaccine or measles, mumps and rubella vaccine] should be given at least 3 months after the first.”1 I have reviewed all of the references listed for the article and each one clearly states that the second dose should be given at least 1 month (minimum 28 days) after the first.
