Measles prevention

These revised recommendations of the Immunization Practices Advisory Committee (ACIP) on Measles Prevention replace previous recommendations published in 1987 (1) and 1989 (2). The recommendations include a basic change in the routine childhood vaccination schedule from a one-dose to a two-dose schedule using combined measles-mumps-rubella (MMR) vaccine. Routine revaccination will generally be implemented one age group at a time starting with school enterers. New recommendations are also included for vaccination of preschool children at high risk of contracting measles, for students in colleges and other institutions of higher education, for health-care personnel and international travelers, and for outbreak control.
