Measles can be prevented by vaccination. Measles vaccine is administered at 6 months and 12 months of age. Measles vaccine is also available as a combination called measles, mumps, and rubella (MMR) vaccine in the private sector and in military health care facilities. MMR is usually administered at 12 months and 18 months. If a measles vaccine dose has been missed, it is never too late to catch up on a measles vaccination.
