MMR vaccine

The MMR vaccine is a vaccine against measles, mumps, and rubella (German measles).
The first dose is given to children around 9 to 15 months of age, with a second dose at 15 months to 6 years of age, with at least 4 weeks between the doses. After two doses 97% of people are protected against measles, 88% against mumps, and at least 97% against rubella. 
The vaccine is also recommended in those who do not have evidence of immunity, and those with well controlled HIV/AIDS. It is given by injection.
