M-M-R II is also known as Measles, Mumps, and Rubella Virus Vaccine Live, is a live virus vaccine, containing weakened forms of measles virus, mumps virus, and rubella virus.
It is indicated for simultaneous vaccination against measles (rubeola), mumps, and rubella (German measles).
This vaccine is usually given to people one-year-old or older.
M-M-R II is given as a shot administered subcutaneously, preferably into the outer aspect of the arm. The dose of the vaccine is the same for everyone.
If your child gets the shot when he or she is one year old or older, a second dose is recommended.
Often, the second dose is given right before the child goes to elementary school (4 to 6 years of age).
If your child is less than one year old when he or she first gets the shot, a second dose should be given when they are 12 to 15 months old.
Then, a third shot should be given between 4 and 6 years of age.
Your doctor will decide the best time and number of shots by using official recommendations.
M-M-R II works by helping the immune system protect you or your child from getting measles, mumps, or rubella.
Over its 32-year history, ∼575 million doses of M–M–R II have been distributed worldwide, with 17,536 AEs voluntarily reported for an overall rate of 30.5 AEs/1,000,000 doses distributed.
This review provides evidence that the vaccine is safe and well-tolerated.
