This is a summary of information about M-M-R II*. You should read it before you or your child receives the vaccine. If you have any questions about the vaccine after reading this leaflet, you should ask your health care provider. This is a summary only. It does not take the place of talking about M-M-R II with your doctor, nurse, or other health care provider. Only your health care provider can decide if M-M-R II is right for you or your child.
What is M-M-R II and how does it work?
M-M-R II is also known as Measles, Mumps, and Rubella Virus Vaccine Live. It is a live virus vaccine that is given as a shot. This vaccine is usually given to people one year old or older. It is meant to help prevent measles (rubeola), mumps, and rubella (German measles).
M-M-R II contains weakened forms of measles virus, mumps virus, and rubella virus.
M-M-R II works by helping the immune system protect you or your child from getting measles, mumps, or rubella.
M-M-R II may not protect everyone who gets the vaccine. M-M-R II does not treat measles, mumps, or rubella once you or your child has them.
What do I need to know about measles, mumps, and rubella?
Measles is also known as rubeola. It is a serious illness. Measles virus can be passed to others if you have it. Measles can give you a high fever, cough, and a rash. The illness can last for 1 to 2 weeks. In rare cases, it can also cause an infection of the brain. This could lead to seizures, hearing loss, mental retardation, and even death.
Mumps can also be passed to others. This virus can cause fever and headache. It also makes the glands under your jaw swell and be painful. The illness often lasts for several days. Sometimes, mumps can make the testicles swell and be painful. In some cases, it can cause meningitis, which is a mild swelling of the coverings of the brain and spinal cord.
Rubella is also known as German measles. It is often a mild illness. Rubella virus can cause a mild fever, swollen glands in the neck, pain and swelling in the joints, and a rash that lasts for a short time. It can be very dangerous if a pregnant woman catches it. Women who catch German measles when they are pregnant can have babies who are stillborn. Also, the babies may be blind or deaf, or have heart disease or mental retardation.

How is M-M-R II given?
M-M-R II is given as a shot to people one year old or older. 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.
If a dose is missed, your health care provider will let you know when you should have it.
Non-pregnant adolescent and adult females of childbearing age who are susceptible to rubella can be vaccinated with M-M-R II (or live attenuated rubella virus vaccine) if certain precautions are taken. In many cases, it is convenient to give the vaccine to women at risk for rubella right after they give birth.
