Common side effects of M-M-R II include burning or stinging at the injection site for a short time.

The FDA categorizes medications and vaccines based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

M-M-R II falls into category C. No studies have been in animals, and no well controlled studies have been done in pregnant women.

Pregnant females should not receive M-M-R II vaccine since the possible effects of the vaccine on the development of the unborn baby are unknown at this time. Females of reproductive potential who receive M-M-R II vaccine, should avoid becoming pregnant for three months following vaccination. 

Tell your doctor is you are breastfeeding or plan to breastfeed. 

It is not known if M-M-R II crosses into human milk. Because some vaccines can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this vaccine, a choice should be made whether to stop nursing or stop the use of this vaccine. Your doctor and you will decide if the benefits outweigh the risk of using M-M-R II. 

• This vaccine will be administerd by a healthcare provider.
• M-M-R II is a vaccine that is injected just under the skin (subcutaneous) of the upper arm. 
• If a dose is missed, your health care provider will let you know when you should have it.

M-M-R II is a vaccine that is injected just under the skin (subcutaneous) of the upper arm. The recommended age for primary vaccination is 12 to 15 months.

If your child gets the shot when he or she is 12-15 months, 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.

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. 

Your doctor will decide the best time and number of shots by using official recommendations.

M-M-R II is administered by a healthcare provider in a medical setting. It is unlikely that an overdose will occur in this setting. However, if overdoes is suspected, seek emergency medical attention.
