This medication belongs to a group of medications known as vaccines. It is used in children to prevent measles, mumps, rubella, and chicken pox by increasing your defenses against the viruses that cause these illnesses. Vaccines do not cause the illness they are protecting against. This vaccine works by introducing very small amounts of weakened versions of the viruses. The weakened viruses stimulate the production of a person’s own antibodies (molecules designed to attack that particular virus or toxin). The cells that produce antibodies remain in the body, ready to attack any future viruses that cause infection.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: The measles and mumps components of this vaccine are produced in chick embryo cell culture and may contain traces of egg protein. If your child has had an allergic reaction to egg in the past, be sure to tell your child’s doctor.
Your doctor may ask you and your child to stay in the office for about 30 minutes after having the vaccine so you can receive medical care if an allergic reaction occurs. If you notice signs of a severe allergic reaction in your child (hives; trouble breathing or swallowing; or swelling of the lips, face, throat, or tongue), get medical attention immediately.
Immune system: As with any vaccine, this vaccine may not be as effective for people with a weakened immune system (such as people who are on chemotherapy, have had an organ transplant, or have HIV).
If your child has a weakened immune system for any reason, discuss with your doctor how this medication may affect your child’s medical condition, how your child’s medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infection: Your child’s doctor may decide to delay this vaccine if your child has an acute infection or fever. Mild infections without fever, such as colds, usually do not require delay of the vaccine.
Medical conditions: Varicella vaccine should not be given for at least 3 months following a blood or plasma transfusion or human immunoglobulin therapy.
Seizures: There is an increased risk of seizures due to fever after receiving a vaccine for measles. Fever is a common side effect of this vaccine. Discuss appropriate treatment of fever with your doctor and make sure you know when it is necessary to get medical help for your child. Your child’s doctor may suggest that you give your child a dose of medication to prevent fever.
Vaccine protection: As with any vaccine, this vaccine may not protect all people who receive it.
Pregnancy: This medication should not be used by women who are or may be pregnant. Pregnancy should be avoided for three months following vaccination.
Breast-feeding: This medication is intended for children under the age of 12 years. As such, it should not be used by women who are breast-feeding.
