What is mumps virus vaccine (Mumpsvax)?

Mumps is a serious diseases caused by a virus. It is spread from person to person through the air.

The mumps vaccine is used to help prevent this disease in children.

This vaccine works by exposing your child to a small dose of the virus or a protein from the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Measles, mumps, and rubella vaccine is for use in children who are at least 12 months old.

Like any vaccine, the mumps vaccine may not provide protection from disease in every person.

  • extreme drowsiness, fainting;
  • fussiness, irritability, crying for an hour or longer;
  • easy bruising or bleeding, weakness;

What is the most important information I should know about this vaccine (Mumpsvax)?

The mumps vaccine is usually given as one shot, followed later by a booster vaccine with measles, mumps, and rubella (MMR) vaccine. The first mumps vaccine is usually given when the child is 12 to 15 months old. The MMR shots are then given before the child starts elementary school. Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.

Be sure your child receives all recommended doses of this vaccine. If your child does not receive the full series of vaccines, he or she may not be fully protected against the disease.

Your child can still receive a vaccine if he or she has a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.

Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects your child has after receiving this vaccine. If the child ever receives a booster dose, you will need to tell the doctor if the previous shots caused any side effects.

Becoming infected with mumps is much more dangerous to your child's health than receiving the vaccine to protect against it. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.
