Mmrv Vaccine for Children


The MMRV vaccine is an injection given to help prevent measles, mumps, rubella, and varicella (chickenpox). These diseases are caused by viruses that spread easily from person to person. Measles, mumps, rubella, and varicella can cause serious, long-term health effects or become life-threatening. The vaccine may be given to children 12 months through 12 years of age.


Call your local emergency number (911 in the US) if:

  • Your child's mouth and throat are swollen.
  • Your child is wheezing or has trouble breathing.
  • Your child has chest pain or his or her heart is beating faster than usual.
  • Your child feels like he or she is going to faint.
  • Your child has a seizure.

Seek care immediately if:

  • Your child's face is red or swollen.
  • Your child has hives that spread over his or her body.
  • Your child feels weak or dizzy.

Call your child's doctor if:

  • Your child has a fever or chills.
  • Your child has swollen lymph glands in his or her cheeks or neck.
  • Your child's joints are painful and swollen.
  • Your child has increased pain, redness, or swelling around the area where the shot was given.
  • You have questions or concerns about your child's condition or the MMRV vaccine.

Apply a warm compress

to your child's injection area as directed to decrease pain and swelling.

Safety precautions:

  • Do not give aspirin for 6 weeks after a dose of MMRV or separate varicella vaccine. Aspirin and other salicylate medicines increase the risk for a serious condition called Reye syndrome after a varicella vaccine. Talk to your child's healthcare providers about safe medicines if needed to control a health condition.
  • If your child develops a rash, do not let him or her near anyone who is not protected against varicella. The rash may be caused by the varicella part of the MMRV vaccine, or from a separate varicella dose. Your child's healthcare provider can tell you when your child will no longer be able to spread varicella. This is usually after the rash goes away.

Follow up with your child's doctor as directed:

Write down your questions so you remember to ask them during your visits.
