Measles, Mumps, and Rubella

What is Measles?

Measles is a disease caused by measles virus. Common symptoms include fever, cough, and rash.

20% of unvaccinated people who get measles need to be hospitalized. Measles can also cause pneumonia and encephalitis.

Two doses of the vaccine prevents 97% of measles infections, and the 3% of people who can still get infected have milder symptoms.

From 2000 to 2015, measles vaccination saved more than 20 million lives worldwide.

Mumps is a disease caused by mumps virus.

Common symptoms include swollen cheeks and jaw, fever, loss of appetite, and muscle aches.

Two doses of the vaccine prevent approximately 88% of mumps infections. Infections in vaccinated people usually have much milder symptoms.

Rubella is a disease caused by rubella virus.

Common symptoms include a rash, fever, headache, cough, and pink eye.

Getting rubella during pregnancy can cause miscarriages and birth defects.

2 doses of the vaccine provide almost 100% immunity against rubella infections.

Both vaccines provide protection against measles, mumps, and rubella, but MMRV also protects against varicella (chickenpox).
