What are measles, mumps and rubella (MMR)?
The measles virus causes fever, cough, runny nose, pink eye and rash. If the measles virus infects the lungs, it can cause pneumonia. Some older children infected with the virus will suffer from brain inflammation, which can cause seizures and permanent brain damage.
The mumps virus usually causes fever, headache and swollen glands. It can lead to deafness, meningitis, painful swelling of the testicles or ovaries and, in some cases, death.
Rubella, also known as German measles, causes rash, low-grade fever and arthritis. If a pregnant person gets rubella, they could miscarry or give birth to a baby with serious birth defects.
