What are the percentages of adverse reactions to MMR? What is the fatality rate?
What are the health affect of a male catching the mumps later in life?
Do we set aside the polio vaccine as well.
Measles, Mumps, and Rubella (MMR) Vaccine
The mumps virus usually causes swelling in glands just below the ears, giving the appearance of chipmunk cheeks. Before the vaccine, mumps was the most common cause of both meningitis (inflammation of the lining of the brain and spinal cord) and acquired deafness in the U.S. In men, mumps can infect the testicles, which can lead to infertility.
Rubella is also known as German measles. It can cause a mild rash on the face, swelling of glands behind the ears, and in some cases, swelling of the small joints and low-grade fever. Most children recover quickly with no lasting effects. But if a pregnant woman gets rubella, it can be devastating. If she's infected during the first trimester of pregnancy, there's at least a 20% chance her child will have a birth defect such as blindness, deafness, a heart defect, or mental retardation.
