The Measles, Mumps, and Rubella (MMR) Vaccine

The measles, mumps, and rubella (MMR) vaccine was created by Maurice Hilleman in 1971 at the Merck Institute of Therapeutic Research, a pharmaceutical company in West Point, Pennsylvania. It combined three separate vaccines for measles, mumps, and rubella, common and sometimes fatal diseases. Measles causes a red skin rash and severe fevers that can be fatal. Mumps causes fever and swelling of the salivary glands in the mouth and jaw, while rubella causes milder fevers and skin rashes. Pregnant women that contract rubella sometimes pass the virus to their fetuses, causing congenital rubella syndrome, which results in malformations of the eyes, ears, heart, and brain in the fetuses. The MMR vaccine has protected millions of people from contracting the potentially deadly diseases of measles, mumps, and rubella, as well as prevented the development congenital rubella syndrome in the fetuses.
