The U.S. government licensed Merck’s measles, mumps, and rubella combination vaccine (M-M-R). In an article published in the Journal of the American Medical Association, researchers reported that the vaccine induced immunity to measles in 96% of vaccinated children; to mumps in 95%; and to rubella in 94%. Additionally, initial tests in 1968 had already shown that adverse reactions from the MMR vaccine were no greater than from any of the single vaccines.
