A Field Trial of Combined Measles- Mumps-Rubella Vaccine

Abstract
This report presents confirming evidence for the immunizing value of a trivalent combined measles-mumps-rubella vaccine (M-M-R), based on studies with 188 children in Chile. All of the children de veloped antibody against measles virus and 96 per cent developed antibodies against mumps and rubella. No clinical reaction occurred other than that expected to follow measles vaccine given alone.
