Evaluation of a combined vaccine against measles-mumps-rubella produced on human diploid cells.
The combined Measles-Mumps-Rubella vaccines commercially available for use are safe, highly immunogenic, and protective. But the acceptance rate of these vaccines by the public and also by the general practitioners in most part of Europe is not a very high one. One of the reasons for this low acceptance-rate is the fear of side-reactions. In spite of that only exceptional cases of dangerous allergic reactions induced by such vaccines, especially the lay population can be scared by the contraindications mentioned in the "physician circular-patent product information". Therefore it was worthwhile to test a new trivalent vaccine produced exclusively on human tissue without using any avian protein or animal protein extracts or antibiotics. Under double-blind conditions 120 children aged between 15 and 24 months received either the new vaccine or the commercially available M-M-R-II vaccine produced by MSD. Measles and Rubella antibodies were tested by hemagglutination-inhibition tests, Mumps by the immuno-fluorescence technique. No reports of major side-effects were received from the 12 physicians participating in the trial. The seroconversion rates recorded 6 to 8 weeks after vaccination were high (95-100%) and there was no statistically significant difference between the two vaccines with regard to immunogenic potency.
