In this article, we evaluated vaccine-related parotitis and orchitis cases in healthcare workers after measles-mumps-ru-bella (MMR) vaccine containing Edmonston-Zagreb measles, Leningrad-Zagreb mumps and Wistar Ra 27/3 measles strains. Twelve mumps seronegative healthcare workers developed parotitis and orchitis after the MMR vaccine containing L-Z mumps strain. The cases were confirmed serologically with mumps IgM positivity.
