Vaccine induced mumps-like diseases.

Sixteen cases of parotitis and 2 cases of diabetes mellitus after mumps vaccination have been reported since the introduction of the live attenuated mumps vaccine in the F. R. Germany in the fall of 1976. Due to the post-vaccination incubation of 7 to 10 days, support is given to the assumption that these cases are vaccine induced and not coincidental wild virus infections. The diabetes mellitus cases, however, are too few to be included in this rational.
