Measles-mumps-rubella vaccine gives extra bonus

In a Danish register-based study we found that MMR vaccination was associated with a 22% reduced rate of hospital contacts related to laboratory-confirmed infection with respiratory syncytial virus (RSV).

RSV is an important cause of childhood infections and hospitalisations, but we have no good vaccine against it so far. Thus, the non-specific effect of MMR on this virus is an added value of MMR.
