Reports of sensorineural deafness after measles, mumps, and rubella immunisation

Abstract

There have been nine reports of sensorineural hearing loss after measles, mumps, and rubella (MMR) immunisation. In three cases the deafness was unrelated to MMR immunisation. In six cases the cause was unknown and MMR remained a possible aetiology. Any risk associated with attenuated viruses must be weighed against the risks of the natural diseases.
