Health Concerns and the MMR Vaccine, December 1999

A number of recent scientific studies have investigated possible adverse health effects in infants receiving the MMR (Measles, Mumps and Rubella) vaccine. The studies focus on the question of whether measles-containing vaccines, including MMR, are associated with the onset of intestinal complaints and/or behavioural disorders. This briefing summarises the evidence from such studies and examines the issues that arise.
