Girls more likely to visit hospital after MMR vaccine

February 5, 2014

Girls have an increased likelihood of reacting to the one-year MMR vaccine than boys, according to a large, Ontario population-based study by led Dr. Kumanan Wilson and published in Vaccine. The MMR vaccine is an immunization against measles, mumps and rubella that is typically given at 12 months of age. The findings suggest that there may be important physiological differences between boys and girls that cause different responses to the measles virus and measles-containing vaccines. See media release for details.
