Study finds serious reactions to MMR vaccine are rare

December 12, 2011

New research led by Dr. Kumanan Wilson shows that children are more likely to show up in emergency rooms one to two weeks after getting their first measles, mumps and rubella vaccine shot, however in the vast majority of cases, these reactions are self-limited and likely represent a normal immune reaction to the vaccine. Dr. Wilson and his team came to this conclusion after analyzing data from more than 350,000 children who received the vaccine. Using the ICES@uOttawa facility, they were able to link the vaccination records for children in Ontario with their emergency room visits. See PLoS ONE for details.
