A Scientist’s Danish Cohort Study Rebuttal
The MMR vaccine study recently published by Hviid et al. (2019, Annals of Internal Medicine) entitled, “Measles, Mumps, Rubella Vaccination and Autism: A Nationwide Cohort Study,” leaves many more serious questions than definitive answers.
The authors claim that their work, “strongly supports that MMR vaccination does not increase the risk for autism, does not trigger autism in susceptible children, and is not associated with clustering of autism cases after vaccination.”
This is an extremely broad claim that unfortunately is not supported by the evidence they present. There are eight fundamental flaws in the research study that lead to questions about the accuracy of the conclusions.
