A nationwide cohort study of all children born in Denmark to Danish-born mothers between 1999 and 2010 explored the link between the mumps, measles, and rubella (MMR) vaccine and autism.

Researchers found that the MMR vaccine does not increase the risk of autism, does not trigger autism in susceptible children, and is not associated with clustering of autism cases following vaccination.

Vaccine hesitancy is a top 10 global health threat

The hypothesised link between measles, mumps, rubella (MMR) vaccine and autism continues to cause vaccine hesitancy.

Currently, there is a concerning increase in measles cases in Europe and the U.S., and the World Health Organisation (WHO) has declared vaccine hesitancy as one of the top 10 threats to global health.

The study included over 650 000 children

Researchers from Statens Serum Institut, Copenhagen, Denmark used a Danish population registry to evaluate whether the MMR vaccine increases the risk for autism in children, subgroups of children, or time periods after vaccination.

Of the 657 461 children included in the analysis over a decade of follow-up, 6 517 were diagnosed with autism.

Comparing MMR-vaccinated with MMR-unvaccinated children yielded a fully adjusted autism hazard ratio of 0,93.

Similarly, no increased risk for autism after MMR vaccination was consistently observed in subgroups of children defined according to sibling history of autism, autism risk factors (based on a disease risk score) or other childhood vaccinations, or during specified time periods after vaccination.

According to the researchers, this study addresses questions about susceptible subgroups and autism clustering.
