Another huge study of over 650,000 kids shows absolutely no link between vaccines and autism. Doctors say it’s proof we’re living in a ‘fact-resistant’ world.

• A huge new study of more than 650,000 people in Denmark shows no link between the measles, mumps, rubella (MMR) vaccine and autism.

A massive new study from Denmark found no association between being vaccinated against measles, mumps, and rubella and developing autism.

In science and public health circles, that issue has long since been considered settled, with multiple studies over many years discounting the findings of a small study published more than 20 years ago that has since been expunged from the medical literature.

But the size of this study — involving 657,461 Danish children born between 1999 and 2010 — should, in theory, bolster the argument that doctors and public health professionals still fin themselves forced to make in the face of entrenched and growing resistance to vaccination in some quarters.

The work, published Monday in the Annals of Internal Medicine, was conducted by researchers at the Statens Serum Institut in Copenhagen. Some of the same scientists published an earlier article on this topic in the New England Journal of Medicine in 2002, based on data from 537,303 Danish children born between 1991 and 1998.

Why redo the work? Because the misplaced concern hasn’t gone away, said Anders Hviid, one of the researchers involved in the study.
