  Researchers at Copenhagen's Statens Serum Institut examined data for Danish children born from 1999 through the end of 2010, more than half a million people altogether. The epidemiologists and statisticians then used population registries to link information on vaccination status to autism diagnoses, as well as to sibling history of autism and other risk factors.
  Omer nevertheless hailed the Danish paper as "the largest, or one of the largest, studies on the subject." Its only limitation, he said, was one basic to all observational studies, that "you can't intentionally vaccinate people or prevent them from vaccinating to study the effects, which would be unethical."
