Vaccines

Timely vaccination during infancy has no adverse effect on neuropsychological outcomes 7 to 10 years later. These data may reassure parents who are concerned that children receive too many vaccines too soon.

From the late 1990s to the present, scientists have looked closely at the evidence, and every well-done study has pointed to the same conclusion: thimerosal in vaccines has no link to autism. In one very large Danish study, autism rates rose after thimerosal was removed from vaccines. Another study looking at California, Sweden, and Denmark found the same thing. These results directly contradict the claim that thimerosal causes autism.

Last Friday, a special vaccine court ruled on three cases in which parents were suing on behalf of their autistic children. In each case, the parents claimed that thimerosal had caused their child’s autism. In each case, the Special Master (a judge) ruled definitively against the parents. The result was a slam-dunk win for science.

More than any other research, it was a study published in the British medical journal the Lancet in 1998 that helped foster the persisting notion that childhood vaccines can cause autism. On Feb. 2, that flawed study, led by gastroenterologist Dr. Andrew Wakefield, was officially retracted by the journal's editors--a serious slap and a rare move in the world of medicine. "It has become clear that several elements of the 1998 paper by Wakefield et al. are incorrect, contrary to the findings of an earlier investigation," wrote the Lancet editors in a statement issued online.

British physician Dr. Andrew Wakefield has been branded a primary instigator of the mania that drove parents to avoid having their children undergo routine immunizations for fear that inoculations could produce autism. It was Wakefield's article, published in 1998 in the premier British medical journal, The Lancet, that gave authority to the proposition that combined inoculations for measles, mumps and rubella were connected to childhood autism.

The medical journal which originally published the discredited research linking autism and MMR has now issued a full retraction of the paper. The Lancet said it now accepted claims made by the researchers were "false".
