An article in this week's New England Medical Journal, one more trying to determine how much danger, thimerosal in vaccines poses to children apparently finds no causal link. The problem is the weasel-words, circumlocutions and bad prose used to state the conclusion as well as the poor judgement of the study designers by including so epidemiologists with ties to Merck and other pharmaceutical companies in the study. While the study may have been free of bias it gives the perception of having been designed to favor the vaccine makers, and will not help when the issue go to court. This study has not done good service to the case for prevention.
