There's a war going on between those who believe in the health benefits of vaccines ... and those that believe that the immunizations do more harm than good. Now one of the authors of a 2004 government study that found similar vaccination rates among children with and without autism says the study omitted some important data. William Thompson, a senior scientist at the Centers for Disease Control (CDC) and one of the authors of a 2004 study published in the journal Pediatrics, spoke with Brain Hooker, who serves on the board of Focus Autism (which was founded to put an end to the needless harm of children by vaccination and other environmental factors"), about the data that was not included in the final report. Hooker and Thompson ... discussed a subset of the 624 children with autism and 1824 without the condition who were studied. Thompson admitted that among African-American boys, the incidence of autism was higher among those who were vaccinated than among those who weren't. But that information was not part of the paper. Did the CDC cover up the data? Thompson claims that the findings were statistically significant, but ... that the way that the 2004 study was presented does not negate the importance of vaccination, [and that] the risks associated with their administration are vastly outweighed by their individual and societal benefits.
