Early life exposures to toxic chemicals such as PCBs and DDT dampen an infant's response to the tuberculosis vaccine, according to a new study.
DDT? Banned over 40 years ago but so safe the United States EPA creates guidelines for other countries to spray it inside homes?
It's that pesky 'persistent pollutant' designation which, like endocrine disruptor, is invoked when nothing else is available. Todd Jusko, Ph.D., an assistant professor in epidemiology at the University of Rocheste, lead author of the paper, also says PCBs - banned in the 1970s - are still impacting babies and, in case that doesn't get environmental activist fundraiser juices flowing, that thousand of other pollutants similar to PCBs and DDT have "unknown health implications."
