Brainerd Dispatch

"An Associated Press examination of states' vaccination records and data from the Centers for Disease Control and Prevention found that many states are seeing increases in the rate of religious exemptions claimed for kindergartners. 'Do I think that religious exemptions have become the default? Absolutely,' said Dr. Paul Offit, head of infectious diseases at Children's Hospital in Philadelphia and one of the harshest critics of the anti-vaccine movement. He said the resistance to vaccines is 'an irrational, fear-based decision.'" (10/17/07)
