A system intended to speed help to vaccine-injured Americans has instead heaped additional suffering on thousands of families. To investigate vaccine court in depth, the AP read hundreds of decisions, conducted more than 100 interviews, and analyzed a database of more than 14,500 cases. Among the AP's findings: * Prominent attorneys have enlisted expert witnesses whose own work has been widely discredited, including one who treated autism with a potent drug used to chemically castrate serial rapists. Some of the most prominent experts set up nonprofits questioning vaccine safety. Many doctors hired by the government to defend vaccine safety in court have ties to the pharmaceutical industry. * The government fights legitimate claims ... worried that if they concede a vaccine caused harm, the public will react by skipping shots. If government doctors had their way ... 1,600 families would not have gotten more than $1.1 billion in cash and future medical care between the court's opening in 1988 and then end of 2012. * Cases are supposed to be resolved within 240 days. Less than 7 percent of 7,876 claims not involving autism met the 240-day target. Most non-autism cases take at least two and a half years. Hundreds have surpassed the decade mark. Several people died before getting any money. The system is not working," said Richard Topping, a former U.S. Department of Justice attorney who handled vaccine injury claims but resigned after concluding his bosses had no desire to fix the major flaws he saw.
