From 1946 to 1948, American and Guatemalan physicians infected prostitutes and prisoners with syphilis without their knowledge or consent in order to test penicillin. The research was discovered by a Wellesley College professor in 2009, and lawyers for the victims filed a class-action lawsuit against the United States. The Obama administration claims that the US is immune from such lawsuits, but has announced that it will spend $1 million to review new rules to protect medical research volunteers, $775,000 to fight sexually transmitted diseases in Guatemala, and will develop a system to compensate anyone harmed in medical research. Lawyers for the Guatemalan victims say that the promised action is inconsistent with the claim of immunity. [Washington Post]
