"The deans of the nation's top public health schools sent a letter to President Obama on Monday condemning the Central Intelligence Agency's use of a vaccination campaign ruse in the hunt for Osama bin Laden," the New York Times reports, noting, "The letter was signed by deans at Columbia, Harvard, Johns Hopkins and nine other universities." According to the newspaper, "[t]he CIA has admitted hiring a Pakistani doctor to give out hepatitis B vaccine, apparently in an effort to get DNA samples from the compound that it suspected was Bin Laden's hide-out," which "has caused a severe backlash against vaccination in Pakistan" (McNeil, 1/7).
