In Pakistan, the CIA collaborated with a senior government doctor named Shakil Afridi, who is now under arrest for collaborating with foreign agents, according to the Guardian. Health workers under his direction allegedly announced free hepatitis B vaccinations in March and set up a clinic in a poor neighborhood in Abbottabad „to make it look more authentic,“ the Guardian reported. After the first of the three-part vaccination series was given, the clinic was moved closer to the inner part of Abbottabad where the Bin Laden compound was located. At one point, nurses entered the Bin Laden compound to administer the vaccinations, carrying electronic recording devices, but it‘s unclear how successful they were in obtaining DNA.
