(CNN) – It was part of the plan to capture the world's most wanted man. In order to find Osama bin Laden, sources tell CNN, the CIA enlisted the help of Pakistani doctor Shakil Afridi to vaccinate locals for hepatitis, with the goal of secretly collecting DNA from the suspected bin Laden compound.
The program did not end up helping the CIA, agents were never able to get access to anyone in the compound, sources say.
But health care workers say the people of Pakistan, and the aid workers there to help them, are now paying the price.
The Taliban had been attacking health care workers before bin Laden's death in 2011, but since the revelation about Afridi, the Taliban have been given a new propaganda talking point: Immunizations could be part of another CIA plot.
Polio is now blowing up in the region; of the 77 new cases in the world this year, 61 are in Pakistan, according to the World Health Organization.
This week, Yahoo News reported that the White House has promised that the CIA will never again use immunizations as a ruse. But is that enough to undo the damage?
Yahoo News' White House correspondent Olivier Knox, who broke the story, and former CIA and FBI official now with the New America Foundation weigh in.
