So as to not provide any more baseless evidence against vaccines under the guise of impartial reasoning, the CIA led vaccination drive actually did provide vaccines in a poorly developed region, but the data collected led to the capture of Bin Laden.
In and of itself, the vaccination drive wasn't some sort of hoax, and it had legitimate doctors and results. It had just been co-opted by the CIA for covert intelligence gathering.
That doesn't actually make it better. The point is that we want people in those communities to be able to trust that the doctors who come to their door don't have an ulterior motive. It's not a question of whether the vaccines are real (though faking that would of course have been far worse).
The misguided vaccine program in Pakistan was started in a poor neighborhood of Abbottabad, no doubt to give it an air of legitimacy. Yet after the first in a standard series of three hepatitis B shots was given, the effort was abandoned so that the team could move to bin Laden's wealthier community.
