> I don't think anyone has ever seriously suggested that the CIA has tampered with the vaccines. They merely co-opted the inoculation process in order to gain a biological sample.
Its not about CIA tampering with the vaccines. The assumption was that the vaccination programs were politically neutral, a system meant to better humanity regardless of politics or military targets etc etc and in many places, that's what was said to convince people on the ground.
Unfortunately, the use of a doctor to aid in information gathering for the CIA in a vaccination campaign means that that assumption is completely gone.
The context is that the Pakistan and Afghanistan border region is the only place in the world where polio still spreads, while the rest of the world it has been eradicated.
However, there is already suspicion due to lack of education and literacy that the vaccine is some sort of Western plot. So all this did was ensure that there continue to be attacks on polio and other vaccination workers in the area by 1. terrorist groups which was happening anyway, but 2. by uneducated paranoid people who think that the vaccine has been the "plot" of the western governments to do something bad to them.
All in all, the CIAs use of a charity organisation and a vaccination drive as a front for its activities has basically led to hundreds being affected by polio, unable to live their lives in good health or even in death.
