To alleviate them a smidgen? The CIA did commit fraud with respect to vaccines a little while ago.
They posed as vaccinating doctors (and they actually **did** administer real vaccines), but were secretly gathering intelligence on the whereabouts of Al Queida and other would-be terrorists.
Alas, they couldn't keep this secret, and what they were doing -- leaked.
Now, the locals have an excellent excuse to distrust would be purveyors of vaccines....!
Horrid consequence-- but the CIA's never been real good at seeing the consequences of their insipid stupidity.
And yet the children are crippled.
