The CIA says that it will no longer use vaccination campaigns as a cover for intelligence programs, as it did several years ago when investigating Osama bin Ladens potential presence in his Abbottabad compound, reports Yahoo News. The agency saw backlash after details of the operation were revealed, as those programs already faced opposition in key regions and began to see even less acceptance as well as deadly attacks on health workers following the revelation. This CIA policy applies worldwide. The letter attempts to fully distance the CIA from vaccination campaigns, explaining that it would not make use of the programs or their workers. Similarly, the agency will not seek to obtain or exploit DNA or other genetic material acquired through such programs, Lisa Monaco, President Obamas homeland security advisor, writes in the letter. This CIA policy applies worldwide and to US and non-US persons alike.
