The White House has pledged to never again use polio vaccination campaigns as a front for CIA spying, as it infamously did during the 2011 search for Osama Bin Laden in polio-stricken Pakistan, Yahoo News reported Monday.

"I wanted to inform you that the Director of the Central Intelligence Agency (CIA) directed in August 2013 that the agency make no operational use of vaccination programs, which includes vaccination workers," Lisa Monaco, President Obama's top counterterrorism and homeland security adviser, wrote in a May 16 letter to the deans of 12 public health schools, according to Yahoo News.

"Similarly, the Agency will not seek to obtain or exploit DNA or other genetic material acquired through such programs," Monaco continued. "This CIA policy applies worldwide and to U.S. and non-U.S. persons alike."
