A phony vaccination campaign orchestrated by the CIA to help find and kill Osama bin Laden is undercutting Western-backed immunizationdrives against polio and other diseases, and now has the Pakistani doctor involved in the program possibly facing treason charges.

A Pakistani government commission investigating the U.S. raid that killed Bin Laden in May recommended late Thursday that treason charges be filed against Dr. Shakeel Afridi, who helped carry out the fake vaccination effort designed to obtain DNA evidence from the Al Qaeda leader's sprawling compound in Abbottabad.

The ruse not only compounded Pakistan's anger toward America over the raid but also hampered efforts by Pakistani and Western aid organizations involved in real vaccination campaigns, a worrying development in a country where poor sanitation and lack of adequate healthcare aggravate the spread of disease.

Aid teams heading polio vaccination drives reported that more parents were refusing to allow their children to be vaccinated after news of the CIA ruse.
