> On May 16, 2014, the White House announced that the CIA will no longer use vaccination programmes as a cover for espionage. The news comes in the wake of a series of militant attacks on polio vaccination workers in Pakistan, with legitimate health-care workers targeted as being US spies. The attacks have forced organisations such as the UN to suspend polio vaccination efforts in Pakistan, and have severely hampered anti-polio efforts, with parents refusing to have their children vaccinated. News of the vaccination programme led to a banning of vaccination in areas controlled by the Pakistan Taliban, and added to existing scepticism surrounding the sincerity of public health efforts by the international health community.
