( CNN ) -- A Pakistani judicial commissioner has overturned the conviction of a doctor who is accused of helping the United States find Osama bin Laden , and has ordered a new trial , the official 's office said Thursday . Dr. Shakil Afridi will remain in prison until the new trial is held , according to the office of Sahibzada Mohammad Anees , the Peshawar judicial commissioner who overturned the conviction . Afridi was sentenced in 2012 to 33 years in prison after a tribal court convicted him of , among other things , running a fake vaccination trial . Pakistani authorities accused Afridi of working with the CIA to set up a fake vaccination campaign in Abbottabad to try verify bin Laden 's whereabouts . U.S. special forces killed the al Qaeda leader at an Abbottabad compound in May 2011 . Afridi had appealed the conviction . Information on why Anees granted the appeal was n't immediately available . Afridi 's attorney , Samiullah Afridi , said Thursday he expects the retrial to begin within a month . The doctor 's family has had no contact with him for nine months , the lawyer said . The vaccination effort , according to allegations in a report filed with a Pakistani appeals court , was meant to collect bin Laden 's DNA so the CIA could compare it with samples of bin Laden family DNA it already had , but no one at his Abbottabad compound agreed to be vaccinated . The report alleged that Afridi admitted receiving $ 75,800 from handlers for the vaccination effort . In 2012 , senior U.S. officials told CNN that Afridi worked with the United States prior to the bin Laden raid , but was never asked to spy on Pakistan and was asked only to help locate al Qaeda terrorists posing a threat to both Pakistan and the United States . After Afridi 's conviction , then-U.S. Secretary of State Hillary Clinton and then-U.S. Defense Secretary Leon Panetta called for his release . Clinton said Afridi `` was instrumental in taking down one of the world 's most notorious murderers . '' CNN 's Reza Sayah , Elise Labott and Jason Hanna , and journalist Annabel Symington contributed to this report .
