Some critics of PEPFAR feel that American political and social groups with moral rather than public health agendas are behind several requirements of PEPFAR, pointing to the mandates that one-third of prevention spending in 2006–2008 be directed towards abstinence-until-marriage programs and that all funded organizations sign an anti-prostitution pledge. This pledge requires all organizations that receive PEPFAR funding to have a policy that explicitly opposes prostitution and sex trafficking which some activists compared to a loyalty oath. A number of AIDS organizations felt such a policy would alienate their efforts to reduce HIV contraction rates among sex workers.
