The Vatican returned to the contentious issue of HIV/AIDS prevention at a conference sponsored by the Pontifical Council for Health Care Workers. One hundred invited experts ranged from theologians to doctors. Speakers included Michel Sidibe, the executive director of UNAIDS, and Cardinal Tarcisio Bertone, the Vatican's Secretary of State.
Another participant was Edward C. Green, an American AIDS expert who generated a lot of attention when he defended Pope Benedict's comments on condoms
in 2009. In an interview with Catholic News Service, Green explains why promoting abstinence and monogamy is more effective at preventing the spread of the disease than widespread condom distribution.
