(Vatican Radio) Pope Francis has given the ‘thumbs up’ to the ground-breaking work of a leading Argentinian-Canadian doctor who pioneered the use of Antiretroviral drugs to treat and prevent HIV infections. Dr Julio Montaner, who is director of the British Colombia Centre for Excellence in HIV-AIDS and a special advisor to the UNAIDS programme, met with the Pope and other top Vatican officials on Wednesday to seek support for the goal of extending the life-saving treatments to as many HIV-infected people as possible over the next five years.
