Short-Term Vaccine Against AIDS Ruled Out

A leading French scientist has ruled out any hope of developing a short-term vaccine against HIV/AIDS in the short term.

“The development of a preventive or therapeutic vaccine against HIV has still a long way to go and is certainly one of the most difficult challenges facing the world's scientific community today," Xinhua quoted Jean-Francois Delfraissy, director of France's National Agency for Research on AIDS and Viral Hepatitis (ANRS), as telling reporters in the Senegalese capital of Dakar on May 27.

“Since the first ever vaccine trial was launched, over 80 phases I and II have been conducted mostly in Europe and the United States and one clinical trial has even gone as far as phase III, but without much success being recorded.

“A series of quarantine tests are under study and among them is a vaccine that the ANRS has been developing under the past ten years," according to the French researcher who called for increased efforts against the disease.

"Clinical research must continue to develop new therapeutic strategies within the framework of trials that should be conducted in accordance with good clinical practices, dialogue and partnership with the civil society and the pharmaceutical industry," said Delfraissy.

The professor added: "We must continue to move forward in our search for a better understanding of immune mechanisms, improve available vaccine candidates, assess their tolerance and immunogenicity using clinical trials."
