A clinical trial for an HIV vaccine has been discontinued since the vaccine was not found to prevent infections of human immunodeficiency virus, the virus that causes AIDS.
"An HIV vaccine is essential to end the global pandemic, and we hoped this vaccine candidate would work. Regrettably, it does not," Dr. Anthony Fauci, director of the NIAID, said in a written statement on Monday.
"Whilst this is a significant setback for the field, we need to continue the quest for a preventive vaccine. The rates of HIV infection, which continue unabated in this region, should spur greater urgency, global attention and investment to the quest," Linda-Gail Bekker, immediate past president of the International AIDS Society and chair of the Enterprise Advisory Group, said in that separate announcement.
This trial wasn't the only investigation into approaches to prevent HIV. The National Institutes of Health has invested in two other late-stage, multinational HIV vaccine trails, both testing a novel vaccine regimen, among other HIV prevention trials.
