Researchers of the HVTN 702 study in South Africa, which began in 2016 to create a HIV vaccine, announced earlier this year that they have stopped administering vaccinations in clinical trials.
The promising HIV vaccine wasn’t showing negative side effects or safety issues in the clinical trials. The vaccine failed because it wasn’t proving to be effective against HIV.
“An HIV vaccine is essential to end the global pandemic, and we hoped this vaccine candidate would work. Regrettably, it does not,” said Dr. Anthony Fauci, infectious disease chief of the National Institutes of Health (NIH).
