Jan. 19, 2023 – The only HIV vaccine nearing the completion of testing trials is not effective at preventing HIV, officials announced Wednesday.
The vaccine had been in development since 2019 and was given to 3,900 study participants through October 2022, but data shows it does not protect against HIV compared to a placebo, according to developer Janssen Pharmaceutical .
Experts estimate the failure means there won’t be another potential vaccine on the horizon for 3 to 5 years, The New York Times reported .
“It’s obviously disappointing,” Anthony Fauci, MD, former head of the National Institute of Allergy and Infectious Diseases, told MSNBC , noting that other areas of HIV treatment research are promising. “I don’t think that people should give up on the field of the HIV vaccine.”
No safety issues had been identified with the vaccine during the trial, which studied the experimental treatment in men who have sex with men or with transgender people.
