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.
There is no cure for HIV, but disease progression can be managed with existing treatments.

More than 1.5 million people worldwide were infected with HIV in 2021 and 38.4 million people are living with the virus, according to UNAIDS.
