That story doesn't say that the vaccine infected anybody.
It said that they gave a study group of men and transgender men who routinely had man-to-man sex a "vaccine". Half were given a placebo and half were given the vaccine.
At the end of the study the vaccine was considered a failure because slightly more men on the vaccine contracted HIV as opposed to the placebo group.
