These are almost blind trials, figure it out : they take two strands of vaccine that did not work, combine them and try again. Now it has worked but scientist will have to understand what active component has managed to protect individuals. It's very impressive how hard it is to find a HIV vaccine.

It’s very impressive how hard it is to find a HIV vaccine.

He talked about the 2 vaccine components boosting either "the immune system and the white cells". Of course, white cells are part of the immune system. The 2 components primarily boost either antibody-producing B white cells (antibody can block infection of further cells and recruit other killer cells) or "cellular immunity" T cells (which directly kill infected cells). Also, he was quoted as saying "polio virus" wasn't in the vaccine. Of course it is not, he meant HIV was not in the vaccine, just inert protein components which cannot replicate like HIV. So the 2 components are completely safe, as he said. For this specialist niche issue, an HIV (preferably HIV vaccine expert), of which there are many in Boston as well as world-wide, might have made things clearer.
