If you keep doing what you have always done, you will keep getting what you have always got. In the case of using NHPs to find a vaccine against HIV, that is precisely nothing.

Surely it is time to focus on trying more human biology-focused methods of testing potential vaccine candidates?

For example: an article in Time magazine on 27 March described VaxDesign's Modular Immune In vitro Construct. This enables researchers to test vaccine candidates on in vitro versions of the immune systems from hundreds of volunteers who have donated blood which contains peripheral blood mononucleocytes. This is a technology supported by the International AIDS Vaccine Initiative, and because it uses human material, it offers advantages that NHP-based tests simply cannot.
