While the nanoemulsion HIV vaccine showed promise in Baker’s study, says Amiji, mice are not a good model for HIV infection. The technology must stand up as well to testing in nonhuman primates and eventually humans. Amiji also cautions that the nanoemulsion tactic does not directly address one of the most vexing challenges in creating a vaccination for HIV: the virus’s rapid evolution.

That’s enough “buts” to lower my interest until the next piece of news appears.
