From MSNBC: The World Health Organization and the U.N. agency UNAIDS said the results “instilled new hope” in the field of HIV vaccine research, although researchers say it likely is many years before a vaccine might be available.

Obviously this is incredible news. The trial was over 16,000 patients and the new vaccine trial prevented HIV from infecting 31%. An HIV vaccine would be an amazing achievement for medial science. I only wish people’s behavior would make the necessary preventative measures as well.
