In Search of New Ideas for Global Health

Abstract

The recent failure of another potential vaccine against human immunodeficiency virus (HIV) underscores the enormous challenges of tackling diseases whose heaviest burden falls on the developing world. A quarter of a century after the first report of AIDS, our knowledge about how an HIV vaccine might work is still distressingly limited. It seems clear that neither current dogma nor traditional thinking is likely to get us to the next step. Truly creative ideas will be required.
