What was discovered

Isolation of a retrovirus (LAV/HTLV-III) from patients' lymph nodes and demonstration that it causes acquired immunodeficiency. It enabled blood testing and the development of antiretrovirals.

The Gallo-Montagnier priority dispute over the origin of the samples was settled between the United States and France in 1987; the 2008 Nobel Prize went to Montagnier and Barré-Sinoussi.

What it led to

  • screening tests and safe transfusions
  • combination antiretroviral therapy (1996), which turned AIDS into a chronic disease
  • patient activism and changes in drug regulation
  • PrEP and prevention
