Pablo Valenzuela, renowned Chilean scientist co-founder of Chiron Corporation and Fundación Ciencia & Vida, directed the research of Michael Houghton, a scientist who today received the Nobel Prize in Medicine.

Valenzuela, as Vice President of Research for Chiron, formed and led the team of researchers, including Michael Houghton, who identified the Hepatitis C virus, sequenced its genome, and developed tests for use in blood banks.

The Hepatitis C program, along with the Hepatitis B and AIDS virus, were part of Chiron’s overall strategy to study infectious diseases transmitted by blood transfusions. In addition to the development of the Hepatitis B vaccine, another of the important results of this company was the development of tests to identify these three viruses which are now used in blood banks worldwide.
