Virus discoveries in global spotlight
The sharing of this year's Nobel Prize in Physiology or Medicine by three European scientists for their discoveries of two serious viruses has attracted considerable criticism in the scientific community.
The choice of the two French prize winners, Françoise Barré-Sinoussi and Luc Montagnier, has left people wondering whether their American co-discover Robert Gallo should also have received the honour. The Nobel
Assembly has justified their choice by saying that they only award the prize for the actual discovery.
The prize is also shared by Germany's Harald zur Hausen for
his discovery of HPV, which has led to the development of a vaccine for cervical cancer. He has received half the prize, the other two a quarter each.
