Todays' NYT has an article about malaria vaccine trails in Africa which is showing some promise. In there there is a quote:
No decision has been made about the price to be offered to poor countries and international health agencies. But “if a child will benefit, price will not stand in the way,” said Dr. Christian Loucq, director of the vaccine initiative.
Obviously, if that was the case the price would be set so that Glaxo would make zero profit from the vaccine and that is unlikely to happen. This is an variation of the argument that if just one life can be saved by during something it is worth essentially unlimited resources, which is clearly false. This is why the Copenhagen Consensus was introduced.
