Paul Ewald Posted over 3 years ago Will medical advances against cancer mainly help people in wealthy countries or can they help all of the world's people? This contrast is important. Companies are very motivated to generate therapies that generate profits of many thousands of dollars per person treated. There isn't as much profit in creating a vaccine that will generate only a few dollars per person treated. We therefore cannot expect that these companies will be leading the charge to develop these more effective interventions. But we can insist that entities that are supposed to be looking out for the health of the entire population, such as the National Institutes of Health and the World Health Organization, work on generating the most effective interventions. They just may have to do it without enthusiastic support from the pharmaceutical industry.
