Medical advances are cause for optimism, says doctor Jean-Pierre Thierry. But this excitement must be accompanied by public health reform, at the risk of creating more social tensions. And give its full place to prevention.
This article comes from the magazine Les Dossiers de Sciences et Avenir n°220 dated January/March 2025.
