PARIS:- Vaccinations, antibiotics and antivirals are medical breakthroughs that have saved millions of lives in the 20th century, even if today they are increasingly contested or taken for granted. The success of modern medicine presents a paradox: as disease and epidemics are progressively brought under control, the public sees less need for medical treatment. “We are in a regressive dynamic of defiance vis-a-vis medicine that worries me and is fuelling the desire for alternative medicines,” says recognised French doctor, researcher and microbiology professor, Philippe Sansonetti.
