Mass Vaccination Triggers Viral Evolution Towards More Infectious Variants Says Top Virologist

Conducting¬†mass vaccination campaigns on a background of high infection rates generates optimal conditions for breeding even more infectious Sars-CoV-2 variants. The combination of massive, spike-directed immune pressure combined with high infectious pressure rapidly allows these variants to reproduce more effectively such as to outcompete previously circulating variants/ strains. Mass vaccination, therefore, promotes viral evolution towards …
