Geert Vanden Bossche is back, and this time he’s blaming COVID-19 vaccines for driving the evolution of more dangerous “escape variants” of SARS-CoV-2, the coronavirus that causes the disease, that are capable of evading vaccine-induced immunity. As antivaxxers making this argument always do, unfortunately, he ignores the much larger problem in which free circulation of the virus is a far more powerful driver of evolution than the relatively small proportion of the world population that has as yet been vaccinated.
