Studies by South African scientists of the AstraZeneca-Oxford vaccine against COVID-19 showed minimal efficacy in preventing mild and moderate cases of the new variant, which added to the mounting evidence that the B.1.351 variant makes current vaccines less effective. Is that truly the case, or are the milder cases actually patients who would have had very severe illness without having taken the vaccine, because the new mutant is being artificially introduced at much higher concentrations and is not really more infectious or lethal?
