According to Bloomberg, the results are “part of tests of its vaccine against a lab-created virus that had all the mutations found in the South African variant, which is thought to spread faster than earlier versions”. “The mutant virus has become a stumbling block for vaccine campaigns, with South Africa halting the rollout of AstraZeneca Plc’s shot after a study showed it didn’t work as well in preventing mild illness involving the variant first identified there”. The AstraZeneca COVID-19 vaccine – of which South Africa has received one million doses – has proven ‘minimally...
AstraZeneca Vaccine Only ‘Minimally Effective’ Against South African COVID-19 Variant, says Researchers

So far, South Africa has received one million doses of the Oxford/AstraZeneca vaccine. In an official report, researchers from South Africa and the UK found that “viral neutralisation by sera induced by the ChAdOx1 nCoV-19 coronavirus vaccine against the B.1.351 coronavirus variant were substantially reduced when compared with the ‘original’ strain of the coronavirus”. /* custom css */ .tdi_3_ec0.td-a-rec-img{ text-align: left; }.tdi_3_ec0.td-a-rec-img img{ margin: 0 auto 0 0; } Professor of Vaccinology at the University of Oxford, Sarah Gilbert revealed that efforts are alrea...
