What New Variants, AstraZeneca Vaccine Mean For Africa

SARS-CoV-2, the virus that causes Covid-19, has mutated, and there are several variants - one of which, B.1.351, was first detected in South Africa at the beginning of October 2020 and it now accounts for the vast majority of genetically sequenced samples in the country. Variants of Covid-19 mean that existing vaccines like the AstraZeneca/Oxford are less effective. Now Nigeria has detected several cases of the variant first spread in the UK - B.1.1.7 - as countries around the world impose more restrictions on travel from places with documented cases of the new variants.
