South Africa Health Minister Says Govt AstraZeneca's CoronaVirus Vaccine May Sell supplements. Although, a clinical test found that the 501Y.V2 variant of the corona virus did not have much effect on a less severe disease. Subsequently, its use in the vaccination program was stopped. Based on data found in a study by Africa's Witwatersrand University and Oxford University, AstraZeneca stated that its vaccine was offering limited protection against this variant.

The company says that now this vaccine will be prepared for the new virus and it will be ready soon. The corona virus has been mutated thousands of times during this month of the epidemic, but scientists are worried about three variants that are more contagious than before. These comprise Britain's Kent, South Africa, and Brazil's variants. South African variants of these appear to be resistant to the vaccine and have been found in many parts of the world. While working on the vaccine for the new strain, Johnson & Johnson and Novavax have also stated that their vaccines are not effective against the new strain. Similarly, Moderna is preparing booster shots for the new variant, while the Pfizer-Biotech  vaccine has also been found to be less effective. 100 million doses of the Oxford vaccine have been bought by Britain and millions are being vaccinated. On the other side of the coin, 11 cases of variants in non-commuters pose a threat of community transmission due to which the testing is being sped up.
