The use of the AstraZeneca vaccine has been banned in South Africa. A vaccination campaign was scheduled to begin in this country from Monday with this vaccine, but the move was taken when the vaccine was found to be less effective against the South African variant of Corona.
This has caused new concerns to the world regarding the effect of vaccines against new types of the corona. The Serum Institute of India has provided one million doses of the AstraZeneca vaccine to South Africa. Many scientists in this country, along with South African Health Minister Zweli Mikhaize, have shared the results of several trials of Corona vaccines.
But there have been concerns about AstraZeneca. This vaccine has been found to be less effective against a variant called B.1.351. This variant was first identified in South Africa. Mkhize said the vaccination, which began on Monday, has been stopped until the Committee of Scientists decides to go ahead with the vaccine.
