It was found that the new coronavirus infection (Corona 19) vaccine developed by AstraZeneca-Oxford University has only 10% preventive effect against mutations originating in South Africa. Previously, some countries, including South Africa and Switzerland, stopped vaccination against AstraZeneca.
According to the BBC on the 8th (local time), a small-scale clinical trial conducted by Oxford University and the University of South Africa’s Bitbadersland showed such results. Professor Xavir Maddi, who led the test, said on BBC Radio, “As a result of the test, the (AstraZeneca vaccine) preventive effect against mutations in South Africa is estimated to be 10%.” He pointed out that it would be difficult to come out in %. “Even in a relatively young age group, where there are few people with underlying diseases such as hypertension or diabetes, the AstraZeneca vaccine does not prevent mild and moderate infections (due to the South African mutation),” he added.
According to the New York Times (NYT), 19 out of 748 people who were vaccinated in a test at the University of Bittersland were infected with the South African mutation. “There is virtually no difference,” the newspaper explained, considering that of the 714 people who took placebo, 20 were infected with the mutation.
The trial was designed to determine whether the AstraZeneca vaccine has a prophylactic effect of more than 60% regardless of severity. The fact that the total number of participants was relatively small at 2,026, and the fact that the participants were composed only of young and healthy people with a median age of 31 is considered a limitation. Professor Mardi thought that the AstraZeneca vaccine would be effective in preventing severe illness. “The AstraZeneca vaccine uses a technology similar to that of the Johnson & Johnson (J&J) vaccine,” he said. “As the J&J vaccine works well in several age groups, which are the most severely risky, there is some hope for the AstraZeneca vaccine.” Said.
As the results of clinical trials that the AstraZeneca vaccine cannot prevent mild and moderate symptoms caused by mutations in South Africa became known, South Africa decided to temporarily withhold the vaccination the day before.
