Pfizer, in less than a month, “Vaccine effect on South African mutation is unclear”
Modena publishes similar findings in the same medical journal
South Africa starts vaccinating Johnson & Johnson instead of AstraZeneca
[앵커]
Studies have shown that the Pfizer’s COVID-19 vaccine has an unclear preventive effect against mutant viruses originating in South Africa.
Last month, Pfizer said that the South African mutation had little effect on it, but in less than a month, that changed.
As Modena produced similar results, all three major pharmaceutical vaccines following AstraZeneca became unclear in effectiveness against mutations in South Africa.

At the end of last month, Pfizer said its vaccine had little effect on the South African mutant virus.
They looked at the titers of vaccinators against the virus made from the South African mutation and said the reduction was less than doubled.

But in less than a month, the findings of this study were upset.
Pfizer, in a joint experiment with the University of Texas Medical School, found that infection with a modified virus, such as the South African variant, reduced the level of protection of the antibody by two-thirds.
However, because there is no standard for how many antibodies are needed to neutralize the virus, it is argued that it is difficult to say that a reduction in antibodies by a third than before is not effective.
The results of the new study were published in the New England Journal of Medicine, which published similar findings in Modena in the same journal.
Just last month, it was a position that the company’s vaccine would be effective against mutations in South Africa, but on the 17th local time, the actual efficacy of the vaccine was not yet revealed, and a study resulted in a paper and stepped back.
Earlier, the AstraZeneca vaccine also showed only 10% prevention effect against the South African mutant virus, so South Africa introduced the Johnson & Johnson vaccine instead of AstraZeneca.

As all of the world’s top three pharmaceutical vaccines have been shown to be ineffective or unclear in South African mutations, concerns about the variant virus are increasing.
