Moderna Pharmaceutical, Moderna vaccine is effective against the mutant virus

American pharmaceutical company Moderna has announced that the vaccine has also been effective against the mutated new coronavirus found in the United Kingdom and South Africa. However, regarding the mutant virus found in South Africa, the value of the antibody that suppresses the action of the virus has been reduced to one-sixth, so additional trials to enhance the effect and clinical trials of new vaccines will be started.

Announced that it was obtained.

However, for the British mutant virus, there was no noticeable change in the antibody level that suppresses the action of the virus produced by the vaccine, while for the South African mutant virus, the antibody level was about 6 minutes. It means that it has decreased to 1.

Moderna says that both antibody levels are above the required levels and are effective, but for South African mutant viruses, tests will be conducted to see if additional vaccinations will increase their effectiveness, and they will respond to the virus. It is also planning to start clinical trials of new vaccines that can be made.
