COVID-19 mutant: E484K maybe make vaccine ineffective

COVID-19 mutant: E484K maybe make vaccine ineffective. COVID-19 mutant virus is now “escape mutant”, scientists: fear of making the vaccine ineffective.

Recently, scientists have found an “escape mutant” virus on the mutated new coronavirus discovered in South Africa and suspected that it may invalidate existing vaccines. Currently, this mutant virus has spread to 12 countries.

According to a report by CNN on the 13th, this “escape mutant” virus is named “E484K” and it has been proven to escape certain antibodies produced by the vaccine.

According to the report, according to the current situation, scientists suspect that the virus containing the “E484K” mutation or the combination with other mutations will invalidate the vaccine. In addition, scientists are also worried that viruses containing the “E484K” mutation may be a manifestation of the ability of the new coronavirus to mutate. If this mutation occurs within a few months, other problematic mutations may follow.

In addition, according to the BBC’s previous report, Professor Suraçois Baroque of University College London said, “The E484K mutation has been found to reduce the antibody recognition rate. Therefore, it helps the SARS-CoV-2 virus bypass previous infections or The immune protection provided by vaccination.”

According to CNN, the virus containing the “E484K” mutation is not only present in the variant virus “501.V2” found in South Africa. According to the Global Influenza Data Initiative (GISAID), the virus containing the “E484K” mutation has spread to the UK , France, Australia, Germany, Japan, South Korea, Holland, Switzerland and other 12 countries.
