Wuhan Virus Strain Resists New Vaccine


The scientists have discovered several mutations of the SARS-CoV-2 virus, that trigger Wuhan virus diseases, which are resistant to certain types of antibodies.



The virologists at the Fred Hutchinson Cancer Research Center have found several mutations of the SARS-CoV-2 virus that are resistant to certain types of antibodies.

According to a report published in the scientific journal Nature, such mutations are masked, in particular, from antibodies produced by the vaccine of the American pharmaceutical company Eli Lilly from Indianapolis, and the "Regeneron" cocktail, with which Walter Reed Centre doctors treated US President Donald Trump.

The mutations affect a protein segment called the receptor-binding domain, which the virus uses to bind to and enter cells, the scientists stated.

The paper notes that the reason for this resistance of the coronavirus, most likely, should be sought in the mechanism of its interaction with the RBD protein segment (receptor-binding domain), which SARS-CoV-2 uses to enter cells.

At the same time, as the newspaper writes, some of these mutations are widespread in infected people in Europe, and a mutation invulnerable to all antibodies has been identified in the Netherlands and Denmark.
