Preliminary studies show that Pfizer vaccine is effective against the mutation of the novel coronavirus strain N501Y.

According to the Associated Press on the 8th, preliminary research shows that the Pfizer vaccine is effective against a common mutation N501Y of the novel coronavirus mutant strain found in the United Kingdom and South Africa.

Protein mutations in N501Y have previously been shown to increase the binding of proteins to the ACE2 receptor, which is the entry point to human cells.

This means that the ability of viruses to enter human cells can be enhanced.
