I mentioned the Telegraph earlier.
This lady is a Telegraph columnist, and one of the many strident voices against mainstream science on COVID.
Today, she displays her total ignorance of COVID specifically and genetics and immunology generally.
For a football analogy, this is the equivalent of claiming that as swapping me for KDB is just one player different, City would be just as likely to win the Champs league with me in the side.
(She's also wrong about it being only one mutation from the original "wild type" virus)
