The OP, of course, is garbage science. But then, it came from the WSJ opinion page, and that's crank heaven.
Viruses do not have intelligence. They do not "try" to get around vaccines.
Viruses just mutate randomly in every direction. The more viruses, the more mutations. That is, the more COVID cases, the more mutations.
The best way to stop mutations is to reduce cases of COVID. That's why the variants don't arise in nations with high vaccination rates.
The bivalent vaccine does provide some protection against new variants. Having previously had COVID provides almost none.
