On topic, I saw this paper and thought it an interesting read.
However, there's a few things at issue.
There's more than one way to activate B cells, one of which doesn't require receptor crosslinking. In fact, most B cell responses against viruses aren't via simple receptor cross linking because it does require a highly repetitive antigen (target).
Second, there's a common mistake in the media to call antibodies "immunity," when they're only a single aspect of immunity. Antibodies wane naturally after the infection is cleared. They have to. But that's why memory responses are important.
Finally, we're still in a time frame where new strains have novel enough changes that it can get around antibodies but not necessarily T cells. It's the T cell responses that are likely responsible for continued far lower numbers of hospitalizations and deaths that we see with newer strains.
You mean income. If insurance companies are covering it, the x-rays are a revenue stream.

But what's the angle on that?
I figured it was preventative and, therefore, a cost saving measure.
