The tldr is basically:
* Guy vaccinated himself very, very often for reasons unknown.
* We observed interesting things [implied: that we probably would never have observed otherwise because nobody would ever set up a study for this specifically] like mildly elevated levels of spike-specific B cells
* It doesn't look like it made him any more or less protected.
* The guy never caught covid as best as anyone can tell, but other factors (was he a recluse?) can't be ruled out.
* We're not endorsing this as a strategy, we're just writing up interesting stuff since the opportunity arose.
The news media is also widely reporting this. https://www.google.com/search?q=217&tbm=nws
