To be fair, you are stigmatizing someone for offering a correct observation (that the successive COVID variants have proven less debilitating and deadly) and for asking a question that must be on many people’s minds: can monoclonal antibody administration promote resistance analogous to bacterial antibiotic resistance?
Be aware that live virus vaccines are certainly not monoclonal antibody injections.
As well, rather than spending your mental energy developing excuses to dismiss, why not think on the subject at hand? You should wonder why this mouse model produces broadly neutralizing antibodies in response to COVID spike proteins while the human immune system does not.
That’s a bit interesting to the subject of COVID, isn’t it? Certainly more so than windmills and politics.
