Oh, that’s an interesting circumstantial evidence that I’ve not thought of. Do you by any chance have seen any evidence supporting this? If yes, I’d appreciate it if you could link it to me. For example, maybe a cell or animal study showing that vaccine-derived antibodies or vaccinated mice promote the evolution of SARS-CoV-2 variants. Without data like these, I’m not sure what to think about this hypothesis/circumstantial evidence.
