> The virus would need to completely diverge from SARS-CoV-2 in order to fully defeat

Yeah, you shouldnt be making these claims if you don't have specific background or understanding of what you are talking about

All current vaccines target few/couple specific proteins and protein groups on the virus spikes which interact with our cells, if these couple spikes/protein groups change then the vaccines stop being effective, you don't need a complete divergence of the vaccines to stop working as the vaccines don't target the "whole virus" to begin with, just specific parts of it, that was the worry with Delta and is the worry with this new strain
