Scientifically speaking, how does the current vaccination strategy differ from a deliberate attempt to breed an ADE inducing strain in the wider population? It seems like stubbornly vaccinating everyone with the same old spike protein, which is also the one accumulating the most mutations (because of the vaccine or not) would be the fastest and most efficient way to do exactly that, apart from doing it at an accelerated pace in a lab with the usual GoF methods. What other major difference is there apart from it happening in humans directly instead of a beaker?
How would a "dead" vaccine containing the same outdated spike protein make any difference here compared to some mRNA/vector vaccine that builds the spike protein in vivo?
