Sadly, the ZeroCovid ship has sailed. Vaccines do not prevent infection or transmission (1). All vaccines appear to do is to (hopefully) dull the severity of the infection once you've got it. Plus now we have animal reservoirs, and no way to vaccinate those.
Edit: (1) Obviously we should talk about the degree of infection and transmission reduced by vaccines, and not in black/white terms. I haven't seen conclusive data, just the Israel Delta charts that are not particularly encouraging.
