Oh I think I see your perspective now. Yes, if you don't believe a vaccine will be developed then I can see where you're skeptical of the end game of testing and tracing. But your certainty of the unlikelihood of a vaccine is far too strong far too early. There are on the order of ten to a hundred promising efforts toward developing a vaccine well under way. It may very well be that a year or two from now, each of those will have failed. If that is the case I will be open to hearing about how best to manage this indefinitely, and you may be right that testing and tracing won't help that much (but it still seems like we may want to control the order and rate at which people are exposed). But we're really far from having the evidence to support your claim with any certainty. We haven't run out of ideas for how to make a vaccine yet, we're just getting started.
