> Covid spreads far more easily indoors. Breakthrough cases are becoming more common. Group immunity through boosters (or exposure) is more effective at preventing the spread of covid and reduces the chance that any one individual will catch COVID (and continue to spread it). I'm not aware of any data saying that group immunity through boosters has significantly stronger effect than boosting itself or than group immunity through the original vaccination. Care to share that? My priors are that group immunity among boosted individuals would be very mildly better, but I'm not aware that that study has been done. When we evaluate policy decisions, we should base those decisions on quantifiable tradeoffs, not simply on whether there is benefit to a policy. At some point, the diminishing returns of marginally increased safety are not worth the societal costs. To me, given the current data, it seems we're at that point for vaccination. As to the other comment thread, I'm happy to address any questions you have there, in order not to repeat the discussion here.
