Okay, I'm not quite sure how to respond to the concept. A lockdown is about distance, right? Distance is a key part of preventing and maintaining control of a respiratory illness transmitted by air. Distance is an important part of that; lockdown generates distance, so that's a fact, not an opinion.
It is a luxury if we don't support people who are homeless, under-housed and can't stay at home, and that is a key, core part of this. A lockdown requires a heck of a lot of support, and that should be provided and shouldn't be a luxury. Otherwise, vaccines are an adjunctive measure. You don't vaccinate your way entirely out of a lockdown situation or a high-spread situation. Everyone touts the U.K.; they used the lockdown with a massive vaccine rollout.
Then, to be clear, that's a combination measure. Vaccines are your long-term plan, not an acute plan. I'm happy to do an infectious disease management lesson on that, but that's the actual part of it. There's no such thing as one or the other.
