I think the hope is that we could be closer to herd immunity than we think.

  Any herd immunity scenario is conditionnal on immunity is long-lasting, which is far from certain considering related viruses are recurring seasonally or in single-digit year intervals. Don't bet the farm on it.

    Even if infection doesn't confer permanent total immunity, subsequent reinfections are likely to be less severe as the immune system is primed to respond. So herd immunity is still a viable strategy.

    Maybe, but this particular virus is believed to not mutate much.
