Bold of you to think there will be any such thing as lasting herd immunity via natural infection, when no other human coronavirus induces such immunity.

There are corona viruses spreading among humans all the time, a significant fraction of "common colds" are corona. Most doesn't get sick since we already have herd immunity against them.

if there is so such thing as immunity then waiting for the vaccine is pointless no? ...so what is the lockdown for again?

  > if there is so such thing as immunity then waiting for the vaccine is pointless no? The keyword there is lasting, we know immunity exists we just don't know for how long. If a vaccine could be distributed to enough people in a short enough time frame (we're talking billions and months) it could still wipe out the virus. But if that can't be done then mandatory vaccines for travelers could work. > ...so what is the lockdown for again? To keep the number of infections manageable and/or eradicate it entirely, it was never about stalling time for a vaccine.

    to keep the numbers manageable? all the hospitals are empty, the field hospitals they built for this have had 80 total patients out of the expected 10 million+ the whole purpose of "flattening the curve" was so that everyone one would get the virus but at different times, if no-one is getting it now, then that just means everyone will get it later
