Maybe(?) in Sweden, but not in the USA. It is not over until death counts are close to zero without a lockdown. The lockdown just postpones the epidemic until we have a vaccine or until we lift the lockdown at a later date. @MLevitt_NP2013https://twitter.com/MLevitt_NP2013/status/1287036738565738496 …
No, not 100%. At some point herd immunity will kick in, but we do not know at what % that happens. If we had a good vaccine, we could protect the elderly and other high risk groups, and also generate herd immunity faster.

Do you share the idea that it may take less% to get herd immunity due to the cross immunity of other Coronavirus thanks

We may also need annual vaccine if immunity doesn't last and/or because of mutations.
