1. Mask better 2. Distance better 3. Hope no big problem with vaccine production, adverse effects, or variant vaccine escape: by March deaths should decline, by June cases should decline substantially and by September we’ll be close to the new normal in the US.
BUT (see next).

As cases decline, if we don’t stop spread, as natural immunity+vaccine immunity increases from ~30% to >50%, selective pressure on virus to evade immunity increases. More uncontrolled spread, more likely there will be variants which escape either or both types of immunity.

That another reason why testing, isolation, contact tracing, and quarantine will remain extremely important for at least another year.
