I don't know but I've got bad news for you: we will never have a vaccine for this. https://twitter.com/pojanowski/status/1252630922752593920

Calculate the consequences of that as you will.

Polio is not a coronavirus, it's poliovirus. We have never been able to successfully vaccinate against any coronavirus, and we have tried several times. SARS, MERS, now COVID-19...0% success rate. https://twitter.com/Intrpdtravlr/status/1252633389468811266

i must say that i find it funny and strategically incompetent not to tack towards maximum pessimism here. i'm not talking off the top of my head. best-case scenario is, we make a massive research breakthu & in 2yrs develop the 1st human coronavirus vaccine. and...what 'til then?
