An article by the German virologist Christian Drosten was circulated a few days ago. His take is that virtually everyone who isn't vaccinated will get it. There is always going to be a large enough core of unvaccinated (and possibly unvaccinatable) people to keep the virus in circulation.

The "core model" was developed as a description of gonorrhoea - the ultra-promiscuous keep it going by playing pass-the-parcel with germs and every so often a bystander gets pulled in. Surprising to see it turn up again with anti-vaxxers playing the role of hookers.
