I'm likely to be mid-December as I'm in no. 7
I think timelines are against anything but a tiny number of vaccinations this year.
Pfizer will not file the data from this trial with regulatory agencies until the safety readout, which they've said will be late November (today's news is on efficacy). Then the relevant agency needs to review and approve. That normally takes 12-18 months(!) but in current circumstances they're talking about short numbers of weeks. Pfizer will most likely prioritise a US submission; EU will probably follow very shortly.
Allow time for distribution, logistics and prioritising, and it seems very unlikely more than a handful of vaccinations this year.
As we're leaving the EU on 1st Jan, it's possible approval could be delayed by that, if not approved before then.
