I have a mate who works as an immunologist and whose dept is involved in the development of the vaccine. I work in a gov dept (on a fixed term contract so no pension and no fat cat salary!) and have lots of friends and ex-colleagues who work in government, the City and local politics.
All that said, here's my view...
I think without Brexit, we'd have come out of this by next Xmas. Everyone who needs to be vaccinated will be by then. Without Brexit, the economy would have started to recover; we might even have been able to put some positive changes in place as a result of the pandemic (e.g. more working from home, closer ties within neighbourhoods, more funding for mental health care).
With a no-deal Brexit looming, we are absolutely fucked. Next year is going to be very very hard - and I say that as someone with a white collar job, money in the bank and lots of support. There will be food shortages; there will be riots; more of the NHS will be privatised so services will be cut; unemployment will soar. I'm in my late 40s and remember the miners' strikes - I think unemployment and poverty in many areas will be comparable to that.
Johnson will be gone by March, leaving someone else (probably Sunak) to clear up the mess. I wouldn't vote Tory if you paid me, but at least then we'll have someone with a brain in charge. However, he'll be looking to make money by any means possible. That means giving contracts for government work to the highest bidder, regardless of quality. It means raising taxes. It means benefits will be cut AGAIN.
I think the worst will be over by 2022, but the recession will go on for 2-3 years beyond that.
I'm sorry to be the voice of doom, but if you're making decisions about buying or selling houses, or which job to take, or whether you can afford to put your kid through private school - go for the safest option you can. We're all going to need to get our heads down and endure for a while.
