Its not been confirmed, and I'm sure it won't be until its passed every stage and been approved, but it has been noticeable how over the last couple of weeks multiple experts have changed from expressing caution and saying it could be months before we get a vaccine to talking about starting a roll out in December or January. For them all to have changed at the same time makes me think they know something.
Then a few days later you had this from Fauci:
US expert Dr Anthony Fauci says it should be known by early December if vaccine is safe to roll out

And a leaked memo from the Eliot telling staff to be prepared for immunisation in December:
Hospital's managing director confirmed staff we on standby for a vaccine
