"There is a huge logistical exercise in vaccinating large numbers of people - the UK has bought enough for 20 million people. And don't forget, unlike the flu vaccine, this one requires two doses.
Health and care workers along with older age groups will be prioritised. But given it takes a month from the first dose for an individual to get the full protection and the fact there are 12 million over 65s - nine in 10 deaths have been in this age group - winter is likely to be well gone by the time significant numbers are protected.
England's deputy chief medical officer Prof Jonathan Van-Tam was unequivocal this week when he said he didn't see the vaccine "making any difference" this winter.
And the problem is that once lockdown is lifted in England, cases are likely to take off again. It is, after all, winter, when respiratory viruses tend to thrive.
Does that mean another lockdown in a few months? This is the nagging fear.
Ministers are just "deferring the problem", says Prof Mark Woolhouse, an expert in infectious diseases at Edinburgh University, who sits on the government's committee on modelling.
Even with the vaccine the virus is "not going away", says Sir Jeremy Farrar, a member of the government's Sage advisory group.
It is, he says, now part of humanity and here to stay. Instead, the most we can hope for is providing some protection to those who are most at risk.
The sad reality is that, despite the vaccine breakthrough, we are still going to have to learn to live with Covid this winter - and beyond."
