There is enormous bullishness inside Whitehall at the progress of the vaccine rollout. Today the government claimed victory over its first deadline - the rollout of the first jab to residents of care homes.
The next big deadline is 15 February, when all 15 million in the most vulnerable four categories should be completed.
There is a hope inside government that this might even be done early.
Even though some supply is uneven, there are thought to be massive stocks in warehouses which will carry them past this moment regardless of any interruptions.
Where then? Ministers know the political and economic dividends of continuing with a fast and efficient rollout are huge and hope politically it will erase some of the bad memories of 2020.
There seems little serious challenge with supply, even though sometimes it is lumpy. Issues with the EU have been dealt with for now.
Matt Hancock, health secretary, said that the UK has 400 million doses on order, clearly more than enough.
The only part of the UK where the rollout seems slower is Scotland.
On Sunday, just 9,628 patients received their first vaccine dose - the fewest since the Scottish government began publishing figures on 11 January - taking the total to 575,987.
First Minister Nicola Sturgeon put the speed down to the day of the week. Otherwise, she maintains Scotland is "ahead of schedule".
Where could this all get the government? There are some in Whitehall who say there is now the realistic prospect that every adult might have been offered the first jab by the start of May.
This is faster than any target mentioned publicly by ministers, and though possible would require the rollout to speed up yet faster.
It would be quite the achievement, both for Kate Bingham and the vaccine taskforce, and the NHS which has led the rollout.
This would also, conveniently enough for Boris Johnson, be just in time for the elections on 6 May, the date will determine composition of future administrations in Scotland and Wales, as well as mayoralties and council control across England.
The speed of the vaccine rollout does pose challenges of a different sort for government.
Three weeks after the first jab, people will have a substantial level of protection. The infection rate is likely to drop swiftly, as will the rate of hospitalisations in March.
At this point, how will the government hold back people who have spent most of the last year indoors and enforce social distancing?
Ministers will need to act fast at this point to stay ahead of public opinion and not allow a free for all.
All things considered, however, it will feel like a good problem to have in comparison to the challenges of much of the last year.
