Vaccine programmes have sprung up around the world since late 2020, as governments look to inoculate enough people for a return to "normal". Many of these programmes remain in the early stages as they focus on inoculating society's most vulnerable, many of whom have spent months cooped up inside. Protecting them remains paramount, given their susceptibility to the virus, and officials in the UK hope to cover the cohort by next month.
The UK reentered national restrictions earlier this month, as the Government sought to curtail surging Covid cases.
A tidal wave of infections threatened to overwhelm the NHS, and since the new lockdown materialised, officials have focussed on expanding the vaccine programme.
They now have three vaccines at their disposal, and each newly inoculated person is a step closer to the normality many people crave.

But immunity to the virus doesn't spread to lockdown rules, which everyone must observe until they are no longer necessary.
Only over-70s can currently get the jab, and once they receive it, it will take some time to affect the overall case rate.
Scientists designed the vaccines to blunt the blow of a Covid infection, and primarily protect from the most severe effects.
They can't guarantee people will never get infected or pass it on to others, meaning there is still an overall risk of transmission.
