So far, a total of 137,897 people in the UK have been vaccinated, according to Nadhim Zahawi, who is overseeing the coronavirus vaccine rollout.
On Wednesday, Zahawi tweeted that the vaccine program had gotten off to a "really good start" and gave a breakdown of the numbers.
Here's those numbers.
Northern Ireland: 4,000.
Zahawi added that the number of vaccinated people would continue to rise as distribution in primary care networks takes effect.
But its possible that only around half of the population in England will be able to get vaccinated next year, according to a new report from the National Audit Office.
The report estimates that only 25 million people -- less than half of England's population of around 56 million -- could be vaccinated in 2021. That's if, and when, sufficient vaccines are available.
The UK government has signed five contracts for potential Covid-19 vaccines, including Pfizer/BioNTech's offering, which is currently being deployed.
The contracts will provide access to 267 million potential doses at an expected cost of £2.9 billion (US $3.9bn), according to a report released Wednesday by the National Audit Office.
- 100 million doses from Astra Zeneca/Oxford
- 60 million doses from Valneva
- 40 million doses from Pfizer/BioNTech
- 60 million doses from Novavax
- 7 million doses from Moderna
The report also said an estimated 46,000 staff may be needed to support the deployment of the vaccines, noting the challenge of current staff shortages.
