More than half of the government's target of 15 million people have now been given their first shot of a coronavirus vaccine.
The UK government has set a target of vaccinating the top four priority groups against COVID-19 by mid-February.
Hitting the vaccination target
In the last week, 358,297 vaccinations were carried out on average each day. The vaccination rate has been increasing as the government has expanded capacity by 76% every week on average over the past four weeks.
To reach the target, the government would ideally be achieving an average of 394,934 per day in the remaining 18 days.
But the daily figure fluctuates. Recent shortages in supply and the snow which closed some centres at the weekend both caused a slowdown in the last few days. Similarly, a spurt in vaccinations could reduce the daily rate required.
Progress among priority groups
The mid-February target involves offering a first dose to all people in four priority groups starting with residents in care homes and their carers as well as those aged 80 and above.
New data published by NHS England suggests around 80% of them have now received their first dose by 24 January.
But, the picture varies widely depending on where you live.
The data is broken down into areas known as Sustainability and Transformation Partnerships (STPs). These are collaborations between local authorities and healthcare providers.
Gloucestershire STP has vaccinated 91.1% of its over 80s while South East London and East London STPs have vaccinated a little over 60%.
The table below shows the areas with the highest and lowest proportion of over 80s given a jab for coronavirus.
Ethnic minorities less likely to be vaccinated
There are variations in vaccination rates among ethnic groups in England too. NHS England data also reveals 9.7% of the White population was given the first dose. For ethnic minorities it was 5.7%.
The figures however don't take into account variations in the number of elderly people among different ethnicities.
Concerns around vaccine hesitancy were raised by the government's scientific advisers in an undated document released earlier this month.
Seeming to concern those worries, less than half of Black adults have said they are likely to have a jab, the lowest among groups surveyed by the Office for National Statistics.
Oxford University researchers have also estimated lower vaccination rates among ethnic minorities.
The team from 'OpenSAFELY' analysed 961,580 people who took the vaccine within the first five weeks and found that 42.5% of elderly white people had their first dose compared to 20.5% of black people aged 80 years and older.
The study also looked at vaccination rates in deprived areas of the country and found that 37.9% of those over 80s in the most deprived area had received a jab compared to 44.7% in the least deprived areas.
So while 7,891,184 people have received their first dose and the government is confident of meeting its target there are early warning signs in the data about whether some communities will be covered more than others.
