England gave out 344,464 Covid vaccines on Thursday, official figures show, as Britain reaches the halfway point of its target to immunise 15 million of the most vulnerable by mid-February with first doses now given to 7.5million.
The NHS data shows that 344,464 vaccinations were administered across England on January 28 – of which 343,193 were given to people receiving their first dose.
The UK needs to be vaccinating at least 400,000 people every day over the next two weeks in order to fulfil Number 10‘s promise of immunising all 15million of the most vulnerable Brits by February 15.
Figures show that 1,271 had received their second jab on Thursday and the number of first vaccinations in England were up by 36 per cent, 91,472, from 252,992 immunisations on Wednesday.
However, a vaccine postcode lottery means that while 84 per cent of over-80s have been immunised in the North East and Yorkshire, this is lower at 78 per cent in the South East and only 65 per cent in London.
It emerged earlier this week that vaccine supplies are being diverted away from the North, which is storming ahead with its vaccine drive, and redirected to the South to help it catch up.

HOW DOES THE J&J VACCINE WORK?
Johnson and Johnson’s vaccine is made from a weakened version of a common cold virus (adenovirus).
The team have modified the adenovirus so it can enter cells but can’t replicate inside them or cause illness.
Researchers have already used this technology to produce vaccines against a number of pathogens including flu, Zika and Middle East respiratory syndrome (Mers).
After the J&J vaccine is injected into a person’s arm, the adenoviruses enter human cells and travel to their nuclei, the chamber where the cell’s DNA is stored.
The vaccine are programmed to carry the genetic code of the coronavirus’s ‘spike protein’, which Sars-CoV-2 uses to invade the body.
Iit uses this genetic code to trick the body into mounting an immune response, priming the immune system to attack coronavirus if the real virus infects the body.
Meanwhile it was revealed today that Johnson and Johnson’s coronavirus vaccine is 66 per cent effective against the disease, early trial results reveal.
The jab is made by Janssen – the Belgian arm of the US pharmaceutical giant – uses similar technology to the Oxford vaccine, making it easy to transport and store, but requires just a single injection to protect against Covid.
The scientists also said no safety concerns were raised in the trial involving 44,000 volunteers – a third of which were over 65 and two fifths suffered from an underlying health condition such as obesity, diabetes and HIV.
The UK has ordered 30million doses, with the option of purchasing 22million more, and experts say it could be rolled out in Britain by late February.
It comes after Novavax announced its jab was 89 per cent effective last night. Both will need to be reviewed by Britain’s medical regulator before they can be deployed.
The figures revealed today show a lower efficacy compared to others reported so far, with Pfizer and Moderna’s both around 95 per cent.
But scientists said this is still a very good result, with the World Health Organization initially setting the threshold for effectiveness at around 50 per cent.
The new vaccines could significantly speed up the programme which has been held back by supply shortages.
Pfizer’s and AstraZeneca’s are the only ones currently being rolled out in the UK and have accounted for the 7million doses given out already.
Another jab, made by US firm Moderna and approved by the British regular, won’t be delivered until March because the UK was late to get its order in.
Janssen said it recorded 468 infections in its phase 3 tests. They added it was shown to have slightly less efficacy (57 per cent) in trials in South Africa, where a mutant strain of Covid-19 is feared to make jabs less potent.
The Health Secretary Matt Hancock heralded the results as ‘good news’ and said the UK’s approach of securing large vaccine stocks was ‘paying off’.
‘After the good news last night of the effectiveness of the Novavax vaccine that, should it be approved, will be made in Teesside, this lunchtime we just had more good news about the new Janssen vaccine,’ he said.
So far the UK has placed orders for 367million doses of the seven most promising Covid vaccines — made by AstraZeneca , Pfizer , Moderna, Valneva, Janssen, GlaxoSmithKline and Novavax — at a cost of £2.9billion
The single-dose vaccine invented by Johnson & Johnson was shown to be 66 per cent effective in trials, but 86 per cent effective at preventing severe Covid with no participants requiring hospitalisation due to the disease
Vaccines WILL limit the spread of coronavirus – but we won’t know how by much until mid-February, experts say
Britain’s vaccine roll out will limit the spread of coronavirus, but by exactly how much will not be made clear until mid-February, experts say.
Providing a boost to the UK’s hopes of ending lockdown, England’s deputy chief medical officer Jonathan Van-Tam said jabs ‘couldn’t fail to have some effect on transmission’.
He said it was less a question of ‘will they?’ and rather ‘to what extent’ will inoculation help to reduce the spread.
But Boris Johnson and his chief scientists tonight said experts won’t know much effect the coronavirus vaccines are having on the country’s epidemic until mid-February,
The PM said the impact of the jabs won’t be felt in hospital and deaths data until then due to the lag in time it takes between getting injected and developing immunity.
He told a Downing Street press conference tonight that he would not consider lifting lockdown restrictions until he’d seen concrete ‘evidence that those graphs are coming down’.
The immunisation drive has only really got up to speed in the last few weeks and it takes between a fortnight and a month for a person to build up immunity.
Both the Pfizer and Oxford University vaccines have been proven to block severe illness, so experts hope they’ll start to make a dent in the death and hospitalisation rates in the coming weeks.
No10’s scientists will be monitoring those metrics, specifically in the most vulnerable groups – including the over-80s, over-75s and care homes residents – who are currently receiving the jabs.
So far 6.8million, or one in 10, people in Britain have received at least one dose of the vaccines.
In three weeks time, when most of those people have protection, experts will expect to see a near 10 per cent drop in hospital admissions.
Not all of the people vaccinated will be immune, however, because the jabs are not perfect. Pfizer’s is 95 per cent effective at blocking severe disease, while Oxford’s is around 70 per cent.
‘This is a single dose vaccine, and our approach of buying abroad and making here at home is paying off.’
He added: ‘I want to say a huge thank you to everybody involved who’s helped get the UK in this pole position to protect our population and to make sure we get out of this pandemic.’
In the trials, researchers tracked illnesses starting 28 days after vaccination which scientists say is about the time when immunity would be triggered if participants had received a two-dose vaccination instead.
The shot uses a cold virus to carry the Covid-19 spike protein – which it uses to invade cells and the part of the virus that is attacked by antibodies – to trigger an immune response.
This is similar to the Oxford/AstraZeneca jab, which also uses an adenovirus with spike proteins from Covid-19 attached.
Both doses can be stored in a household fridge, a significant leg up over Pfizer’s which must be stored at -75C (-94F) before use.
The Oxford/AstraZeneca jab was also shown to be 62 per cent effective during trials, which health chiefs said was an excellent result considering they were not sure whether the jab would work until they had the results.
It comes as England’s coronavirus R rate is now between 0.7 and 1.0, according to SAGE’s latest estimates — but official figures show more than a million people were carrying the virus last week as infections levelled off.
The Government’s Scientific Advisory Group for Emergencies said the reproduction value – the average number of people each Covid patient infects – had fallen only slightly from last week’s range of 0.8 to 1.0.
The group warned that cases ‘continue to be dangerously high and the public must remain vigilant to keep this virus under control, to protect the NHS and save lives’. For the UK as a whole, SAGE estimates the R rate is between 0.7 and 1.1, a change from 0.8 and 1.0 last week.
The widening of the range ‘reflects a change in uncertainty’ in how quickly the virus is spreading, the experts said.
SAGE cautioned that its R rate estimate is about a week out of date and only looks at infections, hospitalisations and deaths up to January 25. Experts would have hoped that, three weeks into the national lockdown, the R rate would come down more significantly.
There are fears the super-infectious Kent variant, which is thought to be at least 50 per cent more transmissible than the original strain and 30 per cent more deadly, has made lockdowns less effective.
Meanwhile, an Office for National Statistics report published today estimated that 1.01million people were carrying the disease at any given time in the week ending January 23, the equivalent of one in 55. But there were still large regional disparities, with one in 35 thought to have had the virus in London compared to one in 85 in Yorkshire and one in 70 in the East Midlands.
It is the fourth week in a row the ONS believes more than a million people in England were infected with Covid on any given day and today’s figure is down only slightly on last week’s estimate of 1.02million. The ONS estimates around one in 70 people were carrying the virus in Wales last week, one in 50 in Northern Ireland and one in 110 in Scotland. Statisticians said cases had ‘levelled off’ in all three nations.
Separate data from from ZOE COVID Symptom Study found daily new cases are falling in all regions of the UK, ‘but the pace of decline has slowed down’.
