Boris Johnson and the deputy chief medical officer Jonathan Van Tam this evening revealed their intense emotions after being told a coronavirus vaccine developed by Pfizer can now be rolled out across the UK. 

Mr Johnson described it as a ‘huge moment’ and also ‘a very moving thing’ while Mr Van Tam admitted he was ‘quite emotional’ after he got the news that the Medicines and Healthcare Products Regulatory Agency (MHRA) had given the jab the green light. 

However, speaking on the day that his new Covid-19 tier system was implemented across England, Mr Johnson warned the ‘worst thing now would be to think that this is the moment when we can relax our guard’. 

The Prime Minister said it would be wrong to think it is ‘game over in the fight against Covid’ and ‘this is not the end’ as he urged people to stick to the new rules ahead of a potential return to normal life in the Spring.    

The Joint Committee on Vaccination and Immunisation (JCVI) today published its priority list for which groups will receive the jab first, with elderly care home residents in the top category.  

But there are growing fears care home residents could be made to wait for the vaccine because of the logistical challenges of moving around medicine which must be stored long term at -70C. 

Sir Simon Stevens, chief executive of NHS England, said as he stood alongside Mr Johnson and Mr Van Tam at a Downing Street press conference that the vaccine rollout will begin next week at 50 ‘hospital hubs’ in England.  

Mr Johnson then admitted that while the Government wants to get the vaccine into care homes ‘as fast as we possibly can’ there are ‘difficulties’ associated with that process.    

Lorries loaded with the first batches of Pfizer/BioNTech’s coronavirus vaccine are already on their way to Britain after the breakthrough jab sealed approval from the UK’s medical regulator.  

Thousands of doses of the vaccine were shipped from Pfizer’s factories in Belgium this morning within hours of it being given the green light by the MHRA, making Britain the first country in the world to have a clinically authorised Covid-19 jab. The doses could reach Britain as soon as tomorrow. 

Speaking in Number 10 this evening, Mr Johnson said: ‘This is a huge moment and… it is also a very moving thing.

‘I am really lost in admiration for science and the ability of scientists to solve human problems in the way that they can.

‘This is not easy. Bear in mind we have got a vaccine now for Covid that really, really works, there is no question that it works, but we haven’t got a vaccine for Sars, for Mers, for HIV. There is a huge, huge, fantastic effort that has gone into this.

‘And when you consider the damage that this virus has done to human life across the planet, the economic damage, the social damage to say nothing of the cost in life and suffering, it is a fantastic moment.

‘But to repeat the key message, the worst thing now would be to think that this is the moment when we can relax our guard and think that it is game over in the fight against Covid. This is not. This is not the end.’

Professor Van Tam echoed a similar sentiment as he said: ‘I don’t mind telling you, I am not saying it for effect, the office will ell you it is true, that I was quite emotional this morning when I heard June Raine, Sir Munir Pirmohamed and Wei Shen Lim lay out how they had got very meticulously to their conclusions about the Pfizer vaccine.

‘And what a momentous journey and international effort it has been. Discovery by two scientists who originally lived in Turkey, development by a German biotech company, involvement of a massive US pharmaceutical giant and then involvement of our own UK MHRA to bring home the goods in terms of the UK. What a fantastic journey.’ 

Despite warning against over-optimism, Mr Johnson said it was now ‘sure and certain’ that life could start returning to normal in 2021.

Some 800,000 doses of Pfizer’s vaccine — which requires two doses being taken 21 days apart in order to be fully effective — will be made available from next week. 

The UK has pre-ordered 40million doses in total, with 10million due by the end of 2020 and the rest next year.

But there is growing confusion about which groups will get the first doses. The JCVI published its Covid-19 priority list this morning, advising that care home residents and the staff who treat them should be the first in line to be inoculated. 

However, officials warned they couldn’t promise care homes would get the vaccine before everyone else, admitting ‘whether or not that is actually doable depends on deployment and implementation’. 

Pfizer/BioNTech’s jab blocks 95 per cent of Covid-19 infections, according to trial results that shows it works just as well among over-65s, who are most at risk of the disease. 

But transporting and storing the vaccine poses logistical challenges because it must be kept in long-term storage at -70C. To keep doses of the jab at this ultra-low temperature, they need to be packaged with dry ice and placed in a special transport box the size of a suitcase which hold 5,000 doses.

These containers can prevent the vaccines from spoiling for 10 days if they remain unopened. 

Once the batches arrive at vaccination hubs, they can be stored in standard medical fridges at between 2C and 8C for up to five days. Or they can be kept in their shipping boxes for up to 30 days if the containers are topped up with dry ice at least once a week.

Fifty NHS hospitals in England are already equipped with super-cold freezers that can keep the vaccine at -70C, meaning healthcare staff could be inoculated first. However, there is a potentially major sticking point for roll out to care homes because BioNTech says that the vaccine can only be kept at between 2C and 8C for six hours in transit without going off. 

Because the Pfizer suitcases hold 5,000 vaccine doses, smaller quantities would have to be removed from the dry ice suitcases for transport to care homes. But once they are in transit the doses could perish after six hours.

Sir Simon said at the press conference that the vaccine ‘also comes in packs of 975 people’s doses’ which would be easier to move around but would still be too big to be stored at a single GP practice.    

Mr Johnson conceded that rolling out the vaccine to care homes will be difficult as he said: ‘The issue is, of course we want to get it into care homes to protect the most vulnerable as fast as we possibly can. The Joint Committee on Vaccination and Immunisation has rightly said that care home residents must be a priority.

‘The difficulty is in distributing the cases to care homes. Each case has 975 vaccines in it and obviously you want to avoid wastage and the difficulty is that the MHRA has not yet authorised the people who would be transporting the vaccine to the care homes to be able to effect the division themselves.’

Welsh Health Minister Vaughan Gething had earlier said the logistical issues meant ‘in practical terms at this stage that we cannot deliver this vaccine to care homes’.

The MHRA moved with unprecedented speed to approve the jab within just a week of receiving the final data from Pfizer’s phase three trials. The watchdog had been conducting a ‘rolling review’ of the vaccine, scrutinising data from its studies in real-time. MHRA chief executive Dr June Raine insisted that despite the rapid approval, the vaccine had been assessed ‘with meticulous care’ and ‘no corners had been cut’.   

The announcement comes on the day England emerged from its second national lockdown and came as figures showed Covid cases and deaths are continuing to fall, with another 648 fatalities and 16,170 cases as the second wave dies down.

In other vaccine developments on the back of Pfizer’s approval:

• Organised criminal gangs may capitalise on the approval of the new Covid vaccine by stealing supplies to sell on or peddling fake doses, Interpol warned;
• Comparisons between Pfizer’s vaccine and the Thalidomide scandal are ‘insulting’, a charity warned after the birth defect-causing drug began trending on Twitter in the wake of Britain approving the jab;
• Supermarket giant Iceland’s boss told No10 it ‘stands ready’ to help the UK deliver the Covid vaccine, saying the firm’s ‘cold chain expertise’ may be helpful in local distribution of the jab;
• Teachers, soldiers, and bus drivers could be first in line for a Covid vaccine once all over-50s and ‘at-risk’ Britons are protected, JCVI guidance suggests; 
• Matt Hancock claims Brexit helped Britain become first country in the world to approve a Covid vaccine ‘because European regulators were moving too slowly’;
• The Health Secretary says he’ll take the Covid vaccine live on TV to show it’s safe in attempt to quell any anxiety;
• Britain may still need a circuit breaker lockdown in January or February – despite roll-out of Pfizer’s 95 per cent effective jab beginning next week, top scientist warns; 
• The MHRA was so keen to approve Pfizer’s Covid vaccine that it responded to emails within ten minutes, according to Pfizer’s vice president for medical and scientific affairs;
• Britons given Pfizer’s Covid vaccine will get partial immunity within 12 days of the first dose, MHRA regulators believe;
• NHS workers in Leicester have received an email confirming Leicester racecourse will be transformed into a vaccination hub ‘as soon as the government says go’.

Ben Osborn, Pfizer’s UK country manager, said that delivery of the vaccine was happening ‘right now’.

He said: ‘As you probably heard from the Secretary of State, Matt Hancock, earlier this morning, the delivery schedule has already been put in place.

‘We are delivering right now as we speak from Belgium into the UK – that process has already begun.

‘We anticipate that we will be providing some 800,000 doses or so in the coming days, ready for deployment next week by the NHS.’

He said the pharmaceutical company was not ‘giving an absolute figure’ on the total numbers which would be delivered to the UK this year.

Mr Osborn added: ‘You’ll understand this is a significant challenge to deliver. But we will be in a position to deliver millions of doses in the weeks ahead.

‘That is part of a bigger scale-up, which will essentially allow the UK to have 40million doses of the Pfizer/BioNTech vaccine.’

Sean Marett, chief commercial officer at BioNTech, said the first consignment of its newly-approved vaccine could reach Britain as soon as tomorrow.

He told BBC Radio 4’s World At One programme: ‘We’re packing them now as we speak and getting ready for shipping. What we can definitely say is it will arrive, the first consignment, in the next few days and that could be as early as tomorrow or it could be a few days later, but the UK will be the first country in the world to be receiving vaccine for administration to its population.

‘We will probably be shipping several consignments to the UK over the next few weeks and it might be that the numbers vary on size of packaging that we put together in a lorry and then ship, so the UK has a good number of vaccines coming to it in December.’

Before the first batch of doses were sent to Britain, batches were checked at a central depot to ensure their quality. The vaccine will then be unloaded and moved to storage freezers where it will undergo an additional temperature check.

Public Health England (PHE) will process orders placed by the NHS for next day delivery to hospital hubs around the UK. Defrosting the vaccine for use takes several hours and then extra time is needed to prepare the vaccine for administering as doses. 

Health Secretary Matt Hancock — who admitted he was unsure how many people need to be vaccinated before restrictions can be lifted — told the Commons the first batch of the vaccine was completed this morning.

He said the rollout of the vaccine will be ‘one of the biggest civilian logistical efforts that we’ve faced as a nation’.

Mr Hancock told MPs: ‘It will be difficult. There will be challenges and complications, but I know that the NHS is equal to the task.’

He added: ‘We will deliver according to clinical prioritisation and operational necessity because of the need to hold the vaccine at minus-70 – it makes this vaccine particularly challenging to deploy.’

Mr Hancock said the roll out of the jab represented the start of a ‘new chapter in our fight against this virus’.

He said: ‘Ever since the pandemic hit our shores almost a year ago we have known a vaccine would be critical to set us free. It’s no longer if there’s going to be a vaccine, it’s when.

‘In our battle against the virus, help is on its way. Today is a triumph for all those who believe in science, a triumph for ingenuity, a triumph for humanity.’

Professor Wei Shen Lim, chair of the JCVI, told a Downing Street press conference this morning: ‘The advice is aimed at maximising the benefit from vaccines and therefore it is aimed at the most vulnerable people, which are people in care homes.’ 

He added: ‘Whether or not the vaccine can be delivered to care homes is a valid point and there will be some flexibility [with the priority list]. Every effort should be made to supply and offer the vaccine to care home residents. Whether that’s doable is dependent on deployment and implementation.’ 

At Prime Minister’s Questions at lunchtime, Mr Johnson admitted there would be ‘logistical’ issues in trying to get all care homes immunised first after being quizzed by Sir Keir Starmer.

The Labour leader asked: ‘What plans has he put in place to address these particular problems of getting the vaccine safely and quickly into care homes, given the practical difficulties of doing so and the anxiety that those in care homes will have about getting it quickly?’

Mr Johnson said: ‘It does need to be kept at -70C, as I think the House understands, so there are logistical challenges to be overcome to get vulnerable people the access to the vaccine that they need.

‘We are working on it with all four devolved administrations in order to ensure that the NHS across the country is able – and it’s the NHS that will be in the lead – to distribute it as fast and as sensibly as possible to the most vulnerable groups.’

Welsh Health Minister Mr Gething raised more doubts that care homes would be inoculated first this morning when asked about the vaccine’s deployment.

He said the Government in Wales had been exploring ‘suitable options for initial deployment of this vaccine’, but ‘in practical terms at this stage that we cannot deliver this vaccine to care homes’.

But Sean Marett, who is chief commercial officer at BioNTech and responsible for distribution, took issue with UK officials’ claims the Covid-19 vaccine would be a logistical nightmare to get to care homes.

He said: ‘We have stability studies now really supporting the evidence for being able to transport up to six hours at two to eight degrees, so you can really take vials from the vaccination centre – one of the large ones – put them in a bag at two to 8C and take them to the care homes where they can be administered directly to the patients.’

He added: ‘If you store the vaccine in a fridge, you can store it for up to five days. If you want to take some of those vials out of the fridge containing the vaccine, and ship them to a local care home, then you have to do that within six hours at two to eight degrees.’

Mr Marett said one option is pure storage where you take the vaccine out and use it for the patient, and the other is to put it in a van, and deliver those vaccines to a care home.

‘There you need to deliver within six hours, at two to eight and use the vaccine thereafter,’ he said.

Chancellor Rishi Sunak welcomed the news as ‘another positive step on our journey to beat this thing’ and paid ‘enormous tribute to everyone involved’.  

He said: ‘It’s a moment of great hope and opportunity, but there’s still work to do. We’ve got to get the vaccines, we got to roll them out. All that work is ongoing, people should feel reassured about that.’

Mr Sunak said he hoped the vaccine roll-out would boost consumer confidence, which was ‘critical’ for Britain’s economic recovery. ‘Hopefully, this is the start of a march back,’ he added.

Today’s announcement makes the UK the first country in the world to have a clinically authorised Covid-19 vaccine, which Professor Sir Munir Pirmohamed, of the Commission on Human Medicines advisory panel, described as an ‘historic moment’.

He told the press conference: ‘We are in the midst of a once-in-a-century pandemic and I think this is a historic moment. The UK is now one step closer to providing a safe and effective vaccine to help in the fight against Covid-19, a virus that has affected each and every one of us in some way. This will help to save lives.’  

Mr Hancock also hailed the news, saying: ‘We can see the dawn in the distance but we have to get through to the morning.’ Mass-vaccination is seen as the only way to put an end to the perpetual opening up and closing down of society through draconian lockdowns, which have had devastating consequences on the economy and wider health. 

Regulators today claimed Pfizer’s Covid vaccine offers ‘partial immunity’ within just twelve days of getting the first dose.

Professor Sir Munir Pirmohamed, chair of Commission on Human Medicine expert working group — which advises ministers on medicinal products, said that some protection occurs after receiving the first of the two-shot vaccine.

It offers a glimmer of hope that the roll-out of the vaccine beginning next week may have an effect before Christmas.

In a Downing Street press conference today, he revealed people ‘will be immune seven days after the second dose’ of the vaccine, which is taken roughly 21 days later.

Scientists remain unsure as to how long immunity against Covid lasts for, with fears protection may only be short-lived. But in-depth studies suggest that the majority of survivors will be able to fight off the disease within at least six months. 

Some experts have claimed people may need to be vaccinated against the disease every winter, like the flu.

MHRA chief executive Dr June Raine told the Downing Street briefing today that, despite the jab being approved in record time, the process had been done with ‘meticulous care’, adding: ‘That doesn’t mean that any corners have been cut, none at all.’

Dr Raine said experts had worked ’round the clock, carefully, methodically poring over tables and analyses and graphs on every single piece of data’. 

More than 1,000 pages of data had been examined, she said. Dr Raine added: ‘We have carried out a rigorous scientific assessment of all the available evidence of quality, safety and effectiveness. The public’s safety has always been at the forefront of our minds – safety is our watchword.

‘I’m really pleased to say that the UK is now one step closer to providing a safe and effective vaccine to help in the fight against Covid-19 – a virus that has affected each and every one of us in some way – and in helping to save lives.’We are globally recognised for requiring high standards of safety, quality and effectiveness for any vaccine.

‘Our expert scientists and clinicians worked tirelessly, around the clock, carefully, scientifically, robustly and rigorously poring over hundreds of pages and tables of data, methodically reviewing the data.

‘Vaccines are the most effective way to prevent infectious diseases. They save millions of lives worldwide.’

During a round of interviews this morning, Mr Hancock said: ‘The NHS stands ready to start vaccinating early next week. The UK is the first country in the world to have a clinically approved vaccine for supply.’

The Health Secretary urged England to abide by the controversial three-tier lockdown system that came into force today after being approved last night, saying although the end is in sight ‘we’ve got to keep people safe in the meantime’.   

He told BBC Breakfast: ‘From Easter onwards, things are going to be better and we’re going to have a summer next year that everybody can enjoy.’ 

In total, Britain will receive 10million doses of Pfizer/BioNTech’s vaccine by the end of the year, enough to inoculate 5million people, with the remaining 30million doses due in the first quarter of 2021. 

The UK has also ordered 100million doses of Oxford University’s Covid vaccine, with up to 19million ready to go by Christmas, and 5million doses of Moderna’s vaccine, which won’t be ready until spring.

The JCVI confirmed its priority list for the first phase of the UK’s mass vaccine roll out, with care home residents and the staff who look after them first in line, followed by frontline NHS staff and everyone over the age of 80.

Those above the age of 75 next in the queue, followed by over-70s, over-65s and high-risk adults under 65 with diseases such as cancer, with moderate risk adults under 65 – including diabetics and asthmatics – next. 

Over-60s will follow, with over-55s and over-50s the final priority groups. It is hoped every vulnerable Brit will be protected by Easter, which has raised hopes of returning to normality by spring.

The general population will be last to get their hands on a jab and the JCVI says they will be prioritised based on age or underlying conditions.

But in guidance published today, the JCVI has left the door open to the possibility of teachers, soldiers and bus drivers getting priority once all over-50s are jabbed.

Though the body said this will be an ‘issue of policy’ rather than one for it to advise on. 

‘Vaccination of those at increased risk of exposure to SARS-CoV-2 due to their occupation could also be a priority in the next phase,’ the guidance says.

‘This could include first responders, the military, those involved in the justice system, teachers, transport workers, and public servants essential to the 10 pandemic response.  

Priority occupations for vaccination are considered an issue of policy, rather than for JCVI to advise on. JCVI asks that the Department of Health and Social Care consider occupational vaccination in collaboration with other Government departments.’ 

Making the announcement this morning, a spokesman for the DHSC said today: ‘The Government has today accepted the recommendation from the independent Medicines and Healthcare products Regulatory Agency (MHRA) to approve Pfizer/BioNTech’s Covid-19 vaccine for use.

‘This follows months of rigorous clinical trials and a thorough analysis of the data by experts at the MHRA who have concluded that the vaccine has met its strict standards of safety, quality and effectiveness.

‘The Joint Committee on Vaccination and Immunisation (JCVI) will shortly also publish its latest advice for the priority groups to receive the vaccine, including care home residents, health and care staff, the elderly and the clinically extremely vulnerable.

‘The vaccine will be made available across the UK from next week.’ 

The first delivery of 800,000 doses of Pfizer’s vaccine is expected next week. The doses are being manufactured at a factory in Belgium. 

Mr Hancock told the BBC: ‘This is why it will take a couple of days from now before people can start to have it injected in their arms starting early next week. We’re expecting a matter of millions of doses for the whole of the UK by the end of the year.’

But he said the number delivered this year would depend on the speed of manufacture and how quickly they could be tested before dispatch. 

Mr Hancock added there would be ‘three modes of delivery’ of the vaccine and revealed 50 hospitals were equipped and ready to start dishing out the vaccines as soon as they arrive.

He told Sky News: ‘The first is hospitals themselves, which of course we’ve got facilities like this. Fifty hospitals across the country are already set up and waiting to receive the vaccine as soon as it’s approved, so that can now happen. 

‘Also vaccination centres, which will be big centres where people can go to get vaccinated. They are being set up now. 

‘There will also be a community rollout, including GPs and pharmacists. Now, of course, because of the -70C storage conditions of this vaccine, they will be able to support this rollout where they have those facilities.

‘But they’ll also be there should the AstraZeneca vaccine be approved because that doesn’t have these cold storage requirements and so is operationally easier to roll out.’ 

He added: ‘We’re the first country in the world to have a clinically-authorised vaccine to roll out.’

Mr Hancock also claimed Brexit helped the UK become the first country in the world to have a clinically authorised vaccine, telling Times Radio: ‘And the reason we’ve been able to move this fast, and the UK is the first country in the world to have a clinically authorised vaccine, the reason is twofold.

‘Firstly, because the MRHA has done a great job of working with the company to look at that data as it’s come through and do things in parallel, rather than one after the other as they normally would, that’s the first reason.

‘The second reason is because, whilst until earlier this year we were in the European Medicines Agency (EMA), because of Brexit we’ve been able to make a decision to do this based on the UK regulator, a world-class regulator, and not go at the pace of the Europeans, who are moving a little bit more slowly.

‘We do all the same safety checks and the same processes, but we have been able to speed up how they’re done because of Brexit.’ 

Mr Hancock this morning also offered to get vaccinated live on television to help convince people it is safe, amid fears up to a fifth of Brits will refuse the jab.

ITV’s Good Morning Britain presenter Piers Morgan made the suggestion before Mr Hancock said: ‘Yeah, I’ll take it with you, Piers’. 

The presenter said: ‘I’ll come to where you are anytime next week if we can do this. Let’s do it together, live on air. It would be powerful, it would send the right message.’

Mr Hancock added: ‘Well, we’d have to get that approved because, of course, there is a prioritisation according to clinical need and, thankfully, as a healthy, middle-aged man, you’re not at the top of the prioritisation.

‘But if we can get that approved and if people think that’s reasonable then I’m up for doing that because once the MHRA has approved a vaccine, they only do that if it is safe.

‘And so, if that can help anybody else, persuade anybody else that they should take the vaccine then I think it’s worth it.’

There have been reports that shops, restaurants and travel companies could require customers to present so-called ‘vaccine passports’ – proof they had been vaccinated – before using their services.

But Mr Hancock said that ‘isn’t part of our plan’, adding: ‘While we know that this vaccine protects you from getting ill with Covid – we don’t yet know how much it stops you transmitting Covid until we roll it out broadly,’ he told Sky News.

‘We will, of course, be monitoring that very carefully.

‘Therefore, we will vaccinate according to protecting the people who need the protection most, according to those who are vulnerable from Covid.

‘So, that is part of the plan. The plan is to get this rolled out, according to the clinical prioritisation that the advisers will set out.’

Reacting to the vaccine news, Chris Hopson, chief executive of NHS Providers, said: ‘This is great news. An effective vaccine – along with advances in treatment and rapid turnaround mass testing – presents real hope for a way out of the pandemic.

‘It’s reassuring to know that the regulator has reached this decision only after very careful evaluation of safety, quality and effectiveness. 

‘The logistics of administering the Pfizer/BioNTech jab are formidable, but the NHS has been preparing for this, and trusts will play a key role.

‘The health service has an excellent track record of delivering vaccination programmes – though this will be on an unprecedented scale, with added challenges because of the need to run mass vaccination centres and the requirement for cold storage. 

‘And while this announcement gives great cause for hope, it’s important to remember that this does not mean life gets back to normal – at least until the spring or early summer.

‘For the time being our best defence against COVID-19 is to prevent infection by observing lockdown restrictions. 

‘We’ll need that to get through the tough winter weeks ahead. But now at least we have the prospect of better days ahead.’

Scotland’s interim chief medical officer Gregor Smith tweeted: ‘Wonderful news that MHRA has approved the authorisation to supply Pfizer BioNTech coronavirus vaccine.

‘First of several vaccines in pipeline and begins to change everything for our future.’ 

Independent scientists hailed Pfizer’s approval as ‘momentous’ and a huge landmark in the global efforts to address this pandemic.’

Professor Arne Akbar, president of the British Society for Immunology, said: ‘This is a momentous day for us all. Covid-19 has impacted all our lives in so many ways and hope of an exit strategy has relied on a safe and effective vaccine.

‘It is only 12 months since the first case recorded case of COVID-19 and in that time, researchers around the world have worked tirelessly to increase our understanding of this new disease and develop safe and effective vaccines.

‘To achieve this within this timescale is remarkable and the researchers should be applauded. However this announcement is not the end of the story and there is still much work to do. Roll out of the vaccine is going to be a logistical challenge and rely on our dedicated healthcare professionals around the country.

‘Additionally, building public confidence in the vaccine is going to be crucial in ensuring the high uptake needed to stop the spread of SARS-CoV-2 within our communities. It is essential that we have high profile and multifaceted engagement campaigns that listen and respond to the public’s questions around the vaccine.’

Dr John Tregoning, reader in respiratory infections at Imperial College London, added: ‘This is great news and remarkable progress given the first cases were less than a year ago. It shows what progress can be made through science and innovation.

‘The MHRA, the UK drug regulator, will have gone through all the safety data from the trials before approving and will continue to monitor as it is rolled out more widely. 

‘The next step will be to get the vaccine to the people who need it the most.’ 

Dr Michael Head, senior research fellow in global health at the University of Southampton, said: ‘This is excellent news and a huge landmark in the global efforts to address this pandemic. The regulators have clearly been satisfied with the data presented to them.

‘The Pfizer vaccine does require storage at around -70C, which will pose significant logistical challenges for all countries that choose to use it. These are not insurmountable but certainly challenging. 

‘Other vaccines, such as the Oxford AstraZeneca candidate, require storage at much lesser temperatures and will be simpler to transport. 

‘Given we will certainly need more than one licensed vaccine to maximise global coverage, everyone will still be eagerly waiting for further developments from Oxford and Moderna. But, for now, this is wonderful news to wake up to.’

Oxford University’s coronavirus vaccine is expected to be given the green-light by the MHRA in the coming weeks and is likely to become the second jab approved in the UK.

That vaccine is expected to cost just £2 per dose and can be stored in ordinary equipment, unlike Pfizer’s that needs to be kept in ultra-cold temperatures using expensive equipment. 

From the moment the Pfizer vaccine leaves the factory in Belgium it can only be taken out of minus 70C four times before it is injected into a patient’s arm.

Oxford’s is also a fraction of the price, with Pfizer’s costing around £15 per dose and Moderna’s priced at about £26 a shot. 

Oxford’s trials found its jab has a nine in ten chance of working when administered as a half dose first and then a full dose a month later. 

However, efficacy drops to 62 per cent when someone is given two full doses a month apart.

However, even with a 62 per cent efficacy, that still puts the vaccine on par with effective influenza vaccines. The World Health Organization (WHO) has set a target of 50 per cent effectiveness for a Covid-19 jab.

The Oxford vaccine is based on different technology to Pfizer and Moderna’s candidates, which are known as ‘mRNA’, or messenger RNA, vaccines. 

Both use genetic material called mRNA which instructs human cells to make coronavirus spike proteins. 

Unlike Oxford’s vaccine, which is produced using weakened forms of the virus, RNA vaccines can be constructed quickly using only the pathogen’s genetic code. 

The new mRNA vaccines have never been approved by regulators before, whereas the Oxford approach has been used in vaccines for diseases such as tuberculosis, malaria, MERS and Ebola.

Despite the news, Britain may still need a circuit-breaker lockdown in late winter despite the promising vaccine news today, a top scientist warned. 

Liam Smeeth, professor of clinical epidemiology at the London School of Hygiene and Tropical Medicine, said although some vulnerable groups will be inoculated by this year, mass vaccination won’t happen for months.

He warned this gives Covid-19 weeks to proliferate during the deep winter months, when viruses spread more easily as people stay indoors more.  

Professor Smeeth said: ‘The continued progress on vaccines is fantastic news.

‘A route towards a much better situation in the UK is becoming clear.

‘But a further circuit-breaker in January or possibly February is likely to be needed.’

It was also revealed today that the MHRA was so keen to approve Pfizer’s Covid-19 vaccine that it responded to emails in ten minutes, according to Pfizer’s vice president for medical and scientific affairs.

Professor Ralph Reinet, who is an expert in infectious diseases at the American pharmaceutical giant, said the regulator was ‘very quick’ in asking for information when contrasting it to others including the European Medical Agency (EMA).

‘The world is looking at the UK at the moment,’ he said. ‘Sometimes a country needs to lead and the UK is leading.’

Some countries are taking longer to approve Pfizer’s jab because they use a ‘different process’ for ensuring vaccines are safe for distribution.

But many have been in touch today to ask how Britain has managed to approve the vaccine so quickly – although he refused to detail which countries.

Professor Berkeley Phillips, Pfizer UK’s medical director, described the vaccine approval process as like a book with three chapters – effectiveness of the vaccine, its safety, and the quality of its manufacture.

He said the MHRA was satisfied that Pfizer’s jab met the standard in each of these, so had issued it with an emergency approval.

There is only the administrative work of writing the contents page and the summary left to do, he said, which the regulator said could be skipped to get the vaccine administered to those most in need sooner given the devastating impact of the pandemic.

It was suggested other countries may be following a more drawn out process.

Revealed: EVERYTHING you need to know about Pfizer’s Covid vaccine, from the science behind how the 95% effective jab works, how it costs five times more than Oxford’s, and the list of the 50 hospitals ready to begin roll-out next week 

How many doses of the Pfizer has the UK bought?  

The UK has secured 40million doses of the Pfizer/BioNTech vaccine, with 10million due in the UK by the end of the year. Matt Hancock revealed 800,000 doses will be available next week.

Patients need two doses, meaning Number 10 has only secured enough doses for around a third of Britain. 

However, it is likely other vaccines, including one from Oxford University that the UK has bought 100million doses of, will be approved in the coming weeks and months.

How long does it protect you for?

Regulators today said there was evidence of ‘partial immunity’ just seven days after the first dose, offering a glimmer of hope that the roll-out beginning next week may have an effect before Christmas.

But they insisted the best immunity comes seven days after the second dose, which is given three weeks after the first.

It remains a mystery as to how long immunity against Covid lasts for, with top scientists warning that people may need to be vaccinated against the disease every winter, like the flu. 

How will a vaccine be rolled out?

Work was going on behind the scenes to ensure that NHS staff were ready to start delivering vaccines to the most vulnerable from the start of December. 

Nightingale Hospitals and sports stadiums have been prepared as sites for mass vaccination clinics, while GPs and pharmacists will also be involved in the mammoth Army-backed operation to deliver the jab.

Mr Hancock also told Sky News that ’50 hospitals across the country are already set up and waiting to receive the vaccine as soon as it’s approved’.   

New regulations allowing more healthcare workers — and NHS volunteers — to administer flu and potential Covid-19 vaccines have also been introduced by the Government. They will be supervised by a healthcare professional.

NHS England last night published its full contract specification for GP practices delivering Covid jabs.This stated that they must be able to operate from 8am to 8pm, seven days a week including bank holidays when required for reasons such as needing to use up supplies of a vaccine without wasting any.

A letter sent to all practices suggests that it may be necessary for some staff to vaccinate patients on Christmas Day. Vaccination sites are expected to be able to deliver at least around 1,000 jabs per week. The contract to vaccinate begins next Tuesday and GPs will be paid £25.16 for every two jabs they administer.

Volunteers without medical training can put themselves forward through the GoodSAM app to give injections working with St John Ambulance. The role description states: ‘Volunteer vaccinators will be trained to deliver a vaccination to a patient. They will also be ready to act if a patient has an adverse reaction.’

People are also being sought to act as vaccination care volunteers. They will help patients get to the right place for their jab and be on hand to provide first aid if anyone becomes unwell.

Volunteer patient advocates, the third type of helper, will ‘concentrate on the welfare of patients through their experience’. 

What type of vaccine is this?

The jab is known as a messenger RNA (mRNA) vaccine.

Conventional vaccines are produced using weakened forms of the virus, but mRNAs use only the virus’s genetic code.

An mRNA vaccine is injected into the body where it enters cells and tells them to create antigens. These antigens are recognised by the immune system and prepare it to fight coronavirus.

What are the advantages of this type of vaccine?

No actual virus is needed to create an mRNA vaccine. This means the rate at which it can be produced is dramatically accelerated. As a result, mRNA vaccines have been hailed as potentially offering a rapid solution to new outbreaks of infectious diseases.

In theory, they can also be modified reasonably quickly if, for example, a virus develops mutations and begins to change. mRNA vaccines are also cheaper to produce than traditional vaccines, although both will play an important role in tackling Covid-19.

Are there any downsides? 

One downside to mRNA vaccines is that they need to be stored at ultra-cold temperatures and cannot be transported easily.

Pfizer’s Covid vaccine must be stored at minus 70C — about four times colder than a household freezer — in special suitcase-like storage boxes. Special GPS trackers will mean that the temperature of the Pfizer/BioNTech vaccine can be remotely monitored to ensure it stays at the correct heat to keep it effective.

Details of how the vaccine could be transported and stored emerged following concerns that the NHS may face difficulties handling a vaccine which needs to be stored at minus 70C.

Chris Hopson, chief executive of NHS Providers, said: ‘The logistics of administering the Pfizer/BioNTech jab are formidable.’  

Mr Hancock said while rollout was not ‘easy’, he was confident that the NHS can deliver the vaccine despite the logistics involved.

Pfizer has designed a suitcase-sized container that will keep the doses at minus 70C for up to 10 days using dry ice.

Each of the containers, dubbed ‘shippers’, holds around 1,000 doses and will be fitted with thermal sensors to enable the pharmaceutical giant to track the location and temperature of the frozen vaccine vials.

The thermal shipping systems can be recharged with dry ice if needed, Pfizer said. Vaccines will be shipped by air and road, but not boat due to the time constraints.

And once the vaccine has been transported it can be stored in a fridge for up to five days at 2-8C – which is entirely feasible in a standard medicine fridge at a GP practice. 

Are they safe?

All vaccines undergo rigorous testing and have oversight from experienced regulators.

Some believe mRNA vaccines are safer for the patient as they do not rely on any element of the virus being injected into the body. mRNA vaccines have been tried and tested in the lab and on animals before moving to human studies.

The human trials of mRNA vaccines – involving tens of thousands of people worldwide – have been going on since early 2020 to show whether they are safe and effective.

Pfizer will continue to collect safety and long-term outcomes data from participants for two years.
