Coronavirus: When WILL vaccinations free Britain from lockdown?
Will April 7 be the day Britain vaccinates its way out of lockdown? UK is on course to finish injecting all over-50s on that day – but it could be much SOONER and there are ALREADY hints that Covid vaccine is working in elderly
- Last week the NHS vaccinated 345,000 people per day, on average – a rate of 2.4million people per week
- If this is sustained it will hit the 15million mid-February ambition on February 17 – just two days after the target
- MPs are pressing for a road map out of lockdown by Boris Johnson and his advisers acting cautiously
- Schools look set to begin fully reopening on March 8 but it could be weeks or months until lockdown ends
Britain is on course to vaccinate all over-50s by April 7 at the current rate of vaccination, Mail Online estimates reveal as debate rages through Government about when lockdown can be lifted.
It comes after ministers, Chris Whitty and and SAGE scientists today signalled that they want all over-50s to be offered an injection before society reopens.
The protection offered by one dose of coronavirus vaccine takes two to three weeks to kick in, the latest evidence suggests, meaning the UK would be on track for measures to be lifted at the end of April at the current rate.
However, if the UK vaccine drive accelerates from last week’s daily average of 345,000 people per day and is able to sustain its maximum rate of 600,000 doses a day, then the over-50s target could be hit by mid-March.
Anti-lockdown Tory MPs are pushing for measures including school reopening to be eased sooner, when the 15million most vulnerable people are vaccinated by mid-February, but Boris Johnson has ruled out any lockdown relaxation until March 8.
Mark Harper, chair of the lockdown-sceptic CRG block, said once the top nine groups are vaccinated restrictions should be lifted altogether. And former Cabinet minister Iain Duncan Smith told MailOnline: ‘The trouble is they are now being beaten up by the scientists. The scientists are giving them all sorts of new reasons why you can’t unlock.
‘Of course for the scientists it doesn’t make any difference really because they get paid anyway.’
Experts estimate that the effects of mass vaccination could start to show through in falling numbers of people being admitted to hospital in mid-February, and then significantly fewer people dying from March. They said there would also be an impact on infections, perhaps sooner, but this will be less noticeable.
One researcher, Leeds University’s Professor Daniel Howdon, said there appears to already have been approximately 25 per cent declines in death rates among over-80s since December, although it is not yet clear whether this is a result of vaccination.
At a rate of 345,000 first doses per day – the current average – it will take until February 17 to vaccinate all of the top four priority groups, and then the remaining 17million over-50s and at-risk people could be reached in 49 days, or seven weeks, by April 7. At an average rate of 600,000 per day from today onwards – something the NHS has shown itself to be capable of, but which would require a lot of things to go right such as constant supplies, perfect organisation and even faster rates as people start to need second doses from mid-March – the first four groups could be done by Februayr 11 and all over-50s by March 12
Analysis shared on Twitter by Professor Daniel Howdon, a health economist at the University of Leeds, suggested there appears to already have been approximately 25 per cent declines in death rates among over-80s, although it is not yet clear whether this is a result of vaccination. This graph shows how the death rate among 85 to 89-year-old people started declining in January even when the outbreak was around its peak, which he said could be linked to vaccine coverage
The Covid-19 Actuaries Response Group, an organisation of volunteer experts, said in January that the effects of the UK’s mass vaccine rollout would start to be seen in falling hospital admissions and deaths from mid-February, and then in reduced death rates from March. There would also be a drop in infection rates but this will be less noticeable. The research was produced before the vaccine programme hit its current speed, on January 11
University of Warwick research published in January, before the current vaccination data became available, suggested that if a vaccine could prevent 65% of transmission, as Oxford now says its vaccine does, the country’s death rate could be kept to the low hundreds per day or fewer from late March onwards if the rule of six is kept in place. The model is based on a large majority of the population having a vaccine with that level of effectiveness
But modelling handed to SAGE in January predicted that easing restrictions from mid-February will cause a third wave of coronavirus that will peak at more than 1,000 deaths a day.
However, while the rollout is expected to speed up, there is still a ‘bumpy’ supply chain and ministers insist ‘our limiting factor remains supply’, which Mr Zahawi said today was ‘becoming more stable’. Other barriers to full speed vaccination may be the fact that only some GP surgeries are working on Sundays, and people will start to need second doses from early March, which will limit the numbers of unique people who can be reached.
At least one more vaccine should also come into use in March – Moderna’s – with the possibility of Johnson & Johnson and Novavax jabs also getting approval before then.
The current rate of the NHS’s vaccination programme shows it is on target to hit its target of offering jabs to the 15million most vulnerable people by mid-February. Last week’s rate means it needs just two more weeks to get there.
Officials say they will ‘offer’ the vaccine to everyone rather than say they will successfully give it to them, because some are likely to refuse to have the jab and others won’t be able to have it for medical reasons.
The 15m people include everyone over the age of 70 as well as NHS and social care workers, and those with serious long-term health conditions that put them at a high risk of dying if they catch Covid-19.
Although they are the number one priority for the Government, there are now concerns that vaccinating them alone will not be enough to end the brutal national lockdown.
There are 17million people over the age of 50 who make up priority groups four to nine and who will need to be reached once the top four priority groups have been done.
At a rate of 345,000 first doses per day – last week’s average – this would take 49 days, or seven weeks. From February 17 that would mean they could all be reached by April 7.
At an average rate of 600,000 per day from today onwards – something the NHS has shown itself to be capable of, but which would require a lot of things to go right such as constant supplies, perfect organisation and even faster rates as people start to need second doses from mid-March – the first four groups could be done by February 11.
Then it would take just 29 days to reach the 17million outstanding over-50s and high-risk people; four weeks and a day, ending on March 12.
After the most at-risk groups have been vaccinated, the Government plans to offer jabs to everyone aged 18 and over in the UK. There will be around 21million of them left by this point, according to the JCVI.
SIGN OF DEATH RATES STARTING TO DECLINE IN OVER-80S, SCIENTIST CLAIMS
Professor Daniel Howdon, a health economist at the University of Leeds, revealed on Twitter that the fatality rate among over-80s appears to be falling fast in the wake of the vaccination programme.
He said: ‘All 80+ groups are showing quite big (~25%) falls in the CFR [case fatality ratio] vs 75-79 group. All very tentative for now but I think of interest.’
Professor Howdon, using Public Health England data, noted that the proportion of Covid-positive people over the age of 90 who were dying appeared to have dropped from 46.8 per cent at January’s peak to 34.7 per cent in the most recent week.
In 85 to 89-year-olds it fell from 40.6 per cent to 30.5 per cent, he said, in 80 to 84-year-olds it dropped from 32.9 to 24.4 per cent, and in 75 to 79-year-olds from 20.6 to 17.6 per cent.
A graph shared by Professor Howdon showed how the death rate among 85 to 89-year-old people started declining in January even when the outbreak was around its peak, which he said could be linked to vaccine coverage
He said that less pressure on hospitals or longer lags between people catching the virus and dying could account for these effects but also suggested it was ‘not too unreasonable’ to expect to see an effect from vaccines.
Over-80s have been getting vaccinated since December 8, with more than 80 per cent of them now having had a first dose.
Professor Howdon added he was ‘going to keep an eye on it. Even if this isn’t an effect now, if vaccination reduces deaths more than cases then we should see one soon enough.’
At the realistic 345,000-per-day rate this could be achieved in 61 days – from April 7 this would take until June 7.
At the hyper-fast 600,000 per day – which would likely be impossible by this point because millions of people would be having their second doses, soaking up most of the NHS’s daily capacity – it would take 35 days. From March 12, this would end on April 16.
The estimates are based on an unlikely 100 per cent uptake rate and on the country having a big enough supply to cope with the number of doses needed each day which, from March, will include second doses for people who got their first jab at the start of the programme.
Professor Chris Whitty, England’s chief medical officer, said at a Downing Street press conference last night that it now looks as though all over-50s will need to be immunised in order to stop hospitals loading up with Covid patients again.
He said: ‘If you look at the situation for people that have gone into hospital only 54 per cent of all the people who go into hospital are over that age [70].
‘So what this means is that once we vaccinated down to 70 and above – plus those who care for them, frontline NHS staff and frontline care workers – we should significantly reduce the number of deaths.
‘But we will reduce by a much smaller number the number of people going into hospital…
‘If we vaccinate all the way down to the people over 50, and those who have actually got pre-existing health conditions, you then get through virtually all the people who have a high chance of dying.
‘So this is around 98 per cent of those who die are in that group. Importantly around 80 per cent, just over 80 per cent of all of those who go into hospital.’
Professor Whitty added: ‘So the first wave which is the aim is to complete on the 15th of February we would expect a situation where we can stop a very high proportion of the deaths but rather a smaller proportion of the pressure on the NHS – those very large numbers in hospital.
‘As you go onto the next wave, down to those over 50 we have further in roads into reducing deaths and also significantly reduce the pressure on the NHS.’
Vaccines minister Nadhim Zahawi appeared to indicate this morning that the government is looking at the top nine risk categories as the trigger point for a widespread downgrading of measures. So far the PM has only said that he will unveil a route map out of lockdown on February 22, after the first four most vulnerable groups have been covered.
Mr Zahawi refused to give a date for when the nine categories in phase one of the rollout will be complete.
Meanwhile, SAGE member Professor Andrew Hayward gave a similar message as he said there could be a ‘significant return to normality’ after all over-50s are vaccinated.
‘Once the most vulnerable people, particularly those over 50 and those with chronic illnesses, are vaccinated then yes I think we can see a significant return to normality,’ he said.
However, Prof Hayward said he still hoped the UK will be ‘more or less back to normal for the summer’.
Experts have warned that lockdown must not be lifted too soon or an uncontrollable third wave of Covid could begin and kill thousands more people, smashing through efforts to protect the country with vaccines.
Warwick University experts on the Government’s SAGE committee said in a paper published last week that easing restrictions too soon could case deaths to spike back above 1,000 per day, even with effective vaccines in play.
They explained that even though the vaccines we have appear to work very well, not everyone can or will accept the jab, and no vaccine can ever protect 100 per cent of the people who do get it.
People who couldn’t be vaccinated for medical reasons – those who have an extremely weak immune system, for example – will not be protected, and neither will people who turned the jab down, or those in the proportion of people who it fails to protect. A 95 per cent effective vaccine, for example, would still allow five out of 100 people to get Covid-19.
The discovery that Oxford’s vaccine appears to cut the risk of someone catching coronavirus and passing it on by two thirds is promising and suggests it could slash transmission even between people with mild symptoms or none, which would dampen a third wave.
OXFORD JAB CUTTING TRANSMISSION ‘COULD SAVE TENS OF THOUSANDS OF LIVES’
Oxford’s Covid vaccine could save tens of thousands of lives because it can cut the likelihood of catching coronavirus and passing it on by around two thirds, scientists say.
Modelling produced by SAGE members from Warwick University predicted that more than 150,000 more people could die in 2021 if lockdown rules were lifted in March or April and vaccines did not stop people from spreading the virus.
But with a 60 per cent infection-blocking capability – slightly lower than the 67 per cent that Oxford claims its vaccine is capable of – this could be halved, saving tens of thousands of lives.
This is critical because uptake will not be 100 per cent and not everyone who gets the vaccine will be protected by it, meaning the virus will still be a danger to some.
Lifting lockdown after vaccinating people with jabs that don’t stop the spread, the Warwick experts warned, would lead to ‘an uncontrolled wave of infection in which only those successfully immunised will escape.’
Research published in January by the University of Warwick suggested that if a vaccine could prevent 65% of transmission, as Oxford now says its vaccine does, the country’s death rate could be kept to the low hundreds per day or fewer from late March onwards if the rule of six is kept in place. The model is based on a large majority of the population having a vaccine with that level of effectiveness
And even doing so with the Oxford vaccine rolled out to millions of people could still lead to a spike of 1,500 deaths per day if lockdown was lifted in February in exchange for the rule of six, or 2,000 per day if lockdown ends completely in July.
Looking at how the daily death counts could change over the course of 2021, the experts found that only vaccines blocking 85 per cent of infections, and a gradual release of lockdown rules over the course of the year, would stop thousands more from dying.
Jabs that block 60 per cent of infections might still allow the peak of daily deaths to hit 2,000 per day if lockdown was lifted gradually but completely from February to August, they found. The peak would likely come in September.
The daily death count would be closer to 2,500 with vaccines that didn’t block infections, or around 700 for ones that blocked 85 per cent. Those peaks would be earlier, in the summer.
On easing lockdown over the course of the entire year, into around December 2021, would lead to a peak of just under 1,500 deaths per day for the 60 per cent infection-blocking jab, with the peak in January 2022.
But the Warwick experts, in research produced before the vaccination programme hit its current levels of success, warned that at least 50,000 people are likely to die in 2021 and this could be much higher if rules are lifted too soon.
The wrote in their paper: ‘Even maintaining [early September] levels of NPI [non-pharmaceutical interventions; social distancing rules] control and having a highly efficacious vaccine we estimate over fifty thousand deaths are likely to occur from January 2021 due to the slow decline in cases from its current high level.
‘Early relaxation of control measures or low infection efficacy can lead to a pronounced subsequent wave of infection.
‘If we wish to completely lift all restrictions once both phases of the vaccination campaign are complete, we predict a substantial outbreak with a large number of associated deaths.
‘When the vaccine is not infection blocking, removing NPIs triggers an uncontrolled wave of infection in which only those successfully immunised will escape.’
They predicted that between 99,000 and 123,000 more people could die in 2021 if lockdown and social distancing come to an end, even in an ‘optimistic’ vaccine scenario.
In less gloomy news, however, some experts claim they are already starting to see the effects of vaccination in the death rates of the most elderly people in the country.
Professor Daniel Howdon, a health economist at the University of Leeds, revealed on Twitter that the fatality rate among over-80s appears to be falling fast in the wake of the vaccination programme.
He said: ‘All 80+ groups are showing quite big (~25%) falls in the CFR [case fatality ratio] vs 75-79 group. All very tentative for now but I think of interest.’
Professor Howdon, using Public Health England data, noted that the proportion of Covid-positive people over the age of 90 who were dying appeared to have dropped from 46.8 per cent at January’s peak to 34.7 per cent in the most recent week.
In 85 to 89-year-olds it fell from 40.6 per cent to 30.5 per cent, he said, in 80 to 84-year-olds it dropped from 32.9 to 24.4 per cent, and in 75 to 79-year-olds from 20.6 to 17.6 per cent.
He said that less pressure on hospitals or longer lags between people catching the virus and dying could account for these effects but also suggested it was ‘not too unreasonable’ to expect to see an effect from vaccines.
Professor Howdon added he was ‘going to keep an eye on it. Even if this isn’t an effect now, if vaccination reduces deaths more than cases then we should see one soon enough.’
Tory anger is mounting over ‘goalpost shifting’ on lockdown today as ministers and scientists suggested all over-50s should get vaccines before any ‘significant’ easing.
Pressure is growing on Boris Johnson to commit to a major relaxation of the draconian measures within weeks, after the UK’s rollout of jabs hit the milestone of 10million people covered.
But there is alarm that the bar for allowing the economy to get back up and running is being lifted, with dire warnings about the threat of mutant coronavirus added to concerns about the strain on the NHS.
Vaccines minister Nadhim Zahawi appeared to indicate this morning that the government is looking at the top nine risk categories – around 32million people – as the trigger point for a widespread downgrading of measures. So far the PM has only said that he will unveil a route map out of lockdown on February 22, after the first four most vulnerable groups have been covered.
Mr Zahawi refused to give a date for when the nine categories in phase one of the rollout will be complete.
Meanwhile, SAGE member Professor Andrew Hayward gave a similar message as he said there could be a ‘significant return to normality’ after all over-50s are vaccinated.
‘Once the most vulnerable people, particularly those over 50 and those with chronic illnesses, are vaccinated then yes I think we can see a significant return to normality,’ he said.
However, Professor Hayward said he still hoped the UK will be ‘more or less back to normal for the summer’.
There were claims today that Chancellor Rishi Sunak is again leading calls within Cabinet for lockdown to be eased as early as possible – in contrast to the more cautious tone adopted by Mr Johnson recently.
A supporter of Mr Sunak told the Telegraph: ‘Rishi is concerned that the scientists have been moving the goalposts in recent weeks. It’s no longer just about hospitalisations and protecting the NHS but cases and case numbers.’
They said Mr Sunak was adamant this third national squeeze must be the final lockdown and heralded it a ‘fat lady sings moment’ – the point at which Britain draws a line under a cycle of lockdowns for good.
Treasury sources played down the reports this morning, insisting those are ‘not things he has said’. But they were hailed by lockdown-sceptic Tory MPs, who said he was ‘quite right’.
Asked on Today whether the government was shifting the goalposts on when lockdown can ease, Mr Zahawi said: ‘I think you’ve got to make sure your vaccination programme has protected the top nine categories in phase one…’
He reiterated that the PM will set out a roadmap and the intention is for restrictions to loosen ‘gradually’ from March 8, starting with schools.
Mr Zahawi declined to give a date for when the first nine groups in the priority list will have received their vaccine, but said people could ‘do the maths’.
Speaking to BBC Breakfast, Nadhim Zahawi said: ‘We will set out our target (for vaccinating groups 5-9) after we have hit our February 15 target.
‘But you can do the maths. We did 600,000 in a single day – the deployment infrastructure that we’ve built can do as much vaccines as we get supply, so the limiting factor will be vaccine supply.
‘You can see that in the next 10 or so days, we’ve got to do another almost touching five million and so if we keep that rate up we will very quickly go down the list of the top nine.’
Pressed on whether that meant it would take another 35 days from February 15 to have jabbed all 31 million people in the first nine cohorts, Mr Zahawi replied: ‘That assumes the supply, so I don’t want to commit to a date without going through it with a very fine toothcomb with the whole team, because our limiting factor is the supply of vaccines ultimately.
‘With any manufacturing process, especially one that is new, there are challenges around that, as we’ve seen in Europe and as we saw in the early days in the UK as well.’
