Apocalyptic forecast of 4,000 coronavirus deaths a day could be FIVE TIMES too high and had already been proved wrong when government revealed it at weekend


The claim that 4,000 people could be dying from coronavirus by next month could be four or five times too high and not reflect the current situation, experts warn.

The shocking figure was presented by chief scientific adviser Sir Patrick Vallance in Saturday’s TV briefing where Boris Johnson announced the UK’s second lockdown.

But there are concerns that it’s out of date and inaccurate, with SAGE accused of ‘misleading’ the public and MPs by cherry-picking the scariest data.

Professor Carl Heneghan, of the Centre for Evidence-Based Medicine at the University of Oxford, said he ‘cannot understand why they have used this data’.

The forecast could be four or five times too high, he said, because it is based on there being an average 1,000 deaths per day in the UK right now. In reality the daily average was 182 per day October 22 and 28, according to Department of Health data.

The number, which appeared as the worst case on a graph with three other possible scenarios, was created by statisticians at the University of Cambridge and Public Health England who have since revised their numbers and lowered the possible numbers of deaths. The team’s forecasts are not published online, like some of their other work, but are sent directly to SPI-M, a sub-group of SAGE, to do with it what they choose.

A potential 4,000 fatalities per day if there are no changes to restrictions was almost twice as high as the second worst case, which put them at a touch higher than 2,000 per day.

The lowest estimates in the no-action scenario estimated deaths at just below 2,000 per day, and all were higher than the peak in the first wave, when the most deaths were recorded on April 8 (1,073).

Professor Heneghan told The Telegraph: ‘Our job as scientists is to reflect the evidence and the uncertainties and to provide the latest estimates.

‘I cannot understand why they have used this data, when there are far more up-to-date forecasts from Cambridge that they could have accessed, which show something very different.’

In a blog post, Professor Heneghan and Dr Dan Howdon, a medical researcher at the University of Leeds, explained that the project that created the 4,000-per-day estimate has been update twice since and downgraded the numbers.

It had been based on an estimate of 1,000 deaths per day on November 1, but there were really only 162 announced yesterday.

Alternative scenarios on Sir Patrick’s graph put the November 1 deaths at 486, 266 and 234 – all significantly lower.

And, Professor Heneghan and Dr Howdon pointed out, the Cambridge forecast has been update more than once since the version that was used in the meeting.

They wrote: ‘Since the first autumn update on October 12, two subsequent updates have substantially revised down the estimated number of deaths.

‘The October 12 update projected 588 deaths on October 30, and updates since have revised this down to 324 (October 21 for the 31st) and most recently 241 (October 28 for the 5 November).

‘This most recent update goes up to 15 November, when 497 deaths are projected.’

The graph that the chief scientific adviser presented in the briefing showed that deaths could peak in late December, but the updated model does not go that far into the future.

The trajectory, however, puts deaths at only a quarter as high as the 4,000-per-day forecast.

Professor Heneghan said, therefore, that the 4,000-per-day could be as much as five times too many and that more accurate, lower estimates were available before the briefing was held on Saturday.

He told The Telegraph: ‘I’m deeply concerned about how the data is being presented so that politicians can make decisions.

‘It is a fast-changing situation, which is very different in different regions, and it concerns me that MPs who are about to go to a vote are not getting the full picture.’

Conservative MPs said they were worried the forecasts were ‘misleading’.

David Davis told the newspaper: ‘The first responsibility of the scientific advisers to the Government is to give the truth to the public and not to cherry-pick the data.

‘This is a fairly major error on their part if they’ve used old data which effectively misleads the public.’

And Steve Baker added: ‘This evidence does appear to indicate that the death models are already wrong and by quite a considerable margin.’





Questions were first raised yesterday over the dossier that helped tip England into lockdown with its grim prediction of 4,000 deaths a day.

The projection by Cambridge University in conjunction with Public Health England (PHE) is thought to have drastically shifted Downing Street‘s thinking.

Paperwork unearthed by the Mail shows the Cambridge model uses a timeframe twice as long as the headline death toll published every day.

While the headline figure from the Government’s Covid dashboard is for deaths which occur within 28 days of a positive Covid test, Cambridge’s ‘nowcast and forecast’, on which the Downing Street data was based, collates deaths within 60 days of a positive result.

No one was available from Cambridge to comment last night.

The Department of Health also refused to release the official report.

But last night PHE said their model is one of ‘many’ that is sent in to the Scientific Advisory Group for Emergencies (Sage) and that these models can be ‘wide-ranging’.

Of the many slides presented at the press conference, the most startling was a graph entitled ‘England daily deaths if no changes in policy or behaviour’.

It revealed forecasts from institutions including Imperial College London, Warwick University, the London School of Hygiene and Tropical Medicine and Cambridge.

The Cambridge projection suggested England’s daily death toll could reach 4,000 during the height of winter – many more than at the peak of the first wave.

Imperial predicted around 2,700 deaths a day and other institutions gave estimates below 2,000.

They all indicated that the UK was on course for a higher death toll than any predicted in reasonable worst-case scenario planning.

The Cambridge and PHE estimation far exceeded the 800 deaths a day forecast from the Sage expert committee.

It is understood these models were in a document presented to Downing Street by scientific advisers last week, and contributed to the lockdown.

Tory MP Charles Walker said: ‘If it is the case that SAGE are not making this document public, it is extraordinary given that SAGE scientists fall over themselves to get on TV and radio to talk about their work and the importance of putting the UK into a deep freeze.

‘All information that is being used to support the lockdown should be put into the public domain as a matter of course and duty.’

During the press conference on Saturday, Sir Patrick Vallance said: ‘Different groups come up with different answers depending on their models, but what is clear from all of them, in terms of deaths over the winter, there is the potential for this to be twice as bad or more compared to the first wave.’

Other scientists have provided more conservative estimates. James Naismith, director of the Rosalind Franklin Institute and professor of structural biology at Oxford University, said: ‘We do not know yet how many infections per day have occurred this week that has just ended, but it is very likely to be above 60,000 infections per day.

‘Based on those figures, we should expect and not be surprised to see a rise in deaths to around 500 per day over the next three weeks until we start to see the new measures take effect.’

Yesterday the Government said a further 162 people had died within 28 days of testing positive for Covid-19, bringing the total to 46,717.

PHE also publishes a daily figure for how many people die within 60 days of testing positive for Covid, but this is not the headline figure which is used at the top of the Government’s Covid ‘dashboard’ and is not routinely reported.
