Chris Whitty defends ‘morbid’ SAGE worst-case models

Sir Chris Whitty today defended worst-case scenario Covid models pumped out during the pandemic.

Doomsday forecasts are vital for planning purposes, the chief medical officer told the Covid Inquiry.

Although Sir Chris accepted assumptions can be morbid, he insisted the potential death tolls cited during the darkest days of the crisis allowed officials to prepare in case they came to fruition.

It gave ministers chance to work out where they were ‘going to bury the bodies’, he said. 

Horrifying predictions of upwards of 500,000 deaths spooked No10 into declaring the first lockdown in March 2020.

Vaccines — considered the only safe route out of the pandemic — were still months away from being deployed. 

But the restrictions had huge knock-on effects, crippling the economy and causing huge backlogs within an already overwhelmed NHS.

Sir Chris, who took over in the role as CMO in October 2019 just three months before Covid officially began, made the statement during his evidence to the Inquiry today. 

Questioned by lead counsel Hugo Keith KC about ‘worst case’ scenarios put together by experts and presented to the Government, Sir Chris — who’s nicknamed Dr Doom in some corners — defended the practise. 

‘It is sensible to have a plan for if everything fails what are we going to do,’ he said. 

‘We do still need to be able to say, “let’s go to the top of the range, actually we could end up with 750,000 people dying, where are we going to bury the bodies”.’

Sir Chris added: ‘These are important, they may seem morbid, but they’re practically important planning.’

Morbid predictions from scientists have come under huge scrutiny.

One which has drawn particular focus is modelling by SAGE expert Imperial College London epidemiologist Professor Neil Ferguson, dubbed Professor Lockdown.

It warned 510,000 people could die from Covid if ministers didn’t act in early 2020.

Imperial College London published a paper in March 2020 on the potential impact of coronavirus. It weighed up options on how a lockdown could reduce demand on hospitals

That specific model, which critics have since labelled as flawed, is single-handedly credited with spooking ministers into banishing Britons into lockdown to thwart the spread of the virus.

It added that trying to ‘mitigate’ the spread – allowing it to continue but attempting to slow it down with limited measures such as isolation for those with symptoms — would have halved it to around 260,000.

It showed that mitigation would not be insufficient to prevent the NHS becoming overwhelmed by looking at bed capacity.

If the strictest possible measures are introduced – including school closures and mandatory home quarantine – the number of deaths over a two-year period will fall below 20,000, the scientists said.

Britain’s current Covid death toll stands in the region of 220,000. 

Other models were also heavily disputed, including one terrifying 4,000 deaths per day chart presented at a Downing Street press conference.

Scientists not involved in guiding the Government’s response claimed they failed to account for basic behavioural changes and underestimating the strength of natural immunity.

It is not the first time the Government’s top scientists have defended gloomy Covid data.

Cambridge and PHE  predicted the daily death toll could reach 4,000 at one point in the pandemic. This was heavily criticised, however

Sir Patrick Vallance, No10’s former chief scientific advisor, admitted in 2020 his ‘regrets’ over frightening people with a doomsday dossier that forecasted 4,000 Covid deaths a day over that winter and which was used to justify a second national lockdown.

He made the comments alongside Sir Chris when the pair were hauled before MPs to defend SAGE’s modelling that also predicted hospitals would be overrun with virus patients by the end of November that year.

At the time Sir Chris conceded that the 4,000 daily deaths prediction was unlikely to come true because the modelling was a worst-case scenario based on a situation where no extra measures were brought in. 

But the experts defended the science behind the gloomy forecast and said it was realistic to expect levels seen in April would be surpassed at the peak of a second wave, unless there was a lockdown.

WHAT DID PROFESSOR FERGUSON’S WORK SAY? 

The scientific paper published by Professor Ferguson and his colleagues on the Imperial College COVID-19 Response Team was credited for persuading Boris Johnson’s Government to ramp up their response to the coronavirus.

The paper, released on March 17, and titled Impact of non-pharmaceutical interventions (NPIs) to reduce COVID19 mortality and healthcare demand, predicted that the Government’s original plan to ‘mitigate’ the outbreak instead of trying to stop it could have led to a quarter of a million people dying.

Using data from Italy and China, the scientists predicted how different Government measures would have different impacts on the outbreaks. 

If no action at all had been taken against the coronavirus it would have claimed 510,000 lives, the team’s report said. Had the Government stuck with their strategy of trying to ‘mitigate’ the spread – allowing it to continue but attempting to slow it down – with limited measures such as home isolation for those with symptoms this number would be roughly halved to 260,000. 

If the strictest possible measures are introduced, the number of deaths over a two-year period will fall below 20,000, the scientists said.

Other points in the Imperial College report, titled Impact of non-pharmaceutical interventions (NPIs) to reduce COVID19 mortality and healthcare demand, included: 

  • Lockdown measures could be brought back if the virus resurfaces after this epidemic is over
  • The coronavirus outbreak is worse than anything the world has seen since the 1918 Spanish Flu pandemic 
  • Dramatic measures to suppress an outbreak carry ‘enormous social and economic costs which may themselves have significant impact on health and well-being’
  • Virus transmission happens evenly – one third of cases are caught in the home, one third at work or school, and one third elsewhere in the community
  • People are thought to be infectious from 12 hours before symptoms start, or from four days after catching the infection if someone doesn’t get symptoms
  • Patients who do get symptoms are thought to be 50 per cent more infectious than those who don’t 
  • People are thought to develop at least short-term immunity after catching the virus, meaning they can’t catch it again
  • Approximately 4.4 per cent of patients need hospital care. 30 per cent of those need intensive care, and 50 per cent of intensive care patients can be expected to die, according to data from China
  • The average length of a hospital stay for a coronavirus patient is 10 days – eight days for those who recover quickly; 16 days for those who need intensive care

It comes Sir Chris was repeatedly told to slow down by officials as he gave evidence on the country’s preparedness for the pandemic. 

As stenographers struggled to keep up with him, he joked ‘my enthusiasm is running away with me’.

Sir Chris also slammed the abuse some members of the public had levelled at the scientists who stepped forward to advise the Government.

He called the abuse targeted at independent scientific advisers ‘extremely concerning’ and told the probe the UK should be ‘very firm’ in saying it ‘appreciates the work of these people’.  

‘The level and abuse and in some cases threats to people who volunteer their time is an extremely concerning one and one we should be very firm in saying that society very much appreciates the work of these people, who put in considerable amounts of time, usually for no recompense,’ he said.

As the face of the NHS’s virus battle, Sir Chris alongside other prominent prominent scientists including Sir Patrick Vallance and Professor Neil Ferguson, were both championed and criticised by Britons. 

Sir Chris was himself a victim of such abuse, at one point being held in a headlock and jeered at by thugs who filmed the encounter. 

He also told Mr Keith: ‘We – society – need to ensure scientists know their service is valued.’ 

Sir Chris opened his evidence this morning by addressing the families bereaved by the pandemic, and referred to his first-hand experience of being on the Covid front line for 12 weeks.

Sir Chris said: ‘I can say to the families who are here I saw the extraordinary impact and devastation for individuals and the families.’

Later he also revealed the county’s science advisory system may struggle between emergencies. 

Under questioning from Mr Keith, Sir Chris said: ‘There are a number of bodies which give advice irrespective of whether there’s an emergency or not.

‘Some of those are relevant in emergencies, if they happen in their area of work.

‘Also, and I think this is important, in the way we think about it as a co-ordination mechanism for how to prioritise the advice that’s given.’

He added: ‘I think that there are no structural problems that I think need to be changed.

‘However, I think what this did demonstrate was that whilst the system can be extremely fast-moving during an emergency, I think it is sometimes less well co-ordinated between emergencies, and I think from that some problems actually arose.’

As many as 70 witnesses will contribute to the first module on pandemic preparedness. 

Former health secretary Matt Hancock, ex-Scottish first minister Nicola Sturgeon and the chief executive of the UK Health Security Agency Dame Jenny Harries will be among next week’s witnesses.

Mr Hancock is expected to give evidence on Tuesday while Ms Sturgeon and her former deputy John Swinney will appear on Thursday.

Dame Jenny, a former deputy chief medical officer for England, will also appear on Monday.

The first module will run for six weeks, until 20 July. The probe is not expected to conclude until 2026.

A separate Scottish Covid-19 Inquiry chaired by Lord Brailsford is looking at the pandemic response in devolved areas in Scotland.

Welsh First Minister Mark Drakeford has said he and the Welsh government are fully committed to the inquiry, though they maintain that there is no need for Wales to hold its own inquiry.
