Ministers and government scientists are drawing up what they hope will be a “three stage” approach to easing the coronavirus lockdown restrictions in the UK in phases between May and July, sources with direct knowledge of the plan told BuzzFeed News.
The strategy will depend heavily on significant improvements in infection rate data over the next three weeks, Britain dramatically increasing its testing and contact tracing capacity, tens of millions of people downloading a new NHS app, the efficacy of antiviral drugs at reducing symptoms of COVID-19, and strict measures remaining in place for elderly and vulnerable people until a vaccine is found.
- A “best case scenario” being worked on by the Scientific Advisory Group for Emergencies (SAGE) hopes to end lockdown restrictions for certain non-essential shops and industries in the short-term, from early to mid-May.
- Some social distancing measures could then gradually be relaxed in the medium-term, in June and July, eventually leading to the reopening of pubs and restaurants towards the end of the summer.
- Long-term “shielding” for elderly and vulnerable people could mean the public being told they face limits on seeing over-70s parents or grandparents for as long as 12-18 months until a vaccine is found.
- The timeline relies on SAGE scientists calculating how many new COVID-19 infections per day the UK’s test and trace capabilities can manage, and an “impossible” political decision for Downing Street on how many deaths per day they are willing to accept in order to be able to lift some restrictions before there is a vaccine.
No exact plan to relax the lockdown has been finalised, government sources told BuzzFeed News, because it was too early to take decisions without knowing if the transmission rate of the virus, “the R number”, was coming down to a manageable level, and whether proposals to test and trace potential cases were viable. If either of these did not go to plan, restrictions would have to be extended again or reintroduced at a later date, they warned.
The Treasury also wants to let as much of the manufacturing and construction industries get back to work as possible, while encouraging proper hygiene and social distancing in the workplace.
People would be allowed out of their homes for non-essential shopping in this scenario, but most social distancing measures would remain in place. Some ministers are lobbying Downing Street to partially relax some other of the harshest rules in this first stage, such as those stopping people from sitting in parks or taking more than one form of exercise a day.
Commuters could be encouraged to wear masks on public transport, if a review of scientific advice that is currently taking place finds them to be effective at preventing the spread of the disease.
SAGE scientists are also looking at lifting restrictions by age, raising the prospect that people under a certain age threshold could be able to go back to their offices sooner, organise social gatherings or go to the pub, but those above the limit cannot.
Ministers and aides believe the development of new treatments for COVID-19 and the repurposing of existing antiviral drugs could have an important role in allowing the UK to move to stage two. Aides have been optimistically sharing news in their WhatsApp groups this week that a drug called “remdesivir” has shown signs of alleviating symptoms in patients in the US. There is now increasing optimism in Whitehall that, by the summer, antiviral drugs could be used in Britain to give coronavirus patients a better chance of recovery and reduce death rates.
The third stage is the long-term final “exit” from the coronavirus crisis, when it is defeated once and for all and life returns to normal for the whole nation.
Government scientists have told ministers that there are only two routes to fully beating the virus: developing a vaccine, or the controversial “herd immunity” approach whereby a majority of the population get the disease, recover and can return to normal life.
Neither is a realistic prospect any time soon, with a vaccine thought to be a year to 18 months away — although scientists at Oxford university claim they could produce one by September — and doubts about how long immunity lasts. Until one of those two outcomes is achieved, the elderly and vulnerable must continue to be “shielded” with as many of the social distancing measures remaining in place as possible, a minister told BuzzFeed News.
Government figures are concerned that the public has not fully grasped the prospect of an effective indefinite lockdown for the over-70s and vulnerable groups. “‘You can’t see granny for 18 months’ is going to be an extremely unpopular and difficult policy to enforce,” the minister said.
Whitehall insiders point to several areas of concern. Hancock is prioritising an NHS app that would use bluetooth technology to flag up on people’s phones if they have been in contact with someone with coronavirus symptoms, and tell them to get tested. But government aides believe that in order for the app to be effective, it needs to be downloaded by 60% of the population, a task that some fear will be extremely difficult to pull off.
Officials are looking at how to enforce use of the app, potentially even requiring people by law to have it on their phones if they want any lifting of lockdown restrictions to apply to them.
There are also worries that the UK has again been too slow to hire an army of contact tracers that will be necessary to complement the app. This week, BuzzFeed News reported on concerns that the app will not work unless it is accompanied by mass testing and human-led contact tracing, areas where Britain is currently falling short.
The efficacy of test and trace as an exit strategy is also dependent on the rate of new COVID-19 infections, the government’s scientists have told ministers. Put simply, test and trace is not viable if more people are being infected each day than the health system has capacity to test and trace.
The government’s target of 100,000 tests per day means the rate of new infections would likely have to be in the low thousands for sufficient testing and tracing to be able to take place. On Friday, there were 5,559 confirmed new coronavirus cases in the UK, with many more likely getting the virus but untested. If the rate of new infections surpasses the capacity to test and trace, the government would be unable to lift lockdown restrictions for fear the virus would again become untestable, untraceable and uncontrollable.
The hardest decision for Downing Street is that it has to ultimately look at the data gathered by scientists on the rate of new infections, divide it by a hundred to come up with an estimate for likely new deaths, then take a political decision on whether that number is low enough for them to justify relaxing some of the lockdown measures.
For example, if there are 1,000 new infections taking place per day, at a mortality rate of around 1%, that is likely to mean around 10 new deaths from COVID-19 over the following two weeks.
Regardless of how well set-up the UK is on testing and tracing, Number 10 will have to make a judgment call on whether keeping the British economy alive justifies lifting some restrictions and tolerating those deaths. This decision was described to BuzzFeed News by one minister as “impossible”.

I am indebted to a friend on mine currently “Shielding” in Scotland for sending me this article. We are both technically “elderly & vulnerable”, and we agree that self -isolation for 12-18 months and not seeing our children and grand-children until a vaccine is found, is totally unacceptable.
It should be possible for Health Economists to calculate the “cost” of the “impossible decision” on the level of continuing acceptable deaths after the lifting of restrictions, using the concept of QUALYS – quality adjusted life years. The decision is not “impossible” and can be easily quantified in terms of economic cost in terms of the greater good for the population.
