Coronavirus UK: Public might abandon lockdown rules early if they think they are immune, SAGE warns

People might start socialising and ditching lockdown rules ahead of schedule if they think the Covid threat is low or believe they are immune, SAGE has warned.

Scientists advising the Government say people have been good at following rules so far but caution that the public will need reminding of why it is important to stick to them in the coming months.

In a paper dated February 10, the SAGE subgroup SPI-B, which is made up of experts on human behaviour, said official messaging will likely become ‘complicated’.

The success of the vaccination programme would lead many people to believe that breaking lockdown is increasingly less likely to lead to people dying, they said.

And the hardest social distancing rules – not visiting friends and family – might be the first to go out of the window. 

The experts warned: ‘Vaccination may lead to lower adherence to protective behaviours in people who have been vaccinated and, potentially, others in the population who perceive that there is no longer a major risk to vulnerable people.’

This was more likely to happen among younger people, the experts said, and older adults are likely to be more ‘cautious’ about returning to normality, potentially needing extra advice or reassurance on safe ways to do things.

People in England will still have to wait another month or more before visiting their friends and family again, with the Rule of Six set to come back in on March 29.

Under Boris Johnson’s roadmap out of lockdown, which he insists will be a ‘irreversible’ this time, outdoor mixing could be allowed in around a month’s time, followed by shops and gyms reopening in April and then large groups outdoors or six people indoors from mid-May. Rules will remain until at least the end of June.

The Prime Minister said on Monday that there is 'no escape' from the fact that cases, hospital admissions and deaths from Covid-19 will surge again in the country's inevitable third wave as lockdown is lifted for what he says will be the last time

The paper released publicly today was produced by SPI-B, the Scientific Pandemic Insights Group on Behaviours, which then gave it to government advisers, SAGE. 

It stressed the important of ‘maintaining public trust’, giving ‘clear guidance’ and having ‘a good communication campaign’.

Following lockdown rules is relatively easy, SPI-B explained, because they are blanket rules for everyone and basically ban everything except going to the supermarket.

But as rules become partly loosened, ministers will have to make extra efforts to explain to people why some restrictions are still necessary but others aren’t.


Tory MPs have called for Boris Johnson to bring forward the lockdown end date of June 21 and give millions of people their freedom before the summer solstice. 

But the Prime Minister was defiant on a visit to Accrington Academy in Lancashire yesterday, saying the number of people in hospital with Covid remains ‘high’.

Asked whether there was ‘wiggle room’ to lift lockdown quicker, he said: ‘I think it’s very important to have a timetable that is sensible, that is cautious, but one that is also irreversible. And that’s the virtue of the timetable we have set out.’

Despite promising early information about the impact vaccines have on reducing transmission of the virus, the Prime Minister said case numbers were still too high to accelerate easing the lockdown.

‘We’re sticking to our plan. Obviously we will continue to look at data but the data currently still shows, as you know, that the incidence of the disease, sadly, remains high,’ he added. ‘I’m afraid the numbers of people in hospital are still not far below the peak that they were in April last year.

‘So we think that the road map that we’ve set out is a good and balanced one for us to get on a journey that is cautious but, as I say, irreversible as well.’ 

Earlier in the week the PM admitted that even his apparently conservative date for lifting lockdown would lead to thousands more deaths from Covid-19.

SAGE has repeatedly warned that a third wave will be massive because millions of people – including the vast majority of children and teenagers – will still be unprotected despite a mass vaccination programme.

On Monday the PM said there was ‘no escape’ from the fact there would be a coronavirus resurgence when lockdown ends.

He said: ‘We’re now travelling on a one-way road to freedom and we can begin safely to restart our lives, and do it with confidence.

‘And I want to be frank about exactly what that means and the trade-offs involved.

The vaccines reduce the danger of Covid, they save lives and they keep people out of hospital. But no vaccine against any disease has ever been 100 per cent effective.   

‘So, whenever we ease the lockdown – whether it’s today or in six or nine months – we’ve got to be realistic and accept that there will be more infections, more hospitalisations and therefore, sadly, more deaths, just as there are every year with flu.

‘Even if we sustained the lockdown indefinitely, which would itself cost lives and do immeasurable harm to our children, we would not be able to eradicate this disease.

‘And that’s why it’s right, gradually, to replace the protection afforded by lockdown, with the protection of the vaccines. And our approach is to move with the utmost care.’

The paper said: ‘As interventions are lifted, communication will shift from a relatively straightforward “stay at home” message to a more nuanced set of messages about a range of activities. 

‘Messaging may be complicated by differences across tiers that change over time and complicated still further if immunity or vaccination certificates provide exemptions for some people, for some activities.’

The danger of people not appreciating the importance of rules could be that they stop following them too soon, SPI-B said.

Boris Johnson has laid out a timeline for relaxing measures gradually, leaving a gap of five or more weeks between each stage so officials can monitor the effects they have.

But people might start to bend the restrictions early if cases go very low and tens of millions of people have been vaccinated, the experts said.

More than 18.7million people have had at least one dose of a jab already, and other scientists on SAGE estimate between 20 and 40 per cent of the population already has some level of immunity to Covid-19 by now.

By mid-April, as many as 32million people may have been vaccinated – half of the population – and the three-month lockdown will likely have brought infections, hospital admissions and deaths grinding to a halt.

The outbreak was manageable in the summer last year, allowing for a lot of social freedoms, and early signs suggest this year will be even better. 

But SAGE remain concerned that children and teenagers will not have been immunised, and the vaccines don’t protect everyone who gets them.

A third wave is inevitable, they warn, and it will likely be huge, allowing the R rate to soar higher than two and likely killing tens of thousands more people. 

The paper said: ‘As perceptions of immunity grow, messaging may need to explain why continued adherence to specific protective measures is important. 

‘Unless a good communication campaign is in place, vaccination may lead to lower adherence to protective behaviours in people who have been vaccinated and, potentially, others in the population who perceive that there is no longer a major risk to vulnerable people. 

‘In addition, 16% of the general public believe they have already had COVID-19. 

‘This belief is associated with perceptions of immunity and lower adherence to several recommended behaviours. 

‘At the moment, the presence of national restrictions means that people who believe they have some immunity have a reduced opportunity to interact with others. As restrictions change, lower adherence to some recommendations may become apparent. 

‘This is more likely for those behaviours that are difficult for people to adhere to, for example restrictions to seeing family or friends. 

‘The extent to which this will be offset by increased immunity is uncertain. As restrictions change, messaging should be careful to ensure that the importance of continued adherence to protective measures is well explained.’  

Despite the warning, SPI-B said there were reasons to be hopeful because the public has been good about obeying lockdowns in the past. 

They added: ‘Surveys show the population supported the recent national lockdown and believe that it should have been introduced at an earlier point to prevent transmission. 

‘Therefore we have high confidence that the public will support a proportionate, gradual easing of restrictions.’
