Commentary: Here’s why England is facing four more weeks of lockdown

BookmarkYORK, England: UK prime minister Boris Johnson announced on Jun 14 that the fourth and final stage of England’s lockdown easing, due to take place on Jun 21,would be delayed by four weeks.Now scheduled for Jul 19, stage four will see the removal of all remaining legal restrictions, allowing groups of more than six (or two households) to meet socially indoors, nightclubs to reopen, and businesses such as pubs and hotels to return to operating at full capacity.

This will be frustrating for everyone, but when looking at the data, the logic of the government’s decision makes sense.A key factor in decisions about restrictions in England has been the number of patients in hospital with COVID-19, as this affects the ability of the NHS to treat both patients with severe COVID-19 and also non-COVID patients.

From a peak in England of over 34,000 patients in hospital with COVID-19 on Jan 18, which was two weeks after the most recent national lockdown began, the number of patients in hospital had fallen to less than 800 by May 17, when the most recent round of lockdown easing took place (stage three).
This trend indicates both that the national lockdown was effective in reducing hospitalisations, as had been the case in the past, but also that the gradual unlocking in stages one and two (in March and April respectively) did not lead to a rise in hospital admissions.
This is despite the increased interactions allowed in these first two stages.AdvertisementREAD: Commentary: We have to live with an endemic COVID-19. Here's what that could look likeAt the same time, spring 2021 has also seen vaccines for COVID-19 being rolled out, beginning with the groups most at risk of requiring hospital treatment if infected. headtopics.com
The latest data indicates that two weeks after a first dose of a vaccine, a person is 75 per cent less likely to require hospital treatment for COVID-19 than an equivalent unvaccinated individual. Two weeks after a second dose, this reduction increases to around 94 per cent.
Vaccine take-up has also been extremely high. On Jun 13, nearly 79 per cent of adults in England had received a first vaccine dose and over 54 per cent a second. The coverage of protection is greatest among the most vulnerable, with over 90 per cent of the over-60s being fully vaccinated.
So far, so positive. But problematically, there has also been an upward trend in the number of cases and the number of patients in hospital with COVID-19 over the past month.Get CNA’s Evening Brief newsletterStay on top of major news and announcements made through the workday.

The latest Public Health England analysis (released as a preprint, meaning it has yet to be formally reviewed by other scientists) suggests the Delta variant is around 60 per cent more transmissible than the previously dominant variant, Alpha.VACCINES BREAK THE LINK
A mitigating factor is that the vaccine programme has been effective in weakening the link between overall case numbers and hospitalisations. Data shows that the recent rise in cases is strongest among younger people, who are less likely to be fully vaccinated.

In contrast, the rise in cases in the over-60s is much smaller, a little less than twice what it was in early May, which mirrors the rise in hospitalisations, also up by a similar amount.

(AP Photo Jon Super)It therefore appears sensible to pause further relaxations of restrictions at this point to allow more vaccines to be given before moving to stage four. This should reduce and ideally overturn the current upward trend in hospitalisations.
By Jul 19, England is aiming to have offered all adults a first vaccination and everybody aged over 50 a second vaccination. This goal is likely to be exceeded given the current pace of the vaccine rollout: Over 70 per cent of over-50s have already had two doses.
People in their 40s, with less than 50 per cent fully vaccinated with both doses, is the main group with room for improvement. Although COVID-19 poses the greatest risk to the elderly, vaccinating younger groups like this should still have a good impact on reducing hospitalisations.
Before the vaccine rollout got going, approximately 20 per cent of patients admitted to intensive care with COVID-19 were under 50. Most were patients in their 40s.READ: Commentary: Privacy in a pandemic — can I ask my GP if they’ve been vaccinated for COVID-19?
A further four weeks also comes close to the beginning of school summer holidays, and so the extension is expected to reduce transmission without impacting further on education.While the final removal of restrictions may still lead to an increase in infections and hospitalisations, SPI-M – the government’s modelling group – has predicted that the peak of this wave would be reduced by between one-third and one-half by waiting four more weeks to relax restrictions.
While the announcement on Monday indicated Jul 17 would be the day of final and irreversible reopening, it may be most prudent to continue to follow the data rather than the dates. The key goal should be to maximise vaccinations in the adult population before this final step is taken.Read more: CNA »
