My Lords, over the past few months, the Government have made a concerted effort to bring forth a sense of normality across the country with the easing of restrictions, while maintaining caution with regard to this deadly virus, which clearly has a long way to run. These regulations are a key part of this dual-track effort, significantly reducing the burden of self-isolation while protecting society from the threat of contagion. The main focus of the regs is the isolation protocols, so I begin by reflecting on the crucial role that contact tracing and self-isolation play in fighting the virus.
Since it was established in May 2020, NHS Test and Trace has contacted more than 15 million people who have tested positive for Covid-19 or who have been in contact with a positive case. Tracing—the bedrock of any public health intervention—has improved substantially over the last several months. In October 2020, 60% of close contacts were being reached. In comparison, over the period from 26 August to 1 September, 87.3% of positive cases transferred to NHS Test and Trace were reached, as have 89.5% of their contacts where usable contact details were provided. That is a remarkable achievement.
The public realise the importance of isolation. July’s ONS statistics that show 79% of positive cases reported complying with the self-isolation guidance, alongside 89% of close contacts. That is a terrific response from the public and it has proven a vital weapon in our arsenal against the virus.
What is the impact of this massive financial and societal investment? A recent study from PHE, published today and called the Canna model after the idyllic Scottish western isle, which some noble Lords may have visited, shows that from August last year to this April, test, trace and self-isolation activity reduced the transmission of the virus by between 10% and 28%. The PHE research demonstrates that self-isolation helped to bring R below one at crucial times, reducing the duration and impact of lockdown. Over the full period of the study, the Canna model estimates that isolation due to test, trace and isolate policies prevented
between 1.2 million and 2 million secondary cases. The NHS Test and Trace service has also enabled us to identify peaks and troughs in case rates, supporting decisions on when restrictions should be tightened or could be eased.
We recognise that none of this has been easy. The requirement to isolate creates enormous challenges for individuals and their families across the country. A study in March 2021 by the BMJ concluded that offering financial and practical support to individuals who needed to self-isolate would likely improve compliance. We support that view. Since September last year, we have provided councils with £280 million to issue support payments to those who may face financial hardships because of self-isolation. We have also made up to £100 million available between March and September this year for councils to offer practical and emotional support to some of the most vulnerable in our communities, covering over 200,000 people. It is right, though, that we sought to reduce the burden of self-isolation at the earliest opportunity.
The amendments to the self-isolation regulations we are debating balance these factors and provide a significant easing of burden from self-isolation requirements while maintaining vital measures to reduce the spread of the virus. These amendments came into effect on 16 August and allow those who are fully vaccinated to be exempt from self-isolation if they are the close contact of a positive case. Based on the data, we know that the vaccines reduce overall symptoms by between 80% and 90%, hospitalisations by between 90% and 95%, and deaths by around 95%. Therefore, we have adapted our approach to self-isolation to reflect this and ensure we balance the need to slow down the transmission of the disease with the need to get back to normal.
As well as fully vaccinated adults, several other groups have also been exempted from the requirement to self-isolate. The amendment provides an exemption to self-isolation for the close contacts who have taken or are taking part in an MHRA-approved trial for a Covid vaccine. This will ensure that they are not disadvantaged as a result of their personal sacrifice. We recognise also that some groups cannot be fully vaccinated on medical grounds. The amendment therefore includes an exemption for those close contacts who can evidence that they are unable to be vaccinated for medical reasons.
Finally, we have carefully considered the impact on those under the age of 18. There are unqualified harms to children’s educational, emotional and social outcomes as a consequence of self-isolation, as well as of the infection itself. The risk of hospitalisation and intensive care admission in children due to Covid is very low—approximately eight per 100,000 population aged under 18 are admitted to hospital. The incidence of mortality in children as a result of Covid is also extremely low. By balancing these factors, the SI provides an exemption for those close contacts under the age of 18 from self-isolation.
Those who are exempt will be advised to take a PCR test as soon as possible to check whether they have the virus. Though not required to self-isolate, they will
be advised to consider other precautions, such as wearing a face covering in enclosed spaces, as well as limiting contact with others, particularly those who are clinically extremely vulnerable. However, it remains the case that if any of these groups develop symptoms they should self-isolate immediately and take a PCR test. Anyone, whether fully vaccinated or not, who goes on to test positive will remain under a legal duty to self-isolate.
Although I sympathise with the burden and the challenges that self-isolation creates, it will continue to play an indispensable role in containing the virus. The Secretary of State said more on this in his Statement earlier on the winter strategy for tackling the virus. While restrictions are easing, we must all continue to adhere to the self-isolation regulations and the guidance if we are to continue protecting our friends, families and communities. I commend these regulations to the Committee.
