My hon. Friend may well have heard the statement by the Secretary of State for Health and Social Care, after which he answered a large number of questions about the vaccine. As he said, we will be rolling out the vaccine as rapidly as possible, we are poised and ready to start rolling out that particular vaccine as of next week, and it is all about getting the supply of the vaccine in to enable us to do that.
There is light at the end of the tunnel, but we are not there yet. We are here today to debate regulations that increased the restrictions on parts of the country before Christmas, but we also heard the Health Secretary’s statement earlier and know the seriousness of the situation we face despite those greater restrictions. We know that we have just had the highest number of new cases in one day—over 53,000—and in many parts of the country, our hospitals are stretched to the limit. We know we are facing a new variant of covid that is more infectious and spreading rapidly in many parts of the country, so I am in no doubt that we were right to introduce further restrictions when we did.
Before going into the details of the regulations, I will give a brief overview of the measures we are debating. On 2 December, a revised tiering system was introduced following approval of the all-tiers regulations in both Houses. Those have been amended four times. On 14 and 16 December, the all-tiers regulations were amended to move some local authority areas between tiers. Those changes came into force on 16 and 19 December respectively. On 20 December, the all-tiers regulations were amended to introduce a further level of restrictions—tier 4—and to move some local authority areas into that tier and to exclude tier 4 from the Christmas easements. Finally, on 24 December, the all-tiers regulations were amended to move some local authority areas into higher tiers, and some amendments were made to the measures in tier 4.
In addition to those four amendments to the all-tiers regulations, we are debating the Health Protection (Coronavirus, Restrictions) (Self-Isolation and Linked Households) (England) Regulations 2020, which reduce the self-isolation period for household and non-household contacts from 14 days to 10, based on evidence showing that the likelihood of being infectious as a contact after 10 days is low. That decision was made following advice from UK chief medical officers. To bring English policy in line with other nations in the UK, we now count the start date of this period from the day after exposure, onset of symptoms or a test. Those with covid-19 should continue to self-isolate for 10 days, as per Government guidelines. We have brought the wait time for those switching support or childcare bubbles down to 10 days, in line with those changes.
I know that some hon. Members have previously raised concerns about parliamentary scrutiny, and some may be disappointed that those amendments were made in advance of this debate. However, I am sure hon. Members will also appreciate that this virus does not wait for parliamentary procedure. The situation we faced in the run-up to Christmas, as we identified that the cause of the rapid rise in infections was the new variant, meant that we had to act, and act fast.
