With permission, Mr Speaker, I would like to update the House on the covid-19 pandemic. We are working night and day to understand more about the omicron variant. There is still a lot to learn, but some important data has emerged recently and I would like to update the House on the latest developments.
There are three reasons why the omicron variant is a threat. First, it is far more transmissible than the delta variant. The delta variant was much more transmissible than the alpha variant, and we are confident that omicron is significantly more transmissible than delta. We can see this most starkly when looking at how many days it takes for the number of infections to double for each variant. For delta, this was around seven days, but for omicron, based on the latest data from here and around the world, our latest analysis is that it is between two and a half and three days.
This has made the virus an even more formidable foe. Using S-gene drop-out as a reliable proxy for omicron, the rate of drop-out in England is similar to that observed in South Africa. Although there are only 568 confirmed omicron cases in the UK, we know that the actual number of infections will be significantly higher. The UK Health Security Agency estimates that the number of infections is approximately 20 times higher than the number of confirmed cases, so the current number of infections is probably closer to 10,000. UKHSA also estimates that at the current observed doubling rate of between two and a half and three days, by the end of this month, infections could exceed 1 million.
Secondly, we do not yet have comprehensive data on the severity of this virus, but rising rates of hospitalisation in South Africa show that it certainly has the potential to cause harm. In South Africa, the average age is 13 years lower than in the UK, there is a high level of antibodies from natural infection, and it is currently the middle of summer.
Even if severity is lower or the same as delta, high transmissibility means that the omicron variant can still have a severe impact, with the threat of more hospitalisations and unsustainable pressure on the NHS. That would mean an impact not just on covid treatment, but on the non-covid care that we all rely on, such as emergency care if somebody is sadly involved in a serious accident. When we set out plan B, we said that we would act if the NHS was likely to come under unsustainable pressure and was at risk of not being able to provide the care and treatment that people need. The omicron variant has given us cause for concern.
Thirdly, we have been looking closely at what the omicron variant means for our vaccination programme. New laboratory data that has emerged in the last 24 hours suggests that there is lower immunity against omicron from vaccination when compared with the delta variant, so that two doses of a vaccine is less effective at reducing transmission in the community.
However, early research published today by Pfizer suggests that a third dose of the Pfizer vaccine neutralises the Omicron variant to an extent that is similar to the impact of two doses against the original strain of the virus. It is more important than ever that we get the boosters that are available to all those who are eligible, and that we keep strengthening the defences that we have built. Today, we have opened booster bookings to 7 million more people in England, so people aged 40 and over and those in high-risk groups will be able to get their booster jab from three months after their second dose.
Another defence is new treatments, which have a huge part to play in protecting the most vulnerable from covid 19, especially those who are immunosuppressed, for whom vaccines may be less effective. Today we have announced plans for thousands of people across the UK to be among the first in the world to access life-saving antivirals through a new national study. People who are at highest risk from the virus—for example, those who are immunosuppressed or cancer patients—will also be able to access treatments outside this study from next Thursday if they have a positive PCR test.
We have built some powerful defences. We have put more boosters in arms than any other country in Europe. We have built a huge national infrastructure for testing, and we are leading the world in the deployment of new treatments. Thanks to these defences and our decision to open up in the summer, rather than the winter, we are much better protected than we were this time last year—and we need this protection now more than ever, because although Omicron is becoming more and more prevalent, over the next few days and weeks we will see the Delta and Omicron variants circulating together. Facing these twin threats without these pharmaceutical defences would have been hard enough, but even with them in place we still face a perilous winter, so unfortunately we need to take steps against the threat of this new variant.
When we were moving down our road to recovery, we looked at four tests to see whether we should proceed to the next stage. The tests are: that the vaccine deployment programme is continuing successfully; that the evidence shows that vaccines are sufficiently effective in reducing hospitalisations and deaths in those vaccinated; that infection rates do not risk a surge in hospitalisations that would put unsustainable pressure on the NHS; and that our assessment of the risks is not fundamentally changed by new variants of concern. Unfortunately, the situation is markedly different from the summer, when we were able to open up, so we must take proportionate steps to meet this emerging threat.
These are not measures that any of us wants to take, but these measures give us the best chance of saving lives and protecting our freedom over the next few weeks, and it is precisely because we do not want a lockdown that we are putting these proportionate steps in place now. As we have seen before, if we act early, firmly and decisively, and come down hard on this new Omicron variant, we can avert tougher action later. I know that the news of further measures will be disappointing, of course, for many people, and that every measure comes with a cost. I can assure the House that, in making these decisions, we have taken a wide-ranging view that looks at the impact on not just the NHS, in terms of both covid and non-covid care, but the nation’s education, the economy, life chances and mental health.
I would like to update the House on the measures that we will take to enact plan B. First, we will reintroduce the guidance on working from home. It will be updated to say that only people who cannot work from home should continue to go into their workplace. We know that this has an important part to play in slowing transmission, both at workplaces and on public transport. Secondly, we will introduce mandatory certification, based on vaccines or tests, for nightclubs and large events. This will reduce the number of unvaccinated, infectious people in venues, which could limit overall transmission.
Thirdly, on face coverings, we will be extending the legal requirement from shops and public transport to all indoor public settings, including attractions and recreation, although hospitality will be exempt, and we will be exempting specific activities where it is not possible or practical to wear a face covering—for example, singing and exercise. We will be laying these regulations tomorrow, to come into force the following day.
Fourthly, as omicron spreads in the community, we will also introduce daily tests for contacts instead of isolation so that we keep people safe while minimising the disruption to daily life.
Fifthly, on communications, we will be urging caution in all our communications on covid-19 and will keep urging people to get their booster doses and to follow the little steps that they can to help get the virus under control. All these measures will be reviewed on 5 January, when we will also update the House, and they will all sunset on 26 January.
Finally, we will also be taking further measures to protect and support adult social care, and we will be updating the House on a package of measures later this week.
It is better to stay a step ahead of the virus, rather than reacting to what it brings—to take control of our response now, rather than waiting for what comes next. Waiting a few weeks would make it easier to explain the need for these measures, but by then it might well be too late, so we need to act now and take these balanced and proportionate steps.
We take these steps with a heavy heart, but we do so confident that we are doing everything in our power to keep our nation safe this winter. We have come so far over the course of this year, thanks to the defences that we have built against this deadly virus. Now, as we face this new threat, we must draw on the same spirit that has got us here, strengthening our defences, and think about what we can do to help get this virus under control. I commend this statement to the House.
