The covid-19 pandemic has caused upheaval across the world, forcing Governments everywhere to wrestle with how to keep their citizens safe while protecting the liberties that we all hold dear. We have learned a lot from our experience and the experience of others, and of course we are still learning. But we can take huge pride that thanks to the defences that we have built, so much of this year has been a year of recovery. We have enjoyed greater freedom than at any time during the pandemic so far. Thanks to the rapid progress of our vaccination programme, our investment in treatments and our decision to open up during the warmer summer months, we are in a far stronger position than we were last winter.
But even as I stood at this Dispatch Box back in July to announce the major milestone of taking step 4 in our road map, I said that
“we know that the greatest risk to the progress we have made is the possibility of another new variant, especially one that can escape immunity and puncture the protective wall of our vaccination programme”.—[Official Report, 12 July 2021; Vol. 699, c. 22.]
We have always known that variants have the potential to knock us off our course, and we have built the capacity to identify and respond to those that pose a threat.
The vast majority of new variants present no risk whatsoever. Since the summer, there have been hundreds of new variants, but only one of them—omicron—has been designated a variant of concern. For example, just
last month, I updated the House from this Dispatch Box on AY.4.2, a new form of the delta variant, which preliminary analysis showed at that time might be more infectious. I said then that we would keep it under review, and that is what we did—and we took no action.
But omicron is a grave threat. We acted early to slow its spread, strengthening our testing regime and placing 11 countries on the travel red list, but despite those swift steps, the data over the past few days has shown more cause for concern. I would like to reinforce to the House today—to all hon. Members—why omicron represents such a risk to the progress that we have all made so far together.
