Thus far, young people have had limited effects from COVID-19. They have clearly been transmitters of it, however, and they can transmit it to people who are much more vulnerable. Therein lies a substantial part of the problem. The significance of the booster vaccination — the fact that our immunity can go from somewhere around 40% to well over 90% — was mentioned. I am glad that Northern Ireland is now beginning to pick up on getting the booster programme rolled out. It seemed to be a bit slow: 10 days ago, 300,000 people who were eligible for it still had not received it. Of course, many people are coming under the eligibility criteria now. We need to push ahead and get the booster vaccination to as many people as possible before Christmas and particularly to people with vulnerabilities. I encourage people to do that.
