Mr. Evans, have you done any modelling around the progress towards herd immunity, based on the government's vaccine projections? People have started to receive their vaccines, and perhaps everyone will be vaccinated by September 2021, but that still does not mean that we will have reached herd immunity. Has the task force done any modelling around herd immunity? When do you think we will reach herd immunity?
With so few people vaccinated to date, is it not essential to keep the health measures in place for a long time, or even strengthen them?
