Yes, it is very much part of the plan; it is happening right now. On mutations and the link to the vaccine, as with flu, where mutations mean we have to change the vaccine each year, any vaccine might have to be updated in the future, but that is not our understanding of the situation now. Of course that is being double-checked and tested, both with the scientists at Porton Down and, as we roll out the vaccine in areas where there is a high degree of the new variant, and by the pharmacological surveillance of those who have been vaccinated, which will allow us to see for real the impact of the vaccine on the new variant. The goal, as my right hon. Friend the Prime Minister said, is that by the middle of next month we plan to have offered the first dose to everyone in the top four priority groups, and they currently account for four out of five covid fatalities. I am not sure that this point has fully been addressed, but the strong correlation between age and fatality from covid means we will be able to vaccinate those who account for four out of every five fatalities within the top four cohorts. It does then take two to three weeks from the first dose to reach immunity, but the vaccine is therefore the way out of this pandemic and the way to a better year ahead.
