I am extremely pleased to hear the update from my noble friend, and I thank all those in Lincoln who were contributing to his effective vaccination and his second appointment, which is very reassuring. I reassure him that, on the Israeli numbers, Sir Patrick Vallance, the Chief Scientific Adviser, has been very clear—he was on the media round this morning. The Israelis looked at a very specific time period—14 days—and a very specific age group. This is very different to the analysis done by the JCVI and the MHRA, which looked at all age groups over a much broader period. The efficacy of immunity from days 10 to 21 is thought to be 89%. That is a very considerable and impactful effect, and I have spoken to the noble Baroness, Lady Boothroyd, to reassure her on that matter.
