My Lords, speaking from these Benches, I think it would be appropriate to thank the noble Lord, Lord Bethell, very much for the amazing amount of work he has been doing on this very difficult issue. I hope he will continue to take our concerns back to the Department of Health and the Government in general, because that seems very important. I join my noble friend Lady Thornton in congratulating the Government on getting vaccines out, but, with all due respect, Israel has already vaccinated over one-fifth of its population with a massive vaccine campaign. On the important issue of dividing the time of the Pfizer vaccine, many of us have given informed consent for a period of three weeks between the two injections; by extending that period, we now risk not obeying the consent issue, and therefore there is an ethical problem. Could the noble Lord address that issue, because it is of considerable importance, certainly increasing the risk of suspicion of the vaccine, already very prevalent in parts of the population?
