i'm geeta guru—murthy.alf a century, the debate on democracy focused on growth as more and more countriesjoined the league of democratic nations. but since the turn of the century, there has been what the scholar larry diamond has called "a democratic recession". some believe the movement towards democracy right around the world has gone into reverse. today, we look at one example, hong kong, which one might have thought to have been pretty fragile all along, and another, the united states, which is among, of course, the most established democracies in the world. with me to discuss whether trump and his supporters will go quietly as we look forward to the inauguration ofjoe biden on 20th january are bloomberg's stephanie baker, political commentator steve richards and here in the studio, our diplomatic correspondent james landale. thanks to all of you. well, we start with an extraordinary week in american politics. forfour years, the trump presidency has appeared to be waging a contest with the american con

earlier my colleague geeta guru—murthy discussed the issue with adam finn, professor of paediatrics atnd leora cruddas, chief executive of the confederation of school trusts. as a paediatrician, i'm extremely concerned that we try and keep schools resilient and preferably open them as soon as possible. one of the main ways of doing that it will be to protect the teaching staff. the age profile of severe covid is very... age is a very strong predictor of severity. in that excellent and very disturbing report from fergus walsh just now, we saw that of course it isn't just old people, but also, to some extent, adults of a younger age that can be affected. i think in the next phase of the roll—out, once the most vulnerable groups have been immunised, hopefully, as soon as possible, then teachers, on a personal level, i would certainly endorse the idea that teachers should be prioritised. that decision will be debated over the next month byjcvi and we expect to have a phase two plan by next february. but you think that should happen ahead of people, who are, for example, over 50? that's not

now on bbc news — another chance to see your question's answered a little earlier with geeta guru—murthyions in us your questions on the coronavirus vaccine and lockdown rules across the uk. with me now to answer some of those questions i'm joined by doctor naomi forrester—soto, a virologist at keele university and by professor keith neal, emeritus professor in infectious diseases at the university of nottingham. thank you both very much forjoining us today. can i start with you, naomi. and a question from david williams who says, on vaccines, does the second dose administered have to be the same type as the first? that's a really good question. against the same spike protein and there is evidence from the literature that what we call giving one dose of vaccine and a second dose of a second vaccine, has sometimes been beneficial. so although the vaccines were tested in clinical trials with the same repeated dose, there are now trials going on, i think, orjust about to start, to test whether or not this heterologous boosting would actually be beneficial. so in an ideal situation, i would
