This is the remarkable story of how the UK’s Recovery Trial saved the lives of hundreds of thousands of Covid patients. It was set up in nine days, after a conversation on the number 18 bus. Within 100 days it had found the first life-saving drug. This trial has united thousands of doctors, the NHS and 40,000 patients, at the scariest moments of their lives, changing the pandemic, and possibly medicine, forever. We speak to Oxford professors Martin Landray and Peter Horby who devised the Recovery Trial, and to some of the doctors and patients who helped make it happen.PRESENTER: James Gallagher PRODUCERS: Geraldine Fitzgerald & Beth Eastwood

I was floored for three days with side-effects after having my first Covid jab and many of you have been in touch about your side-effects too. Why do some of us feel awful after the vaccine, while others barely notice anything? What does this say about our immune systems and how protected we will be against covid? We put your questions to Eleanor Riley, a professor of immunology and infectious disease at Edinburgh University. Our resident GP Margaret McCartney has been taking a look at the reports of blood clots after vaccination, and we speak to Victoria Male, a lecturer in reproductive immunology at Imperial College London, about the rules for vaccination in pregnant women.PRESENTER: James Gallagher PRODUCERS: Beth Eastwood & Geraldine Fitzgerald

I have become hooked on playing online chess during this lockdown and after watching the Queen’s Gambit. So we’ll find out if it is actually doing my brain any good and whether it and similar games can ward off dementia. Margaret McCartney takes us on a fascinating tour through the history of deliberately infecting people with diseases, as the first “challenge trials” with coronavirus are about to start.

What has the pandemic done to our sex lives? We’ll hear if there’s been a baby boom with Dr Margaret McCartney and Dr Rebecca Thomson-Glover has the lowdown on sexually transmitted infections.

We speak to Charmayne whose surgery has been held up by the pandemic and Nick Arresti from the British Orthopaedic Association to see how such waiting lists can be tackled.

Most people recover rapidly after catching coronavirus. But I chat to three people who were infected almost a year ago and are still feeling the impact, both on their bodies and their minds. Doctors are having to rapidly grapple with how to treat patients with long Covid. We speak to one of them, Dr Manoj Sivan, the Research Lead for the Long Covid Service in Leeds, who warns that long Covid could be a “second pandemic”. We also have GP Dr Navjoyt Ladher answering your questions on the Covid vaccines.PRESENTER: James Gallagher PRODUCER: Beth Eastwood

A fever, cough or loss of smell and taste are criteria for a Covid-19 test, but what if you have different symptoms? James Gallagher discusses whether more symptoms should be added to the UK government's list with resident GP, Margaret McCartney and Dr Thomas Struyf of KU Leuven.Cardiologist Dr Rohin Francis explains what symptoms he sees when patients with coronavirus arrive in hospital. One of the most common symptoms of Covid-19 is the loss of the sense of smell. It returns after a few weeks in most people but a significant minority still can’t smell anything many months later. James Gallagher talks to Prof Carl Philpott of Norwich Medical School who has led an international panel of nose doctors, assessing the evidence for the best therapies to restore the olfactory sense to people who have lost it following respiratory infections. So-called smell training comes out top as the most evidence-based approach. Carl explains how it works and we hear from two people who are trying to regain their sense of smell.And Dr Carly Welch from the British Geriatric Society says that delirium has emerged as another symptom of Covid-19, particularly in the elderly.
