Andrew Marr talks to two of the leading scientists who were at the forefront of research into fighting the spread of Covid-19. Professor Teresa Lambe was one of the Principal Investigators overseeing the Oxford/ AstraZeneca vaccine programme. She co-designed the vaccine and led the pre-clinical studies, as well overseeing the impact on immunity. She will be taking part in this year’s Royal Institution Christmas Lectures (to be aired on BBC 4 at 8pm on 28th, 29th and 30th December), alongside Professor Catherine Noakes. As an engineer Noakes is one of a tiny number of specialists worldwide who study ventilation and the spread of airborne diseases. From the beginning of the pandemic she has been instrumental in providing advice on how the virus transmits and the best strategies to control its spread.

Covid-19 is a respiratory disease and one of the books on this year’s Royal Society prize shortlist is at the centre of revived interest in how we breathe. James Nestor argues, in his book Breath, that humans have lost the ability to breathe correctly, with damaging consequences that reach beyond snoring, asthma and allergies. Drawing on ancient wisdom and the latest scientific studies Nestor highlights the huge benefits from breathing through your nose, rather than your mouth.
