Science in Action looks at some of the latest research on the response of our immune system to infection by the coronavirus. Researchers at Kings College London find that protective antibodies appear to fade away after about three months following infection whereas a team at the Karolinska Institute has discovered that although antibodies may decline, other important players called T cells in our defences do not. Dr’s Katie Doores and Marcus Buggert talk about the implications of these discoveries for the quest for a vaccine against the coronavirus.

Roland Pease also talks to Dr Barney Graham of the National Institute of Allergy and Infectious Diseases in the United States about the results from the Phase 1 trial of a novel type of vaccine against the virus. NIAID have partnered with biotech company Moderna to produce the first mRNA vaccine in the Institute’s pandemic preparedness program.

Biologist Dr Sonja Wild tells Roland about the remarkable fishing strategy devised by dolphins in Shark Bay, Australia. They chase fish into the empty shell of giant sea snails, then take the shells to the surface and tip the fish into their mouths. Dr Wild’s 7 years of research has revealed how the dolphins have learned to do this.
