Covid vaccine and cancer, snails' trails

Science commentator Siouxsie Wiles joins Kathryn to talk about the latest Covid studies, including the 80 per cent rollout of the Pfizer vaccine to Israeli adults and the safety of the vaccine for cancer patients. She'll also look at new research into the make up of a snail's trail and the new study that calculates how long it would take to escape Auckland in a volcanic eruption. Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
