BBC global health correspondent Naomi Grimley joins Claudia Hammond for a round-up of the latest developments in Covid vaccines and their rollouts – including the World Health Organisation’s Director General who has admonished richer countries and pharma companies for undermining the chances of access to vaccines for all countries. Plus a controversial vaccine rollout in India and the Iranian leader wants to ban US and UK vaccines. Claudia’s guest of the week is family doctor Ann Robinson who has perspectives on some of the latest Covid treatment news. Early results suggests a place for two monoclonal antibodies in treating patients who are sick enough to be in intensive care, although the drugs are expensive. And there are some encouraging results from a small trial in Argentina of convalescent plasma therapy in older mildly ill patients. The pandemic has disrupted the training of the next generation of health professionals. From Chile, Jane Chambers reports on how a leading dental college in Santiago is innovating to keep the practical tuition of its students up to standard. Ann Robinson tells Claudia about new research measuring the role of air pollution in miscarriages and stillbirths in India, Pakistan and Bangladesh. Should only doctors do surgery? Claudia talks to Sierra Leonian surgeon Thomas Ashley and Jenny Lofgren of the Karolinska about training more junior health care workers to perform relatively simple surgical procedures such as hernia repair, in the hope of addressing the enormous unmet need for this operation across sub-Saharan Africa.
