With the failure of the PrEPVacc trial in Southern and Eastern Africa, HIV researchers are concerned that an HIV vaccine will not be developed before 2030 at the earliest. Claudia Hammond is joined by Matt Fox, Professor of Global Health Epidemiology at Boston University, to discuss the latest news about HIV vaccines, funding and treatment from around the world.

We also hear about Super 5, a home-grown nutritional supplement being made by rural women in Rajasthan, in India, to address the problem of child undernutrition and malnutrition.

Claudia also speaks to Dr Ra拧ads Misirovs to talk about sneezing. In a rare case, a patient of Dr Misirovs in Scotland tore a hole in their windpipe by stifling a sneeze. We learn more about why we sneeze as well as how to prevent injury when doing so.

Claudia and Matt also discuss how deaths from work-related illnesses are increasing, and concerns over the huge increase in calls to poison centres in the US because of accidental overdoses of injected weight-loss drugs.
