Henrietta Lacks died in 1951 from a virulent cervical cancer. A sample of those cancer cells was taken at the time, and the way they behave has changed medical science forever, contributing to everything from the polio vaccine to drugs for Parkinson’s and Alzheimer’s disease. As the WHO give a posthumous award, Claudia discusses how the Henrietta Lacks legacy raises issues of global health equity.

Plus with a Malaria Vaccine given a historic green light by the WHO to protect children in Africa, what are the distribution difficulties in countries which carry the greatest burden of disease?

And what’s behind the low rate of Covid-19 vaccinations in Taiwan? We hear from one resident about why she’s chosen to have a home-grown Medigen vaccine which hasn’t yet completed all its clinical trials – and another who wants to wait for an alternative. Scientists say that trials about to start in Paraguay should show whether it stimulates enough immunity to protect people in the way the AstraZeneca vaccine does.
