This is a podcast series with some of the people I spoke with for a story about the creative grit scientists in The Global South apply in the fight against COVID-19. They collaborate, they network, they get creative to get what they need: supplies and strength for their research. In the haste to clinical trials for the COVID-19 vaccines some people were missed who need special attention. Thomas Egwang talks about why he and his colleagues submitted a letter to Nature Immunology about this and how research on this "quarter of humanity" continues.
