Show Notes
Mutant strains of SARS-Cov2 have been identified not only in the UK, where it was first identified, but also in at least 30 other countries. And to complicate matters, another alarming variant, with some similar mutations, has arisen in South Africa. Roland Pease talks to Ravi Gupta, a virologist at Cambridge University and Tulio de Oliveira of the University of KwaZulu Natal about these new strains. There’s only so much that can be learned about the virus by looking at the patients it infects. Thanks to techniques developed to study HIV, Ebola, flu and other viruses in the past, researchers have methods for growing key parts of viral structures in the lab and watching closely how they behave in cell cultures. Jeremy Luban of the University of Massachusetts and Alli Greaney at the Fred Hutchinson Cancer Research Center talk to Roland about how they are studying the biology of the mutations to discover how the new strains might respond to vaccines.
