Jaclyn Winter and Shiladitya DasSarma will discuss how they harness the unique biology of extremophiles for the discovery and development of new therapeutics.
The move, which is not supported by the pharmaceutical industry, would allow other countries to design and manufacture COVID-19 vaccines without fear of litigation.
