In mid-February, Steve Morrison of the CSIS Global Health Policy Center attended the Munich Security Conference. There, he moderated a roundtable on health in disordered settings, a town hall on COVID-19, and a dinner with Norwegian Prime Minister Erna Solberg. He also spoke with a variety of policymakers, donors, and agency heads that are leading the response to the coronavirus epidemic. In this fourth episode, Steve speaks with Paul Stoffels, Vice Chairman of the Executive Committee and Chief Scientific Officer at Johnson & Johnson. They discuss the unknowns surrounding the COVID-19 virus, the Chinese response, and the role J&J is playing in developing a vaccine.
