John E. Lange, Director of the Global Health Program of the Bill & Melinda Gates Foundation, and former U.S. Ambassador to Botswana, discusses virus sample sharing and access to vaccines among different nations. He notes that pandemic threats are not just health issues, but rather a burden on every sector of society. He asserts that community mitigation measures - that governments will need to employ in the first months of a pandemic - are an essential element in any pandemic response.
