Professor Sophie Harman, Professor of International Politics at Queen Mary has written a piece for The Conversation on vaccine nationalism and how Covid-19 vaccines have become concentrated in rich countries. She writes: "If countries want to solve the problem of vaccine equity they should stop seeing COVAX as the solution, and see it as the charity it is. And they should share vaccine intellectual property and technology without waiting for multilateral institutions to offer permission when the rules already make allowances for this."
