The private sector is ramping up fast COVID-19 vaccine production, thereby narrowing the gap between vaccine supply and demand. The purpose of this note is to report the latest estimates of how much of the vaccine shortage will be eliminated this year, given what is known today about existing vaccine production capacity, announced capacity expansion this year, and sobering lessons learned from attempts to boost production during the first five months of this year. The projections reported here do not include any extra production that might result from the adoption of a TRIPS waiver at the World Trade Organization.
