Co-creation – the joint production of innovation between combinations of industry, research, government and civil society – was widely used to respond to the challenges raised by the COVID-19 pandemic. This paper describes 30 COVID-19 co-creation initiatives from 21 countries and three international cases. The template focuses on initiatives’ core characteristics, including information on key co-creation partners and their contributions, key outcomes, and the initiatives’ size. The comparative evidence gathered through interviews with case study initiative leaders also describes what co-creation instruments were used, how networks leading to the collaboration were built, what type of cross-disciplinary co-operation took place, and what role governments played in the process and the procedures adopted to deal with the COVID-19 'exceptionality', including the urgency of producing implementable solutions. The information gathered provides a basis for analyses on co-creation initiatives during COVID-19 and for drawing potential policy implications.
