However, vaccine developers' practices were not monolithic, but rather, took diverse approaches to supplying different countries, with important implications for global access. RESULTS: Using data on R&D investments, regulatory approvals, manufacturing and purchase agreements, and vaccine deliveries, we identified six distinct innovation models that apply across the 14 COVID-19 vaccines with more international presence from 2020–2022. “Western Early Arrivers” Pfizer/BioNTech and Moderna supplied the largest volumes quickly and prioritized high-income countries (HICs) from registration to vaccine delivery. “Western Latecomers” Janssen and Novavax supplied intermediate volumes later, also prioritizing HICs but with a greater proportion to L&MICs. “Major Chinese Developers” Sinopharm and Sinovac supplied intermediate volumes early, primarily to middle-income countries (MICs). “Russian Developer” Gamaleya completed development early but ultimately supplied small volumes, primarily to middle-income countries (MICs). “Cosmopolitan Developer” Oxford/AstraZeneca supplied large volumes early to HICs and MICs at the lowest prices. Finally, “Small MIC Developers” CanSino, Bharat Biotech, Medigen, Finlay Institute and the Center for Genetic Engineering and Biotechnology (CGEB), exported relatively small volumes to a few MICs. Low-income countries (LICs) were not targeted by any developer, and received far fewer doses, later, than any other income group. Almost all developers received public funding and other forms of support, but we found little evidence that such support was leveraged to expand global access. CONCLUSIONS: Each of the six innovation models has different implications for which countries get access to which vaccines, how quickly, and at which prices. Each offers different strengths and weaknesses for achieving equitable access. Our findings also suggest that Western firms had the greatest capacity to develop and deliver vaccines quickly during the pandemic, but such capacity is rapidly becoming more globally distributed with MICs playing a significant role, especially in supplying other MICs. Given the critical role of public support in enabling pandemic vaccine development and supply, governments have both the capacity and responsibility to craft international rules that will make responses to future pandemics more equitable and effective. 000318763 542__ $$fOpen Access - Creative Commons Attribution 4.0 International License$$uhttp://creativecommons.org/licenses/by/4.0/ 000318763 580__ $$aIn: Globalization and Health. - Volume 20(2024), article number 25, pages 1-24 000318763 6531_ $$aGlobal Health$$0319129 000318763 700__ $$aRuiz, Adrián Alonso 000318763 700__ $$aBezruki, Anna 000318763 700__ $$aShinabargar, Erika 000318763 700__ $$aLarge, Kaitlin Elizabeth 000318763 700__ $$aVieira, Marcela 000318763 700__ $$aSlovenski, Iulia 000318763 700__ $$aLiu, Yiqi 000318763 700__ $$aAgarwal, Surabhi 000318763 700__ $$aBecker, Anna 000318763 700__ $$aMoon, Suerie 000318763 8564_ $$96f9b9bb5-4448-4d04-8b3b-0fb6120f5ddb$$s3059855$$uhttps://repository.graduateinstitute.ch/record/318763/files/GHC_s12992-024-01017-z.pdf 000318763 901__ $$uInternational Relations - Political Sciences Department$$0319288 000318763 901__ $$uGlobal Health Centre$$0319295 000318763 901__ $$uInterdisciplinary Programmes$$0319283 000318763 901__ $$uGlobal Governance Centre$$0319297 000318763 909CO $$ooai:repository.graduateinstitute.ch:318763$$pGLOBAL_SET$$pIHEID:Explore 000318763 981__ $$aoverwrite
