Joint Evaluation of COVAX (2020–2023) Ensuring equitable supply and delivery of vaccines duringCOVID-19: what worked, what didn’t and what’s next? EVALUATION FINDINGS COVAX delivered nearly2 billiondosesof COVID-19 vaccines to What’s COVAX? Global coordinationwasagile, but regional structureswere underused and rolesremained unclear, limitingresponsiveness and countryownership. Launched during the COVID-19 pandemic, COVAX aimed to ensure fair access toCOVID-19 vaccines globally.Co-led by CEPI, Gavi, WHO, and UNICEF, it combined globalprocurement with country-level delivery support. COVAX was the first global mechanism ofits kind, designed and deployed at unprecedented scale during the COVID-19 pandemic. of all doses in low-income countries,demonstrating that multilateralmechanisms can deliver equitablyin a crisis. 147countries How do you deliverCOVID-19vaccines fairly at speed during a global pandemic? COVAX helped ensureequitybetween coun-tries, but limited focuson intra-country equitymade it harder to reachthe most vulnerable. Delivery financingwas initially rigidand insufficient andonly became moreflexible in 2022. Anend-to-end modelemerged over time, butearly gaps in strategy,planning, and coordinationreduced COVAX’s ability toact swiftly and equitably. This independent joint evaluation, commissioned by Gavi with COVAX partners,examines the full scope of the COVAX effort: Procurement and allocationthrough the COVAX Facility and AdvanceMarket Commitment. Country-level deliveryvia the COVAX Delivery Pillar. RECOMMENDATIONS The evaluation captures what enabled success, where systems faced limitations, and what it will take to do better next time.The evaluation employed a non-experimental, theory-based evaluation using a systems lens to assess the implementation andadaptation of the COVAX Facility and AMC and Delivery Pillar Efforts in achieving their intended results. Key lessons from 147 countries, including deep dives in seven, offer a roadmap for future pandemic preparedness and vaccine equity. GOVERNANCE SUSTAINABILITY FINANCING EQUITY The evaluation callsfor clearer objectives,more inclusiveleadership, andstronger regionalengagement. Transition and long-termsystems strengtheningrequire early planning,grounded in clearly definedroles and comparativeadvantages across levelsand partners. Mechanisms shouldpromote both inter-and intra-countryequity through earlyplanning and localengagement. Delivery supportshould be adequatelyfunded, timely, flexible,and integrated fromthe start. Case studies and deep divefrom seven countries– Cameroon,Côte d’Ivoire, Guyana, Indonesia, Somalia, Uzbekistan, Zambia –provide grounded insights. For example, strong national–partner coordinationin Guyana enabled outreach to remote regions; inSomalia, pivoting to single-dose vaccines improveduptake; and in Uzbekistan, COVID-19 vaccines wereintegrated into routine immunization. Why does it matter?The next global health emergency will demand faster, moreinclusive, and better coordinated responses. This evaluation provides evidence tostrengthen future partnership mechanisms—from governance to delivery, fromfinancing to equity.
