To end the COVID-19 pandemic, we must end it everywhere. Fair and equitable access to vaccines is essential. The World Bank’s rapid mobilization of vaccine financing aims to support affordable and equitable vaccine acquisition and deployment, and to signal to potential suppliers that Bank financing is available to its clients. Such a commitment provides an incentive to the vaccine manufacturers to supply developing economies at affordable prices. All eligible Bank client countries (IBRD/IDA) can access the vaccine financing within their current lending envelopes for IDA countries and exposure limits for IBRD. The World Bank Group is working in global solidarity with COVAX, WHO, UNICEF and other partners at global and country levels to support IDA and IBRD countries. This financing can be used by countries to make payments to COVAX, including the purchase of additional doses beyond the COVAX-provided 20% as countries aim for higher levels of coverage.
