The Global Vaccine Summit, hosted by the UK, raised 8.8 billion U.S. dollars to support vaccination and save more lives. Leaders from over 30 countries and heads of international organizations attended the summit. The summit aims to raise funds for the Global Alliance for Vaccines and Immunization (GAVI) to ensure vaccine accessibility worldwide. The funds will immunize further 300 million children in the world's poorest countries by 2025. Once a safe and effective COVID-19 vaccine is developed, GAVI will have a role in its delivery around the world.
