Gavi, the Vaccine Alliance is a partnership between public and private organizations that has helped vaccinate half the world’s children against some of the world’s deadliest diseases. Since its inception in 2000, Gavi has helped to immunize a whole generation and prevented more than 14 million deaths, helping to halve child mortality in 73 developing countries. Gavi is also securing vaccines for COVAX, the only global initiative that is working with governments and manufacturers to ensure that COVID-19 vaccines are available worldwide to both higher-income and lower-income countries.
