What is COVAX in the context of COVID-19?
COVAX is the vaccines pillar of the Access to COVID-19 Tools (ACT) Accelerator. The ACT Accelerator is a ground-breaking global collaboration to accelerate the development, production, and equitable access to COVID-19 tests, treatments, and vaccines.
What is the Covax initiative for the development of COVID-19 vaccine?
COVAX aims to accelerate the development and manufacturing of COVID-19 vaccines, and guarantee fair and equitable access for every country. COVAX is co-led by the Coalition for Epidemic Preparedness Innovations (CEPI), Gavi and WHO, with UNICEF as a key delivery partner and PAHO as the procurement agent in the Americas.
