The United Nations International Children's Emergency Fund (UNICEF) launched the Covid-19 Vaccine Market Dashboard to provide a comprehensive overview of global vaccine supply and distribution. This dashboard is a critical tool for tracking the progress of the COVAX facility, which aims to ensure equitable access to Covid-19 vaccines, particularly in low- and middle-income countries. The dashboard provides detailed information on vaccine production, procurement, pricing, and delivery, helping governments and stakeholders monitor the status of global vaccination efforts during the pandemic. UNICEF plays a pivotal role in global vaccination campaigns, partnering with the World Health Organization (WHO) and GAVI, the Vaccine Alliance.
