The COVID-19 pandemic is causing unprecedented human and economic costs in all countries and societies across the world. Collectively, the availability of safe and effective vaccines against the virus, specialized diagnostics technologies and therapeutics, as well as adherence to public health and social measures, and preventing new zoonotic introductions, are instrumental in saving further lives. The vaccine pillar of the Access to COVID-19 Tools Accelerator (COVAX) Facility aims to accelerate equitable access to appropriate, safe and efficacious vaccines for all countries. As of January 2021, over 200 novel coronavirus vaccine candidates are under development, of which 64 are in clinical trials. The London School of Hygiene & Tropical Medicine has developed an interactive tool1 that tracks the progress of the candidate vaccines in real time. It is recommended to access it regularly to verify the status of the vaccines’ development progress, profiles and potential controlled temperature chain (CTC).
