With more than 200 potential COVID-19 vaccines currently at various stages of development across the world, it can be difficult to know which stage each one is at.

The Agenda with Stephen Cole talks to Beate Kampmann, director of the vaccine center at the London School of Hygiene and Tropical Medicine, who has led the development of an online tracker that follows the progress of all potential COVID-19 vaccines.

Kampmann has concerns over the speed at which the vaccines are being developed but she is confident the tracker will be invaluable in the race to defeat this virus.
