Bloomberg has created a series of visualizations tracking the progress of the world’s nine most promising COVID-19 vaccines. One visualization tracks each vaccine’s stage of development, showing which ones are still in trial, which ones are awaiting approval, and which ones are approved for the public. Currently, five vaccines have been approved for the public. Another visualization shows which countries have struck deals for access to these vaccines. It shows that AstraZeneca’s vaccine is the early leader, with pre-purchase agreements to cover 1.46 billion people—more than twice as many as any other candidate.
