The Graphic Truth: The COVID vaccine race

The global race is on to develop a vaccine against COVID-19. While it usually takes many years to develop and widely distribute vaccines, scientists around the world are now trying to get one ready within an unprecedented time frame: 12-18 months. And while there is some international cooperation in that effort, there's also fierce competition among countries, as everyone wants to develop a vaccine on their home turf first, not only for prestige, but also to get their citizens at the front of the line for the shots when they are available. There are hundreds in development, but to date only eight vaccines have progressed to Phase III of the clinical trial process, meaning they are being tested on thousands of people and the results are compared with those who receive a placebo drug. Phase III is the final stage before approval. Who's gotten there so far?
