Inside the Chinese companies vying to produce the world's first coronavirus vaccine

For all its innovative prowess, China has generally lagged other countries in developing vaccines. But that appears to be changing with the race for a coronavirus vaccine, with Chinese companies potentially even at the forefront. As often with China, the question is: who are we dealing with? Who are the main vaccine developers? How far are they in developing a vaccine? What is their approach? What is the connection to the Chinese state? And what is the outlook if China comes up with the vaccine first? Of the 32 vaccines that are in human trials around the world, a larger number are from Chinese companies than might have been expected. The three leading players are Sinovac, CanSino Biologics and Sinopharm.
