Sinovac and Sinopharm - what do we know about the Chinese vaccines?

China has been developing Covid-19 vaccines since the very beginning of the pandemic.

It was the first country in the world to give a vaccine to some of its population in summer 2020.

It currently has 16 different vaccines at various stages of development, but the current front-runners are from Sinovac and Sinopharm.

China has agreed deals with more than 20 countries and has plans to export vaccines all over the world.
