Number of COVID-19 vaccine doses produced in China 2021-2022
By the end of January 2022, almost five billion COVID-19 vaccine doses were manufactured in China, making the country by far the largest producer of COVID-19 vaccines globally. While most vaccines were for domestic use, a considerable portion of vaccines was exported via sales and donations, mainly to lower or middle-income countries. In comparison to western mRNA vaccines such as Comirnaty or Spikevax, inactivated COVID-19 vaccines developed by Sinovac and Sinopharm have a lower efficacy rate.
