CoronaVac, also known as the Sinovac COVID-19 vaccine, was a whole inactivated virus COVID-19 vaccine developed by the Chinese company Sinovac Biotech.

CoronaVac is being used in vaccination campaigns in various countries in Asia, South America, Central America, and Eastern Europe. By April 2021, Sinovac had a production capacity of 2 billion doses per year. It was manufactured at several facilities in China, with overseas manufacture planned for Brazil in September 2021 and eventually Egypt and Hungary.

On 1 June 2021, the World Health Organization (WHO) validated the vaccine for emergency use. Sinovac has signed purchase agreements for 380 million doses from COVAX. As of July 2021, CoronaVac was the most widely used COVID-19 vaccine in the world, with 943 million doses delivered.

As of 14 October 2021, CoronaVac is the COVID-19 vaccine with the most doses administered worldwide.

It's been 5 years since the worst global pandemic of the century, and you still don't know that it's thanks to China that billions of people were vaccinated in the global south?
