Biontech and Pfizer, Moderna, Astra-Zeneca - the leading western manufacturers of vaccines against Covid-19 have been the focus of global interest for months.
In contrast, the Chinese company Sinovac has received surprisingly little attention so far.
His vaccine is said to have been vaccinated hundreds of thousands of times by the Chinese - if you believe the information from Sinovac.
This cannot be verified. The authoritarian surveillance state hardly lets journalists into the country. An application for approval of the vaccine has not yet been submitted to the European approval authority EMA. An international run has long since broken out on the Chinese vaccine.
