Sinovac Biotech Ltd.

A Chinese biopharmaceutical company that researches, makes, and sells vaccines against human infectious diseases, including its well-known COVID-19 shot CoronaVac as well as vaccines for hepatitis A and B, seasonal flu, and avian flu. Founded in 1999 by Yin Weidong, who started by developing China's first proprietary inactivated hepatitis A vaccine, Healive. Its name is a portmanteau of "Sino" (China) and "vac" (vaccine), neatly summing up its whole business in one word.
