Sinovac Biotech Ltd. (Chinese: 科兴控股生物技术有限公司, Nasdaq: SVA) is a Chinese biopharmaceutical company that focuses on the research, development, manufacture, and commercialization of vaccines that protect against human infectious diseases. The company is based in Haidian District, Beijing in China.[3] The company is listed on the NASDAQ but the exchange halted Sinovac's trading in February 2019 due to a proxy fight.[4][5] The company has faced bribery probes in China.[4]

Vaccines

Sinovac's commercialized vaccines include CoronaVac (COVID-19 vaccine), Inlive (Enterovirus 71 vaccine), Anflu (influenza vaccine), Healive (hepatitis A vaccine), varicella vaccine and mumps vaccine.[6]

COVID-19 vaccine development

Main article: CoronaVac

CoronaVac is an inactivated virus COVID-19 vaccine developed by Sinovac.[7] It has been in Phase III clinical trials in Brazil,[8] Chile,[9] Indonesia,[10] Philippines,[11] and Turkey.[12]

It relies on traditional technology similar to BBIBP-CorV and BBV152, otherwise known as inactivated-virus COVID-19 vaccines in Phase III trials.[13] CoronaVac does not need to be frozen, and both the vaccine and raw material for formulating the new doses could be transported and refrigerated at 2–8 °C (36–46 °F), temperatures at which flu vaccines are kept.[14]

A real-world study of ten millions of Chileans who received CoronaVac found it 66% effective against symptomatic COVID-19, 88% against hospitalization, 90% against ICU admissions, and 86% against deaths.[15] In Brazil, after 75% of the population in Serrana, São Paulo received CoronaVac, preliminary results show deaths fell by 95%, hospitalizations by 86%, and symptomatic cases by 80%.[16][17] In Indonesia, real world data from 128,290 healthcare workers showed 94% protection against symptomatic infection by the vaccine, beating results in clinical trials.[18]

Phase III results from Turkey published in The Lancet showed an efficacy of 84% based on 10,218 participants in the trials.[19][20] Phase III results from Brazil previously showed 50.7% efficacy at preventing symptomatic infections and 83.7% effective in preventing mild cases needing treatment. Efficacy against symptomatic infections increased to 62.3% with an interval of 21 days or more between the doses.[21]

CoronaVac is being used in vaccination campaigns in various countries in Asia,[22][23][24] South America,[25][26][27] North America,[28][29][30] and Europe.[31][32][33] By April 2021, Sinovac had a production capacity of two billion doses a year[34] and had delivered 600 million total doses.[35] It is currently being manufactured at several facilities in China,[34] Brazil,[36] and Egypt.[37] On 1 June 2021, the World Health Organization (WHO) validated the vaccine for emergency use.[38][39][40] Sinovac has signed purchase agreements for 380 million doses from COVAX.[41]
