Vaccines

Sinovac's commercialized vaccines include Healive (hepatitis A), Bilive (combined hepatitis A and B), Anflu (influenza), Panflu (H5N1) and PANFLU.1 (H1N1). Sinovac is currently developing a Universal Pandemic Influenza vaccine and a Japanese encephalitis vaccine.[4]

Sinovac is also developing vaccines for enterovirus 71 and human rabies. Its wholly owned subsidiary, Tangshan Yian, is conducting field trials for independently developed inactivated animal rabies vaccines.

COVID-19 vaccine development
Main article: CoronaVac

In mid-April 2020, China approved a clinical trial for a candidate COVID-19 vaccine developed by Sinovac.[5] The vaccine, called CoronaVac, is a chemically inactivated whole virus vaccine for COVID-19.[6] After mid-2020, CoronaVac was in Phase III clinical trials in Brazil,[7] Chile,[8] Indonesia,[9] Philippines,[10] and Turkey.[11]

In China, CoronaVac is already being given to thousands of people under a national emergency use authorization to prevent COVID-19 infections.[12] Instituto Butantan has said the vaccine is between 50% and 90% effective in Brazil, but withheld full results at Sinovac's request, raising questions about transparency as it was the third delay in releasing results.[13][14] Separately on December 24, Turkey released Phase III results from an interim analysis of 29 cases which showed an efficacy rate of 91.25% based on the data of 1,322 participants in a trial involving 7,371 volunteers, a confusing readout compared to Brazil.[15][16][14]
