China approves Sinovac Biotech COVID-19 vaccine for general public use
BEIJING (Reuters) – Sinovac Biotech said on Saturday that its unit’s COVID-19 vaccine has been approved for use by the general public by China’s medical products regulator.
It marks the second vaccine approved for public use in China, after one developed by a Beijing institute affiliated with state-owned China National Pharmaceutical Group (Sinopharm) was approved in December.
Both vaccines, as well as a third candidate from Sinopharm, have already been used in China’s vaccination program which has administered over 31 million doses, mainly targeting groups at higher infection risk. A fourth candidate from CanSino Biologics is being used among military personnel.
Indonesia, Turkey, Brazil, Chile, Colombia, Uruguay, and Laos have granted emergency authorization for the CoronaVac vaccine developed by Sinovac Life Sciences, Sinovac said in a news release.
Approval of the two-dose regimen by China’s National Medical Products Administration is based on results from two months of late-stage clinical trials overseas, from which the final analysis data has not yet been obtained, Sinovac said.
Its Beijing-based unit Sinovac Life Sciences is expected to be able to produce over 1 billion doses per year in the form of bulk ingredient by February, it said.
Sinovac is also expanding its capacity to fill vaccine into vials and syringes, which currently lags its vaccine manufacturing capacity. It has also outsourced filling and finishing procedures to overseas partners.
China plans to provide 10 million vaccine doses to COVAX, a World Health Organization-backed global vaccine-sharing initiative that Sinovac, Sinopharm and CanSino have applied to join, the foreign ministry has said.
A Phase I and II trial in China showed the vaccine could safely trigger immune response for older participants and it is also being tested in participants aged three to 17.
Sinovac cautioned, however, that data for the protection rate among people aged 60 and above was “limited”.
“When the relevant institutions …use this vaccine, the necessity of inoculating this product should be evaluated in consideration of the health status and exposure risk of this age group,” it added.
VARIED EFFICACY RATES
Sinovac’s vaccine is being tested in Phase III clinical trials in countries including Brazil, Turkey and Indonesia, where varied efficacy readings had been released separately, without sufficient details made available to public.
