China said its four COVID-19 vaccines may be ready for use by the public as early as November.
An official with the Chinese Center for Disease Control and Prevention (CDC), Guizhen Wu, gave the timeline in an interview with state TV late on Monday.
China has four COVID-19 vaccines in the final stage of clinical trials.
At least three of those have already been offered to essential workers under an emergency use programme launched in July.
Medical staff and border inspection officials, were the early users of the vaccines.
The government authorised the “emergency use” of the vaccine on July 22, Zheng Zhongwei, director of the National Health Commission’s (NHC’s) science and technology development centre, said in an interview with state broadcaster CCTV.
Phase 3 clinical trials were proceeding smoothly and the vaccines could be ready for the general public in November or December, Guizhen, CDC chief biosafety expert said.
Guizhen who said she has experienced no abnormal symptoms in recent months after taking an experimental vaccine herself in April, did not specify which vaccines she was referring to.
A unit of state pharmaceutical giant China National Pharmaceutical Group (Sinopharm) and U.S.-listed Sinovac Biotech SVA.O are developing the three vaccines under the state’s emergency use programme.
A fourth COVID-19 vaccine being developed by CanSino Biologics 6185.HK was approved for use by the Chinese military in June.
Sinopharm said in July that its vaccine could be ready for public use by the end of this year after the conclusion of Phase 3 trials.
Global vaccine makers are racing to develop an effective vaccine against the virus which has killed more than 925,000 people.
Leading Western vaccine makers pledged earlier this month to uphold scientific standards and reject any political pressure to rush the process.
