Coronavirus vaccines being developed in China may be ready for use by the general public as early as November, an official with the Chinese Center for Disease Control and Prevention (CDC) said. China has four Covid-19 vaccines in 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.
Global vaccine makers are racing to develop an effective vaccine against the virus which has killed more than 928,000 people. Leading Western vaccine makers pledged earlier this month to uphold scientific study standards and reject any political pressure to rush the process.
