China's coronavirus vaccine may begin mass output this year

A front-running Covid-19 vaccine candidate being developed in China is expected to be available as soon.

A report published in the official Wechat account of China's state-owned Assets Supervision and Administration Commission said the vaccine might be available by the end of this year, reports the China Daily.

Beijing Institute of Biological Products and China National Biotec Group Co are jointly developing the vaccine.

It has completed phase II testing and may be ready for the market at the end of this year or early next year, said the report.

The production line for the vaccine will be fully disinfected and closed in preparation for output to start Saturday, and will have a full manufacturing capacity of 100 million-120 million vaccines each year.

Drugmakers are racing to develop a cure for the contagion that has so far killed at least 365,000 people.

More than 100 vaccines for the virus are being developed globally, but only a handful have made it to the crucial and final human clinical trial stage, with Chinese scientists leading the way.

In total, five vaccines developed by Chinese companies are being tested on humans, the most in any country. Beijing has mobilized its health authorities, drug regulators and research institutes to work around the clock with local companies to come up with the world's first successful one for Covid-19.

The vaccine candidate from Beijing Institute of Biological Products and China National Biotec Group employs a killed version of the novel coronavirus that can still trigger an immune response. Such inactivated vaccines have been developed for many years to protect populations from diseases including polio and hepatitis.

While inactivated vaccines may be slower to develop initially, their familiar path to mass production might allow them to overtake shots made by newer, cutting-edge approaches.
