One of the remaining three was said to be an experimental vaccine under clinical trial (phase two), having been developed by the Hong Kong-listed CanSino Biologics Inc and the Beijing Institute of Biotechnology.

There are now no approved vaccines or medication for the COVID-19 disease, which has killed more than 120,000 people worldwide and infected almost two million.

China approved clinical trials for two types of inactivated vaccines for COVID-19 on Tuesday, announced China's Joint Prevention and Control Mechanism of the State Council.

Chinese teams were also racing to develop vaccines using other methods including using attenuated influenza virus vectors or injecting specific nucleic acid.

Vaccine testing phases usually involve lab tests, followed by animal tests, then small groups of human tests followed by larger groups.

Another vaccine, being developed by the Wuhan Institute of Biological Products and the Wuhan Institute of Virology, was approved on Sunday, he added.

The vaccine is developed by genetic engineering methods and is used to prevent diseases caused by novel coronavirus infections, state-run China Daily reported on Monday.

US company Inovio Pharmaceuticals is also conducting human trials and is working with Chinese researchers to begin a study with the drug in China.

Scientists say they can use research from SARS and MERS to help create a COVID-19 vaccine.
