GUANGZHOU, Jan. 31 (Xinhua):China's renowned respiratory-disease expert Zhong Nanshan said Sunday that the mass inoculation of homegrown COVID-19 vaccines underway in China shows the vaccines are safe and effective.
The two vaccines currently in use in China, the China National Biotec Group (CNBG) Covid-19 vaccine and the CoronaVac vaccine developed by China's Sinovac Biotech Ltd., are both inactivated vaccines that are relatively safe, Zhong said at the launch ceremony of an event held in south China's Guangdong Province to promote the use of technology in COVID-19 prevention and control.
