China has approved its third coronavirus vaccine for the second phase of clinical trials as it reported 12 new COVID-19 cases, taking the total number of infections in the country to 82,816.
The state-run Xinhua news agency has reported that an inactivated vaccine developed by Wuhan Institute of Biological Products under the China National Pharmaceutical Group (Sinopharm) and the Wuhan Institute of Virology (WIV) has started its clinical trials.
An inactivated vaccine consists of virus particles, bacteria, or other pathogens that have been grown in culture and then lose disease producing capacity. In contrast, live vaccines use pathogens that are still alive.
An adenovirus vector vaccine, developed by Institute of Military Medicine under the Academy of Military Sciences, was the first to be approved to enter a clinical trial.
