A Chinese inactivated vaccine against Omicron variants was on Tuesday approved for clinical trials by the National Medical Products. Administration.
The vaccine, developed by the China National Biotec Group affiliated with Sinopharm, has been under research since December 2021, the company said.
It added that preliminary tests, such as safety evaluation in animals and immunogenicity research, showed that the vaccine could produce high neutralising antibody titer against various variants including Omicron.
In the clinical trials, a randomised, double-blind, and cohort study method will be adopted among people aged 18 and above that have inoculated two or three doses of the coronavirus vaccines to evaluate the safety and immunogenicity of the inactivated vaccine. (Xinhua/NAN)
