China approves new COVID-19 vaccine for clinical trials
BEIJING. KAZINFORM A new COVID-19 vaccine developed by China's Sinopharm has recently been approved for clinical trials.
The new recombinant COVID-19 vaccine, developed by the National Vaccine & Serum Institute, a R&D center of Sinopharm's bioscience subsidiary the China National Biotec Group (CNBG), got approval from the National Medical Products Administration on Friday, the CNBG said on its official Weibo account on Saturday.
The vaccine is based on the structural features of the receptor binding domain (RBD) on the virus' spike protein (S-protein). It uses genetic engineering to grow harmless copies of the virus S-protein to induce neutralizing antibodies, Xinhua reports.
The company said that recombinant vaccine technology is mature and suitable for large-scale production. The production does not require facilities with high biosafety levels since the process does not involve live viruses.
The recombinant vaccine is the company's third COVID-19 vaccine. Last December, an inactivated vaccine developed by the Beijing Biological Products Institute Co., Ltd. under CNBG became the first Chinese COVID-19 vaccine to have conditional marketing authorization.
