CoronaVac

CoronaVac, previously known as PiCoVacc, is a SARS-CoV-2 purified, inactivated, and adsorbed vaccine candidate developed by SinoVac Biotech Corporation. It was developed by propagating the SARS-CoV-2 CN2 strain inside Vero Cells and inactivating it with B-propiolactone. In preclinical trials, PiCoVacc induced SARS-CoV-2-specific neutralizing antibodies in rats, mice, and the rhesus macaque. The antibodies were found to neutralize 10 representative SARS-CoV-2 strains. As of August 2020, the vaccine is being tested in numerous human clinical trials assessing its safety and immunogenicity.
