China greenlights first domestically produced mRNA Covid vaccine.
China has approved its first mRNA Covid-19 vaccine developed by CSPC Pharmaceutical Group, which targets the Omicron variant and was tested with over 5,500 people. The vaccine's safety, immunogenicity, and efficacy have been demonstrated, but additional details were not provided. China had previously approved only inactivated vaccines made by Sinovac Biotech and Sinopharm Group, which elicit lower levels of antibody response compared to mRNA vaccines.
