In Covid-19 vaccine race, China inoculates thousands before trials are completed

This has raised concerns over the safety of drugs that have not completed standard testing. China is inoculating tens of thousands of its citizens with experimental coronavirus vaccines and attracting international interest in their development, despite expert concerns over the safety of drugs that have not completed standard testing. China launched a vaccine emergency use programme in July, offering three experimental shots developed by a unit of state pharmaceutical giant China National Pharmaceutical Group (Sinopharm) and US-listed Sinovac Biotech. A fourth Covid-19 vaccine being developed by CanSino Biologics was approved for use by the Chinese military in June.
