Ad5-nCOV is the trial vaccine that has been approved for use by the People's Liberation Army (PLA), but not for civilian use.
So far, however, this trial vaccine has passed only stages one and two; it needs to pass a third stage to be licensed for use. But, the spread of COVID-19 in China isn't suitable, so an agreement has been reached with Canada for stage three testing.
There are another six candidate vaccines still in development and testing / trial in China.
