If it were the Chinese one they would do a livestream and tell everyone how great it is, if it were the oxford one it will be done quietly. They cant be seen to favour that pesky farrang vaccine over the Chinese one Xi wont like it. Notice all the fuss they made about the sinovax arriving yesterday news crews big Chinese flags etc? all that was missing was the marching band. The Oxford vaccine arrived yesterday also but quietly through the backdoor.
I bet he didn't but I can take a wild guess which one it will be.
