Yep. It looks like their traditional dead virus vaccine is not working or has not worked.China is taking drastic action against its own people
hundreds of millions of chinese are locked out of their jobs
instead people are forced to remain at home without food and water
my guess is that communist chinese vaccine is no good and the dictatorship refuses to admit it
They are trying to create their own mRna vaccine as we speak....from what I've read.

1.4 billion doses later, China warms to using mRNA COVID vaccines
After long promoting their local options, China may finally approve the BioNTech jab.
