notice, we still have no data of any sort for sinovac, even though supposed phase 3 trials were completed months ago.
the Chinese are refusing to publish or share the data with anyone. not even hong kong was given the data.

They won't submit to medical jounals, beyond vague PR releases that cherry pick the data.
