They may have started with Sinovac, but the current figures for vaccine doses administered are:
Astra Zeneca 49 million
Pfizer 48 million
Sinovac 27 million
Sinopharm 15 million
Moderna 7 million
80% of the population have had two jabs, 40% have had three, 10% have had four.

Sinovac and Sinopharm aren't totally ineffective, they're better than no vaccine but not as good at keeping you out of hospital or the morgue as other vaccines. But none confer immunity, I've had four jabs (2x AZ, 1x Moderna, 1x Pfizer) but I still caught Covid last month after a trip to Malaysia.
To answer your question, Covid is neither coming nor going, it's here to stay.
