As far as I see, some people are questioning why EU didn't prefer Chinese or Russian vaccines. I know only one of the Chinese vaccines: CoronaVac (developed by Sinovac)
We still don't have clear phase 3 results. The announced results (by Turkey, Brazil, Indonesia) are so different. It is not easy to trust it at the moment.
BUT WE ALREADY VACCINATED ALMOST TWO MILLIONS IN TURKEY :D
So the real results are coming... Just wait a couple of weeks more.
