If the report is true
What report? I went through the article just to make sure, and there are no mentions of any “reports” of such a deal being made for vaccines in exchange for Uighur Muslims. The only thing referring to this in the article is the accusation of this happening over loosely linked mentions of recent vaccine sales and extradition agreements being signed between the two countries.
The opposition party in Turkey made the accusation, but there have been no connected “reports”.
