for me it’s the data collection methods not being transparent enough, coupled with the behavior of the state being even less about an individual but more about reputation performance metrics

other governing systems could have the same result, but the current vaccines on my shortlist have data collection thats tolerable for me and the mRNA ones are at the top of my list by along shot.

Feel free to correct anything inaccurate if there is good data on the China one (or if there are multiple vaccines from organizations in china)
