I guess we can look to places like Israel where there is nearly 100 percent, and the UK where there is a very high vaccination rate esp in the over 50s.

If you go to the gp/doctor and you tell them you are suffering issues after a vaccine they have to (by law) pass that on to the regulator and to the vaccine manufacturer. In Israel and in the UK reports to doctors about longer term side effects of the vaccine are within and below the expected ranges.

Reports on twitter may be high, reports to doctors remain low. You can draw your own conclusions.
