Is there anywhere you could actually access any data that you can completely trust? I too have a relative who regrets taking a vaccine, as she's been having suspicious long term symptoms until now - she took the vaccine in Spring. Nothing in the 43k Pfizer study would indicate that such symptoms could appear, and maybe it is a coincidence that those symptoms started appearing after the vaccine. And of course it is anecdotal, but still it makes me vary at least about the Pfizer study. Symptoms seem to be related to blood flow issues in the legs, and getting this tingling sensation. Since it has happened to a relative I trust and who's otherwise pro vax, I'm slightly inclined to also believe other anecdotal stories, but obviously I can't use that as an evidence.
