What we see in reality is that "medical professionals" like yourself are loathe to accept that reports of problems could be linked to the vaccine, even if they occur very soon after vaccination. Instead they are routinely ignored or ascribed as coincidences. For instance, the system is still totally ignoring the apparently widespread appearance of menstrual problems in women who have been vaccinated despite it being one of the top reports in VAERS. Female friends of my girlfriend are reporting this problem at a very high rate, yet as far as people like you are concerned it doesn't happen at all.
It seems very much like virtually none of the reactions that would intuitively be caused by the vaccine are actually being recorded as such. In that environment your confidence would be severely misplaced.
