I think things tend towards disclosure. We had coverups in the UK of rape gangs operating in northern towns which was eventually came to light after many years. I think if there are significant vaccine harms they will come to light. I don't know that if those harms exist they would have come to light by now.
The more people are involved, the most likely it is that it will be leaked shortly after. Intentionally harmful vaccines would incredibly hard to pull off.
But here, you're not in a conspiracy theory (or conspiracy myth as some would say). You have a falsifiable theory, "This specific vaccine have harmful side effects", you're not the only one. In France, we thought the HB vaccine increased SLS risks for a decade+: it was further enhanced by allergic reactions to some bad dosage, and some double vaccination during the 93 campaign (my mother was double vaccinated and reacted poorly the second time).
I know several people who waited for the non-RNA vaccine because they wanted to wait for more data before using new techniques, it isn't a conspiracy theory, just prudence. I disagree but i certainly respect the choice.
