Most people play their role in this sort of thing without being clued into any sort of explicit conspiracy. For example, my friend's PCP who attributed his newfound cardiac issues in his mid 30s to a mild COVID infection, and not the 3 Moderna injections he had had before that. No report, nothing to investigate or attribute. There are countless stories of people who suffered severe adverse effects in close proximity to a vaccine dose being similarly shrugged off as hysterical by their doctors.
