I think we can't say which effects are at play here though without waiting for more numbers. Next to reports in e.g. VAERS; by now there are many reports by different real user accounts from different nations reporting severe side effects and deaths. There is a lot of tribalism, totalitarianism and unscientific overconfidence from those who decided for the vaccine as well. For them such reports are either pure statistics of large numbers (which I agreed with at first but wouldn't be so confident about anymore) or collateral damage (which is extremely cynical, given that the damaged people are often young and healthy without high risk from covid and just "wanted to do the right thing" or get certain freedoms back).
A less severe but suspicious and little explained side effect - the menstrual issues - are quite widespread, but are dismissed as hysteria..
