If you look at the studies for these vaccines, and take a look at how many people got side effects from the placebo injection (even things like myocarditis), that should tell you the majority of what you need to know. Same for most pharmaceutical testing, almost all people getting placebo get side effects of some type. I bet it's even worse in the past 20 years with the internet being so prevalent, if you are in a phase 3 study, you can look up the side effects from the phase 1 and phase 2 studies and that will inherently effect the outcome (what side effects you yourself end up with), regardless if you get the real drug, or placebo.
