I cannot trust the institutions pushing this vaccine at all. At worst, I trust the opposite of what they say about anything politicized. But let's just say I don't trust them. In the absence of a trusted authority, I can only make this decision based on my own research. Unfortunately I am not qualified to interpret the data meaningfully, and I truly believe that if there was data suggesting that the vaccine was equally dangerous to the virus, it would be suppressed.
What remains is essentially a total vacuum of information. I then have to make decisions based on intuition and the error bars I perceive. What I expect is that the publicized covid numbers are better or equal to the reality, and the vaccine danger is worse or equal. The publicized numbers for covid give me essentially a zero risk of any problems, because I am young, fit and healthy. The real numbers are going to be even better. Meanwhile, the vaccine problems don't seem to be fewer for young people, but just kind of random. I also know what to expect from a respiratory virus, because I've had those a number of times. I have no idea what to expect from a MRNA vaccine, whether there could be problems that appear years later, etc, and I cannot trust any authority that says there is no risk.
There is also the aspect of direct action. If I get covid, darn that sucks but people get sick and that's life. If I get some bad side effects from an untrusted injection, I did that to myself and it will feel mentally much worse. All of this is to say, I don't care at all if I get covid, because I'll be fine. I won't inject myself with an untrusted medicine to avoid that.
