Unless you are a front line worker or are high-risk, you won't be part of the first wave of vaccinations. By the time someone offers you a shot, it will have been give to tens of millions of people over several months (and well over 6 months for the Phase 3 participants).
At some point, you have to take a leap of faith. For all you know, it could take 10 years for negative effects to appear. Not being the first in line will tell you nothing that the trial didn’t already tell us, and waiting a year will tell you nothing about side effects in 2, 5, 10 or 20 years.
I choose to trust the scientists who understand the science of how these vaccines interact with the body. I would prefer to take a bet on them and be part of the solution rather than believing in some self-formulated risk analysis and remaining part of the problem.
Look, I'm sure they've tested. And I'm sure they've done enough to satisfy their regulatory burden.
Just saying I'm not going to be the first over the wall - I'll leave that to the eager.
