Going to play devil's advocate here. I won't reject the vaccine on principle. I will wait and make an informed decision based on reason and logic.

I will be looking at several factors. How safe is it, 2 months after general public availability? How hard is it being pushed or forced on people? Are the side effects worse than the virus? Will I be excluded from employment? Do I have to show vaccine papers to travel? How hard will it be to forge papers to get past the checkpoints?
