I think like most things it's much easier to think of the Covid-19 vaccination in terms of risk.
Not having the vaccination increases the community risk. For a small but not insignificant percentage of the population Covid-19 is a death sentence. It need not be.
Having the vaccination carries a very small risk that you will be crippled for life or even die. It need not be but this is because the vaccine is new and not fully tested.
Now to put this risk in perspective.
Driving a vehicle carries far more risk of permanent injury or death to yourself or someone else (community). If you walked into a car dealership and the salesperson started off telling you about all the risks involved in driving a vehicle you would probably decide the risks are just way too high and walk out.
Back to topic.
Those that got the vaccine, were you allowed to pick which arm got injected, was the derriere an option?
