Of course I do. Your body creates antibodies to viral proteins or particles and develops memory to them. In this case the antigens are created by your own body via injected mRNA enclosed in lipids, not an injected weakened or dead viruses.
So…you proved you don’t have any idea. For illnesses like COVID-19 it is key for a vaccine to be applied to as many people as possible to make it harder - in the final consequence impossible - for the disease to spread.
That’s the case with a vaccine to any contagious disease. Life has trade offs. I prever not to live under an authoritarian state. I don’t think hive-minded harm avoidance is the be all and end all of existence.
