Fine to take a vaccine that is extremely dangerous and may protect you from catching a cold (or not), but not to take a blood transfusion that is potentially dangerous but could save your life. The blood transfusion risks are mostly compatibility issues and potential for getting a disease. The vaccine risks are far less manageable, and include autoimmune diseases of every type (including type 1 diabetes), cancer, and poor fertility.
Plus, there is evidence of second-hand vaccination. People that get the torture shot shed spike proteins that infect others, spreading this vaccine from person to person. (And not just as in getting super coronavirus, either.) They disfellowship people for smoking based on that second-hand smoke effect, but they won't for taking the vaccine that has even worse second-hand effects.
