Your mode of thinking is linear convergent (interpolative) dominant, so you can be written into cognitive sinks. A mental prison of sorts.
Forget all that. Return to first principles.
Q1) What is the definition of safe and effective?
Answer: Safe is defined as having a profile not different from placebo, they use other vaccines or adjuvant as placebo. Effective is defined as "creates an antibody" which seems to do "something". That's it. There is nothing else.
Q2) Does the vaccine even work?
Answer: No, not really. If you give an infant a hep B jab to induce Th2 immunity (allegedly), then by 8-12 or so their antibody titres have already dropped to near undetectable levels. It doesn't last, to the extent it ever worked at all. The profile is similar with other jabs, antibody titres drop and with subsequent boosters they don't rise as much and don't last as long. This seems like a characteristic of Th2 response based immunity, and is not a matter of vaccine platform so much.
Q3) Is it even necessary?
Answer: No. Better methods have been known since the 1920's, they were just ignored, buried, or otherwise wiped out. Vaccination has mostly stolen the credit the belongs to civil engineering, sanitation, and other practices. Vaccination causes disease, not the inverse.
Your "which would you prefer" is known as Ericksonian hypnosis. You repeatedly posit malformed and leading questions/statements with the embedded assumption that their axioms are already a given. This is to put you in the moment and then react based on it being true. It's hypnosis, plain and simple. Now that being said, don't take this the wrong way. You yourself are very likely not a witting hypnotist, more likely this is just your unconscious mind repeating what was done to you onto others. I interpret this as it knowing it doesn't add up and signaling for help from the group. I am here to help. It's that simple.
