"That says it all ....." S2 #540

That's not a refutation of fact. It's contempt, dismissal of process.
I understand an mRNA flu vaccine CAN differ on molecular level from the legacy variety.
Must it absolutely do so? That the conventionally manufactured molecule can't be manufactured with mRNA, indistinguishable by its process of manufacture?
If no, what's the difference?

"BTW, you do realize that headline writers aren't always the authors of the article in question. " S2 #540

Correct.
Pappy told me that at the kitchen table. The conversation was related to a headline he mentioned: Sticks Nix Hick Pix.

"I've lost track of the number of seminars I've attended where next day's newspaper article isn't exactly an accurate discussion of what the speakers said but the headline is even worse." S2 #540

Formal education / academe well recognized as our culture's traditional path to mastery.
It is not the only path.

If mRNA technology can not produce the same vaccine molecule previous vaccine manufacture technology produced, why not?

The obvious reason for asking:
if the vaccine molecule is indistinguishable, then citing legacy style produced vaccine as safe & effective, but mRNA as not, on what basis not?
