A #langsec take on berthub.eu/articles/posts…:

Okay, so basically the reason mRNA vaccines work is 1) a parser differential between how the immune system interprets an unfamiliar token (the πŸ”± nucleoside) and how ribosomes interpret it, 2/

and a subtle semantic bug arising from disparate handling of different representations of an ambiguously representable parse result. The language of mRNA is nondeterministic, and that’s exploitable.
