"Immunity" begins by Meaning "100% protection."
That's what "Muni" meme connotes in the universe of Indo-European words "Mana" is Immanent within.
Then "Immunity" becomes decoupled from this 100% Protection Meaning ("Meaning" too is part of "Mana" meme).
We get to the 100% Immune Evasive" meaning of "Immunity."
"Immunity," though, as a Semantic Mantic magical 🪄Bat-Signal🦇 has not lost its "Mana."
Dissemblers notice, without getting why (they see the magic🪄 in Muni, not what it Means), they can further their projects by using the "Mana" of the hypnotic sound of "Muni" in "Immunity" (which, sadly, mohilises, seduces & lulls others into the grave).
"Herd Immunity," "Hybrid Immunity" & the GBD "Immunity Community's" memes (Mana's also in Community (a Remainder from pre-Indo-European society before "Monarchy")).
So they Summon this Mana & Communicate their own project into others' Minds by persuading people infection confers Immunity to that which one is infected ⭕️🙄.
Beware the Mana of those promising qualified rhetorical "Immunities" which don't provide 100% protection or ANY protection at all.
What these GBD Magi🪄are mobilising is a meme forged in the first Indo-European language community in eastern Ukraine's river valleys ~4,000-3,500BCE.
"Muni" forged its Mana as Meh1 = To Measure in ancient Ukrainian (PIE).
A story for another day.
I'm a Buddhist, I didn't know the word Mana, but I feel what you write
