I was thinking montopolis bridge which you see in the background at the start of the game, but not sure if its in the show
But never mentioned in the show confused me, so it isn't a physical location ?
Does the symbol signify something from The Last of Us?
Edit: ope, Fireflies symbol from TLOU.
Right! Spoilers below.



Reddit theory by a gamer, 5 years ago, confirmed correct by the show. (Ellie's mother Anna was bitten just before childbirth, and the placenta/umbilical cord passed the virus to Ellie in such a way that she could pass off as Cordyceps and be immune)

Reddit theory, more recent, unproven as far as I know (suggests that colostrum, the first breast milk that babies receive when feeding, is the antibody)

Page explaining game and show reasoning, saying that the game's explanation is more in-depth (antigenic titers of the Cordyceps)

The pregnancy/placenta, or the breastmilk of the second reddit theory, could be the bridge to "real life"; the natural vaccine(?) that Ellie gets as a result of the bite could be what "fights the fungus". I'm thinking antigenic titers or colostrum/breastmilk, since they don't seem to be mentioned in the show.
Likewise Reddit could also be a bridge to real life, and it's a Reddit theory specifically, but that feels less poetic in general XD
