The Last of Us: How Is Ellie Immune to Cordyceps & Why Didn’t That Bite Affect Her?

Ellie’s immunity to the Cordyceps fungus is a central element in “The Last of Us,” but what makes her body resistant to this fungus that wiped out most of humanity? Though hints at her resistance have been present since the start, The Last of Us Episode 9 finally unveiled the truth behind her extraordinary condition.

What makes Ellie resistant to the Cordyceps fungus, and why didn’t she transform into an Infected when bitten in The Last of Us? Let me explain.

Or simply:

Why is Ellie immune to the Cordyceps fungus in The Last of Us, and how did she avoid turning Infected after being bitten? Here’s a rundown on that.

How is Ellie immune to cordyceps in The Last of Us Season 2?

In contrast to other survivors in The Last of Us, Ellie’s resistance to the Cordyceps infection is not just a matter of chance. Instead, it’s rooted in a biological anomaly, and the secret lies in her origin, traced back to her birth.

In The Last of Us‘ Episode 9, a heart-wrenching flashback unveiled that my beloved character Ellie’s mother, Anna, was bitten by an infected while giving birth to me. Before transforming, Anna severed the umbilical cord, but not before the deadly Cordyceps fungus found its way into my system. Yet, instead of turning me, the infection miraculously altered itself to protect me.

Later on, Marlene clarifies that the Cordyceps within Ellie functions as a “biochemical signaler.” When fresh spores get into her bloodstream, typically via a bite, Ellie’s altered form of the fungus deceives them into believing she’s already infected. This prevents the disease from advancing to her brain, making her the sole known immune survivor.

Why the Zombie bite in The Last of Us Season 2 Episode 1 didn’t affect Ellie?

Episode 1 of The Last of Us Season 2 presents a new type of Infected, known as the Stalker. This advanced stage of infection is capable of moving on all fours and exhibits a chilling level of patience when hunting its prey. Unlike Runners who charge recklessly or Clickers who depend on echolocation, Stalkers demonstrate a keen intellect.

In a stealthy manner, this stalker pursues Ellie as she navigates dimly lit corridors, only to pounce on her at a later time. Following a fierce fight, Ellie manages to slay the undead creature, but not before it inflicts a bite onto her. Remarkably, her immunity prevents the infection from taking hold.
