'''Vaccine "Metroid"''' is a cure administered by [[Galactic Federation]] scientists on [[Samus Aran|Samus]] to remove the [[X Parasite]]s inside of her body. It only appears on one occasion throughout the ''[[Metroid (series)|Metroid]]'' series, in  ''[[Metroid Fusion|Metroid Fusion's]]'' [[Galactic Federation]] HQ. In [[Metroid Dread]], Vaccine “Metroid” briefly appears in the introduction.

==Infected by the X==
In the beginning scenes of ''Metroid Fusion'', Samus is assigned bodyguard duty, guarding a Biologic Space Labs research team by the [[Galactic Federation]]. Samus and the researchers explored life forms on the surface of [[SR388]]. Thinking they had found a regular [[Hornoad]], Samus attempts to destroy the creature, to find that it mutates to a [[X Parasite#Yellow X|yellow X]]. The yellow X then attaches itself to Samus. Although there were no initial problems, once Samus drives [[Samus Aran's Gunship|her gunship]] back to a B.S.L ship, the X begins multiplying in her body.

==A Cure Discovered==

Samus becomes unable to operate her ship, and it slowly drifts toward an {{wp|asteroid belt|asteroid field}}. Her ships safety systems, however, eject Samus in an [[Escape Pod|escape pod]] before the impact. The escape pod sends Samus to [[Galactic Federation]] Headquarters, where scientists examine her condition. Since Samus was unconscious, they could not remove the [[Power Suit]] in its entirety. They surgically removed all X-infected suit parts that they could without causing Samus damage. It wasn't enough, though, as some X had embedded themselves deeply in Samus's {{wp|nervous system}}. Fortunately, one of the GF scientists discovered a cure to the X using a sample of the [[Metroid Hatchling|Metroid Hatchling's]] {{wp|DNA}}. The serum, named Vaccine "Metroid", was immediately injected into Samus's body. The [[Metroid (species)|Metroid]] cells immediately began taking over the X inside of her. The serum transformed Samus's [[Power Suit]], giving it Metroid properties. She was now vulnerable to [[Ice Beam|cold-based weaponry]] or freezing environments, and she could absorb the X as [[Power Up|power ups]].

==Samus's Revealed Thoughts==
''Fusion'' is unique amongst the Metroid games in that it reveals some of Samus's thoughts through text. These thoughts occur throughout the game, but become more scarce as the game progresses. Early in the game, these are some of her thoughts.

:''"I'd been assigned to watch over Biologic's research team, so I once again found myself on the surface of [[SR388]]."''

:''"It was there that I was attacked by a life-form I had never encountered before."''

:''"It was only later that I learned the identity of my attacker: the parasitic organism we now know as X. Unaware of my condition, I was returning to the station when disaster struck."''

:''"Once the X had infested my central nervous system, I lost consciousness and my ship drifted into an asteroid belt."''

:''"The ship's emergency systems automatically ejected the escape pod before impact. Biologic's vessel recovered it and transported me to Galactic Federation HQ."''

:''"However, during the journey, the X multiplied within me, corrupting large areas of my [[Power Suit]]."''

:''"It then came to light that the organic components of my Power Suit had become so integrated with my system that it could not be removed while I was unconscious. Large portions of my suit had to be surgically removed, dramatically altering my physical appearance. However, the X in my central nervous system were too embedded to be removed safely. I was given a minimal chance of survival."''

:''"Then, someone found a cure."''

:''"They proposed using a [[Metroid (species)|Metroid]] cell to make an anti-X vaccine. It seems that the [[Galactic Federation|Federation]] had managed to preserve a cell culture from the [[Metroid Hatchling|last infant Metroid]] from [[SR388]]. The serum was prepared and injected without delay."''

:''"The X parasites were immediately and completely destroyed."''<ref>{{cite|It was there that I was attacked by a life-form I had never encountered before.

==Trivia==
*[[Samus Aran|Samus's]] [[Power Suit]] must be surgically removed, suggesting that Samus is biologically connected to her Suit. This, however, contradicts other elements throughout the [[Metroid (series)|Metroid series]] such as the fact that Samus loses her Power Suit in ''[[Metroid: Zero Mission]]''.
*Vaccine "Metroid" is not a vaccine at all, as vaccines are only effective before a disease or illness is contracted, while this one was used during [[Samus Aran|Samus's]] severe illness.
*Although the [[Galactic Federation]] scientists are believed to have made a breakthrough by using Vaccine "Metroid" to combat the [[X Parasite|X parasites]], they are unaware that the [[Chozo]] initially created [[Metroid (species)|Metroid]]s to combat the X.
