Ambrosia

"The only known vaccine against the 'Gray Death.' Unfortunately, it is quickly metabolized by the body making its effects temporary at best."

- Description of Vial of Ambrosia Ambrosia is a vaccine[note] created by multibillionaire Bob Page for the Gray Death. A single dose (20) will temporarily cure any individual who uses it, and will provide up to 48 hours of immunity to the virus. After 48 hours, if the individual does not continue using the medication, they will once again be at risk of contracting the Gray Death. Ambrosia is currently the only known vaccine for the Gray Death and is solely produced and monopolized by VersaLife.

Design
Ambrosia is described as a "non-organic compound containing eutactic components". The Ambrosia vaccine consist of ROM modules which attach themselves to the Gray Death nanites, thus acting as a "hardware-lock". Like the Gray Death, it can only be manufactured using a Universal Constructor.

In-game
The beginning of Deus Ex involves the UNATCO agent JC Denton recapturing several containers of Ambrosia which were stolen by the NSF in an attempt to return it to the people. The NSF attempted to ship a sample of Ambrosia to Hong Kong, with the hope that Tracer Tong would be able to reverse-engineer the vaccine and produce it independently.

A vial of Ambrosia can be found on the Majestic 12 owned PRCS Wall Cloud. Later in the game it can be given to Stanton Dowd to cure his recently contracted Gray Death.

MJ12 own and control every functioning Universal Constructor on the planet. Considering that a UC is needed to manufacture Ambrosia, they alone decide how much Ambrosia gets manufactured and who it gets distributed to. In this way, MJ12 use the Gray Death and by extension, Ambrosia, as a means to control and manipulate others into doing their bidding.

Trivia

 * The name "Ambrosia" is one of many symbolic names taken from Greek mythology. In Greek mythology, Ambrosia was the food of the gods, which gave them immortality.
