Peter: After you showed me the medical tests you had done... which to me indicated that we had been inoculated without our being aware... I needed to know 'inoculated against what?' So... since it appears I no longer have level blue clearance... I broke into Group archives and stole some of the Old Man's personal effects: specifically, a recorded transmission and his voice access phrase. I edited the transmission, I matched his voice code, I got level blue and I looked up the Marburg Virus.
Frank: What did you find?
Peter: It appears to live in an unknown host, somewhere in the Kaitoon Cave region of East Africa.
Peter: The Soviets - 'biopreperat' - sent men into the jungle to find it.
Frank: Jordan keeps having these reoccurring nightmares about monkeys.
Peter: Frank, you're daughter doesn't just dream, surely you must know that by now.
Frank: What about the Russians?
Peter: The object was to create a devastating biological weapon. The virus is genetically labile... it could exchange genes with plague, anthrax, smallpox, flu strains: which creates variant viruses, against which a human population has no immunological defence. Weapons grade anthrax takes approximately 8,000 microscopic spores to introduce an infection. The Marburg variant they created in the lab takes 3! Now in 1982 prions were discovered, and a prion is a protein that has no R.N.A; no life. So it would make the perfect weapon: it's immune to antibiotics, enzymes, can withstand the heat of over 600 degrees. A Marburg variant virus which genetically engineered with the prion... thereby creating the biological agent that would kill quickly, spread rapidly, and if the virus were neutralised the fused prion would finish off the host. When the Soviet Union fell the bioweapons facility near Pekeb was abandoned. The virus... Marburg variant PRP... a manmade virus that had never been exposed to the environment... leaked. Birds in the area... and birds were especially susceptible... became infected. And over the next three years they migrated to Alaska, to Northern Canada, to the American upper-mid-west. In 1986 a Wisconsin farmer, and his entire flock of hens, died from its effects. So it had undergone 'antigenic drift': it could be transmitted from birds to humans. But then as soon as that happened, the virus disappeared.
Frank: The virus... you're telling me it's back?
Peter: The man we found by the river last week?
Peter: ... family near San Diego, few days ago... village in China yesterday... a town in South America today.
Frank: The Group has a vaccine they gave to us.
Peter: Yeah, after '86 they developed a vaccine that could keep the virus in check once it entered the body.
Frank: So people could be inoculated.
Peter: There would never be enough material... to develop a universal vaccine. They only made enough for Group members.
Frank: And their families... And their families, Peter.
Peter: It was always about control, Frank. They're gonna expect us to stay with them now that they've protected us from this plague.
Frank: So watching our families die... that's protecting us?
Peter: What are you going to do?
Frank: Get your family, I have a place where we can stay.
