Mulder disappears before a scheduled meeting with Tad O'Malley, who has an interesting theory about his and other people's DNA. Dana herself, who's had her own DNA tested, discovers an anomaly in the DNA sequence. She believes the human DNA was tampered with when humans were given a vaccine shot. When a disoriented soldier arrives at the hospital, Dana realizes he has anthrax, which could lead to a worldwide contagion. Monica reaches out to Dana, who confirms her theory, which is all part of Smoking Man's plan for the world.
Did You Know?
Adenosine deaminase (ADA) - the gene product inhibited by the Spartan virus - is an actual enzyme. Hereditary defects in the enzyme can lead to a condition known as Severe Combined Immunodeficiency (SCID) which leaves patients at risk for severe infections like those depicted in the episode. A treatment for the condition is to introduce a functional immune system into the patient via bone marrow transplant like Scully suggests for Mulder. See more
The anthrax vaccine is a cell-free filtrate of the B. anthracis bacterium, meaning it does not even contain whole bacterial cells. It is utterly impossible for administration to result in disease. See more
