AKA: No, It's Not a Vampire Episode
The X-Files usually avoided doing episodes that were of their moment in history, which usually worked out for the better. "Ripped From the Headlines" tends to date your story, while except for the the technological limitations, most episodes of The X-Files are timeless. There are a couple of exceptions, most notably The Field Where I Died, which pulled most of its plot from the Waco standoff. But, while Blood doesn't pull much of its plot from then-relevant events, it seems to get dated by its details.
