Michael Crichton’s 1969 The Andromeda Strain is a medical thriller about preventing a pandemic — FROM SPACE!
Dispatched to retrieve the SCOOP satellite from the isolated Nevada hinterland where it landed, government agents enter the small town of Piedmont. They report that the sidewalks are littered with dead bodies, then abruptly succumb themselves.
SCOOP was intended to retrieve lifeforms from the near-Earth space environment with an eye to weaponizing them. It seems that the mission has succeeded beyond its creators’ wildest dreams.
