Science fiction plot: It's a means to extinguish a group of people. Laws are passed allowing Forced vaccinations. Sounds familiar. The masses would make fun of conspiracy theorists and side with the nefarious powers (like with vaccine manufacturers) Eventually, but perhaps too late, there would be the realization that their race or creed got something else in their shot. I'm thinking Chris Pratt and Priyanka Chopra. But as voluntarily sterilizing one's self with all the possible side-effects of messing with hormone levels? Doesn't sound very marketable. Must be shooting for a small population of extreme conditions and illnesses which greatly reduce it's worth as a viable money maker.
