The most confident batch number fan fiction ever written

A sprawling conspiracy manifesto claiming vaccine batches were intentionally tiered by lethality, with catastrophic formulas mysteriously targeted at veterans and dissidents while politicians got saline placebos. The author breathlessly invokes a shadow research team that "couldn't get peer review" (mysteriously publishing on a decentralized server instead) and assigns percentages like they're throwing darts at a calculator. This is what happens when someone discovers batch numbers exist and decides they've cracked the code to systematic eugenics via alphanumeric suffixes.
