Lots of speculative fiction written in the past 30-40 years which posit a "targeted weaponized DNA virus". One story discusses deep-diving into the DNA of niggers and targeting them with a fast-acting virus which when deployed causes a near instant quietus on their cardiac muscles resulting in an instant cardiac arrest. The story line went on to describe how the "clean up" effort would work; imagine millions dead in the streets, ghetto housing, along with the concomitant fires caused by ghetto housing catching fire when the stove cooking pig snouts boils over, etc. etc. I'd like to see such a thing if it including all juden. I'll volunteer to drive the backhoe scooper.
