Herd immunity's newsy now, But herd immunity facing covid, Conjures cows...lazy and lowing And basking in pastures. Covid needs a hardier immunity, An immunity with menace... Perhaps, horde immunity... A rampaging, pillaging horde of immunity. Were I covid, I'd be in fear Far more from a horde Than I'd be from a herd. *A pandemic...for readers years after this, when covid's forgotten.
