If you understand the basics of the mathematics of immunology, you would know that you don’t need anything like 100% individual efficacy to develop useful levels of herd immunity to prevent mass transmission. Even if you don’t think YOU need it, suck it up, wait in line a few minutes, take the prick in the arm, do it for the young children, oldsters, and immune compromised for whom the prevention of the flu is more important.
Ah, yes. All for the “greater good”. No thanks, the lesser good is what interests me.
