You mentioned I said something very very wrong, but it's not clear to me if this is a language or fundamental issue. For instance if I say, as I have tried to enunciate above, "if herd immunity is too low, vaccines may do more harm than good at a social/epidemiologic level", does that still seem very very wrong to you? To be clear, your above comment gave the impression that you thought that a low herd immunity could not increase deaths due to disease compared to no herd immunity at all, which is wrong and was probably the reason why you were downvoted.
