R0 does not exist outside of context either. We like to think to R0 has being whole numbers. R2, R4 etc. Or small decimals.. R1.5.. But really, _everyone single person that gets infected_ actually lowers R0 a tiny bit, as they are now recovered. Combine this with the late breaking evidence that there is some cross reactive immunity in T cells with other coronaviruses, and we see that R0 is completely meaningless without more data. If R0 is a lot higher, lets say 7.5 or some absurd amount, and we do have such a cross-reactive immunity, herd immunity may come at 40%. See, it needs context.
