> They just say you won't get herd immunity until about 60% are infected But even this is wrong, or at least, unsure.
Herd immunity relies on low (or zero) re-infection. It works for diseases like measles, where the risk of re-infection (after either infection or immunisation) is effectively zero. We don't yet know if re-infection with covids-19 is possible or not. |
