Six month immunity is well supported, twelve months is probably significantly too long.
Whoa, that’s surprisingly specific! How do we know it’s shorter than 12 months? Do we know many cases of reinfection?
What about cross-strain immunity? And how well do we know how many different strains there are, which of them are circulating where, different outcomes etc?
