This man may be foolish in terms of his romantic assignations - but there's no evidence whatsoever to suggest that he didn't work on coronavirus, to the best of his ability
A highly experienced and reputable epidemiologist - who has worked on foot and mouth, MERS, ebola, dengue etc. - is somewhat unlikely to exaggerate his findings, for a media story.
Why would he? Experts like him build their reputations on being right, and ahead of the game - and although these chaps can't be right all the time - we're a lot better with them, than without them!
Trial and error (a lot of the latter) are an integral part of scientists' work - and they need a bit of luck too.
Like Fleming got, when he almost accidentally invented one of history's greatest drugs - penicillin.
