Solid article:
'could imply a meaningful difference in susceptibility to infection between the vaccinated and the previously sick, since most of South Africa’s “immune wall” was built in previous waves, whereas most of Europe’s was built through vaccination'

'And while we should all be rooting for a fast crest and decline, there is also the possibility that Omicron is not overwhelming the global pandemic so much as unfolding beside it in parallel—'

'offering perhaps little additional immune protection against other variants, including future ones, and possibly leaving an ongoing Delta wave almost intact once, or if, Omicron subsides.'
