The 'big flaw' in the SA observations lie in in the fact that they have huge seropositivity rates, I believe well over >50% of the population has had COVID, many of them contracted multiple strains. And - they've had quite a lot of people die already from it. So that Omicron is not hugely lethal among a population with 'natural' tolerance and where a good swath of the ill have been killed ... is maybe not so surprising. Maybe there is a good answer to this but the SA reports I have seen don't seem to directly speak to this issue.
