We don't live in South Africa, the UK is very different.
Yes you are right there Dave. 
Life expectancy in South Africa is much lower than the UK generally, and a significant proportion of the population live in shanty towns in and around the big cities, Cape Town, JoBurg, Pretoria, Durban etc. They live cheek by jowl in poor quality housing often without running water or proper sanitation. They eat cheap shitty processed foods. They are more than likely to smoke and drink poor quality alcohol in the shabeens. All this contributes to generally poor health and other diseases like TB are not uncommon. South Africa has a veneer of a developed first world country, but scratch the surface.....
So believe me, with their low vaccination rates, if Omicon was the killer super mutant virus that the British government and corrupt media would have us believe, we'd certainly know for sure as people would be dropping like flies in South Africa and then maybe I'd sit up take notice of the so called Omicon Emergency.
They're not though.
As you are so well versed in Virus information with all your years of research into sars cov 2 , are you saying that Omicron definitely won't mutate to a more lethal Variant 
so we have nothing to worry about then ? no need to exercise any caution ?
perhaps you should pass your findings on to the UK Government 
Maybe Boris will invite you to a few parties 
No of course not. Where did I even imply that? 
It's just that from what I've seen and read so far I don't think Omicon warrants the hysteria that is being stoked up.
Oh and I'm vehemently against the introduction of vaccine passports....
So you aren't a virologist with years of research and knowledge into Sars Cov 2 with all the answers

then maybe the Governments cautious approach is not as crazy as you think after all

Look how far Covid has progressed in 2 years , even the real experts know relatively very little yet .
As for what you have "seen and read so far" ,how much reading and seeing have you done ?
I assume you have not had a relative or friend die of Covid yet ? or can't get hospital treatment because Covid levels are so high and hospitals full to bursting

"Hysteria" or just the news reporting what is going on

if Covid can join with Flu to be much better at spreading then what's to say it won't mutate again with something like cancer ,making it more deadly and potentially making cancer transmissible

such ideas seem madness ,but 2 years ago who'd of thunk the world would be on it's arse with a pandemic

Covid passport a violation of your civil liberties perhaps ?
So if an anti-vaxxer, who couldn't be arsed to get a covid test before going to a concert or after it, then gives you Covid at the supermarket ,possibly making you seriously ill ,struggling to breathe ,organs turning to mush (or dead) .how violated would you feel then ?
Is it really fair to expect the caring people of the NHS to try and cope with another big wave for crap pay, simply because a few people CBA to follow a few simple rules like wearing a mask ,take a test or whinge about civil liberties

doing a LFT takes about a minute ,then wait 15 mins for a result while doing something else ,register the results in a few clicks of the mouse .simple
We may not like all these measures BUT there are no quick fixes ,until we know all the answers and have a solution, we have to be cautious
