That wasn't my point. There is evidence that Omicron is milder, just not in the limited UK data, which is what the report is based on. As I said, nothing wrong with the report nor it's findings, just the headline.
There isn't, not yet anyway, not for headlines like that which are written for UK readers and shared by people in the UK, and have been for weeks. There's not enough evidence to have care free policies or actions etc.
In SA it largely "appears" milder, as more people have been infected/ vaccinated, prior to this wave coming. That doesn't mean it's milder though, it just means they now have better protection. Car crashes aren't milder now, we just added seat belts and air bags, which lessened the impact. If you take those protections away, the new results would be the same as the old results.
But, and it's a key but, as it infects more, and faster, there would be far greater potential to overwhelm healthcare, especially if there was no immunity through infection or vaccination. This pretty much would have doubled the IFR, like it did in India. There is potential to do far more damage, potential which the other strains did not have.
If we had Delta or Omicron in March 20, it could have been 5 to 10x the deaths, even if we did still lock down, had we not done that, it would have been even worse than that.
The FT headline compared 15,000 Omicron cases to 100,000 Delta cases in the UK, and it showed no difference up to now in severity, in the UK, it just showed we're better protected (which we are).
We've had good protection for ages, which is why Delta "appeared milder". It wasn't milder (it was worse), we had just vaccinated 30m people before it got here.
There are some new lab studies showing it might have less potential to cause disease in the lungs etc, which is great, but we're not really seeing it yet in UK data, hopefully we do.
Like I keep saying though, we don't know yet, the experts are saying we don't know yet, so I wouldn't be trusting any headlines saying "it's milder" or "it's miles worse", the right headlines are "we don't know yet".
