At around 22 days from first community spread to peak everywhere, regardless of the vaxx rate or NPIs, says it all. Of course policy should change and it will, but it's the same everywhere, as governments react to the novel situation with the usual caution. I dunno if we can even slow it down enough to save the hospitals from being screwed by volume and this omicron wave appears to be cresting. It is killing and hospitalizing a fraction of the people vaxxed or unvaxxed than delta and vaccination protects most folks from bad serious illness and death. Next we will deal with O2, but it appears to be no more virulent than O1, but more contagious and O1 helps with immunity against it as well as delta.
We are learning to live with it, but it takes time to adapt policy, but we are seeing plenty of evidence that covid policy is changing in many places at once. It will be interesting to see what will happen in New Zealand, a land of highly vaxxed virgins who are about to get slammed, ditto for China and they have shitty vaccines!
