Omicron definitely changed the calculus of the vaccines and public health restrictions. Pre-omicron, there was hopes that COVID might follow measles and be vaccinated almost out of existence. Putting restrictions on the unvaccinated wasn't just a way of encouraging them to get the jab, it was also a way to protect people from getting COVID in the first place.
With omicron, COVID spread rapidly among the vaccinated as well, becoming more like influenza than measles. Getting infected with COVID now seems less scary and more inevitable. When almost everyone you know has gotten mild cases of COVID at this point, you're not really worried about getting it yourself or spreading it to others. In this sense, it doesn't really matter if there are unvaccinated people in the restaurant you're eating at. Therefore, there is a case to be made for reducing public health restrictions and beginning to treat COVID more like the flu.
One issue remains, however. Unvaccinated people are still more likely to get severe illness and take up spots in the hospital. There are still 160,000 Albertans above the age of 40 who have not had a single dose. If hospitalization rates are somewhere between 1% to 5% for this group, we're still talking about thousands of potential hospitalizations and hundreds of potential ICU cases. So it may still be quite a while before our health care system gets back to anything looking like normal. And there is a distinct possibility that Kenney will once again have to crawl back to the podium announcing new restrictions that he promised were gone for good, because a new wave has pushed us back to the brink.
