We shouldn't treat this as one disease , rather as three, Wuhan, Delta and Omicron . It's called break through when a vaccinated individual gets Covid-19 . The vaccination gave something like 96% protection for the original, 83% for Delta and here is where it gets interesting. .First the media were reporting 70%, then 50%, now 15% . The mRNA vaccines have two types of protection, antibodies and killer T-cells. My guess would be the 32 mutations to the spike protein on the Omicron virus fool the antibodies. Antibodies have a limited life in the blood . Thus the push for boosters. T-Cells are more of a cure than a prevention, no ICU time.
It's understandable why the general population wishing to get on with their lives, would agree to segregate the un-vaxxed. They were only 10% here in BC.
