Pim, I (maybe also like you?) find omicron's arrival discouraging, but knowledge has progressed, the vaccines have exposed our immune systems to the virus, and that should help us. We might still get contaminated but the probability that it is severe is smaller. The virus' evolution has been very unlucky for us while scientists' ability to make vaccines has been impressive. I don't think we should judge the vaccines on the virus' mutations (those were out of the picture at the time). There aren't many "easy", obvious policies to be made in the face of this virus, which has now become extremely difficult to contain with delta and omicron.
