amom,
we should not read about China at all, it is a different world. We don’t know how many people died there. But look at AUS/NZ – how man lives these countries were able to save by their zero-covid policies (of course, being a remote island/continent helps also). Their path forward seems pretty simple now: there will be omicron-specific vaccine in 2 months, they’ll use it and open again. If new variant comes, it will take another 3 months to make a vaccine, they’ll close for 3 months.
“natural immunity best” means that you are OK with people getting sick, some seriously, some dying, especially old and Roshei yeshivos. Vaccines have similar benefits to immune system as natural infection, similar or less risk of immune system side effects (myocarditis) and no risk of damage to lungs and other organs produced by “natural immunity”. This means vaccines beat natural immunity by “kal vahomer” principle. I do not understand how one interprets Torah to come to the opposite conclusion. Maybe we are coming from different facts. Please explain.
