Im not sure anyone really knows those numbers. The CDC stopped counting breakthrough Covid infections unless you were hospitalized months ago. The Israelis did count them so their data is more complete. I am guessing that is why they were early in recommending boosters.
Covid medical expenses have been covered by the cares act but that wont last forever. Insurance companies are trying to limit Covid coverage which may push a bunch of people into medical bankruptcy. A serious covid hospitalization if you survive is a very expensive ordeal.
