A couple of weeks ago media were widely promoting 98% as the ratio of unvaccinated Covid-19 patients to vaccinated patients in hospitals. This item today reports that breakthrough infections account for about 15% to 20% of hospitalizations. That’s a big difference, a shift of almost 20%.
The likely explanation is that the earlier percentage was just a guesstimate, whereas the newer percentages are data-driven.
I’m not inclined to speculate on what the data is telling us, except to note that you can’t really blame hospital capacity shortages on the unvaccinated with so many vaccinated patients taking up beds.
The breakthrough infection hospitalization rate bears watching.
