Most of these people don't think that it IS a problem: "It's just the flu", etc. And the unvaxxed are killing not just themselves, but the rest of us (when we can't get hospital beds), too.
For example, Duke University Hospital has 957 beds. Right at this moment, it has 305 COVID patients. Of those 305, 208 are unvaxxed. Out of those 305, 59 are in the ICU. Of those 59, 47 are unvaxxed. Of those 59, 35 are on a ventilator. Of those 35, 30 are unvaxxed. 3 ICU patients are on ECMO (Extracorporeal Membranous Oxygenation - basically, an artificial lung. COVID patients who are on ECMO are almost guaranteed dead; you're just prolonging the inevitable). Those 3 are unvaxxed. 305/957 = 32% of the hospital's bed capacity is being utilized by COVID patients. 208/305 = 68% of those patients are unvaxxed. 80% of ICU patients are unvaxxed. 86% of the ventilator patients are unvaxxed. These numbers are from THIS MORNING. And that's just at Duke. Other hospitals in the area such as UNC, Rex, Wake Med, aren't any better. Nationally, it's just as bad.
These numbers are unsustainable, and it's just going to get worse as the Omicron wave continues, even if it's on its way down; that's because hospitalizations and deaths lag infections. The beds being taken up by the unvaxxed are causing those with needed surgeries (like critical cancer surgeries) not to be able to get them; those surgeries have been cancelled due to lack of bed space and for fear of infecting those patients. Right now, only emergency surgeries are being performed.
