Wenn ansonsten Gesunde ob C im Krankenhaus landen, könnte die Ursache in einer Schwächung des Immunsystems aufgrund Impfungen in der Vergangenheit liegen.
Muss nicht sein, aber kann... daher ungeklärt, wie Du selbst sagst.
Vielleicht auch psychisch bedingt, wer weiß? Evtl. weil durch mediales Fearporn die Psyche geschädigt wurde...

BNT162b2 vaccine breakthrough: clinical characteristics of 152 fully-vaccinated hospitalized COVID-19 patients in Israel

"Results
152 patients were included, accounting for half of hospitalized fully-vaccinated patients in Israel. Poor outcome was noted in 38 patients and mortality rate reached 22% (34/152). Notable, the cohort was characterized by a high rate of comorbidities predisposing to severe COVID-19, including hypertension (108, 71%), diabetes (73, 48%), CHF (41, 27%), chronic kidney and lung diseases (37, 24% each), dementia (29, 19%), and cancer (36, 24%), and only 6 (%) had no comorbidities. Sixty (40%) of the patients were immunocompromised. Higher SARS-CoV-2 viral-load was associated with a significant risk for poor outcome. Risk also appeared higher in patients receiving anti-CD20 treatment and in patients with low titers of anti-spike IgG, but these differences did not reach statistical significance."
