COVID vaxxx made you ill ? no Insurance will pay out

Very sick and paralyzed on lower half of her body after the Johnson & Johnson vaccine. Her insurance, despite recommending hospitalization, will not cover the expenses. Are these the kind of problems worth dealing with, because of a supposed virus with more than 99% survival rate for her age group? Or any age group, since the survival rate is 95% for those over 90 yrs old. That said we’re only going by the numbers given by the WHO and CDC and know Coronavirus is just a flu strain. Why do this to yourself?
