OP said hospitalizations has reduced to 1/6th.

Unless you can prove to me that 5 of every 6 doctors and nurses have quite due to vaccin mandates i think we are in better shapes as before

(even ignoring that anti-vaxxers in hospitals act as superspreaders)

Covid hospitalizations were reduced to 1/6th. Are those the only kinds of hospitalizations?

No. But that's not the key question. The key question is: Did this reduction reduce the hospital requirement forecasts such that hospitals have free beds and can handle sudden and big accidents? An aircraft crash, a derailed train, a wave of food poisonings? And that is now the case, since the vaccines protect so well against severe effects.

No, but they are the only ones with high hospital demand currently being driven by an explosive contagious vector.
