What I am consistently observing is the absence of actual broken down data to support the ongoing claim that vaccination prevents hospitalization. Claims such as "the hospitalized are mainly unvaccinated or not completely vaccinated" seem to be textbook sophisms aiming to influence the reader into correlating vaccination with absence of hospitalization.
For example, if a "complete vaccination" status is stipulated to be 4 shots, someone with 3 shots is deemed "not completely vaccinated". So if you have 20 hospitalized people, of which 2 have had zero shots and 10 have had three shots, mathematically the claim "the hospitalized are mainly unvaccinated or not completely vaccinated" is correct although it is a fallacy. You would need 11 people with zero shots for this claim to be dialectically valid, and I sincerely doubt that is the case, otherwise they would for sure tell us.
