It is an entirely incorrect argument to suggest that the number of fully vaccinated people hospitalized or reinfected reflects what is being suggested. If you do not know the pre-existing condition of the individual you have bad data, or perhaps you are using data badly. It is clear that higher risk people, the elderly, the ill, the immunosuppressed, the obese, cancer survivors etc have a much higher rate of being vaccinated. They also have a much higher risk of becoming ill with infection.
I have not seen any
breakdown of the demographic and pre-existing conditions of vaccine recipients who have been ill. Sec of State Powell is an excellent example of why you need full data to make useful conclusions. Yes he was vaccinated, and he got Covid and died.
Certain media made a big deal out of that limited data. What is much more important is that he was undergoing treatment for multiple myeloma which made him very immune suppressed and may have meant he did not even mount much of a response to being vaccinated.
If only everyone around him had always masked and all been fully vaccinated that would have lessened but not eliminated his risk.
Another confounder in the data is that those who are the furthest out from their shots, those vaccinated first, not only may be loosing some immune protection but very importantly they are also the group who may have had poor vaccine responses and are more susceptible to disease... that's why they were first up for shots.
