The vast majority of “flu deaths” are actually pneumonia deaths. Anyone over 70 or 80 who is hospitalized has a significant chance of developing pneumonia, and it’s quite possible, or even likely, that many cases of “Hospital Acquired Pneumonia” are blamed on the flu, and cause of death listed as “Influenza Related Pneumonia”. It covers up a significant source of hospital CAUSED deaths and probably avoids significant liability.
IIRC the Obama admin ordered a stop to Swine flu tests in 2009 and then declared all possible deaths to be due to it—with none of it proven.
