This is Senator Ron Johnson's letter to Defense Secretary Austin about the original data. https://www.ronjohnson.senate.gov/2022/2/sen-johnson-to-secretary-austin-has-dod-seen-an-increase-in-medical-diagnoses-among-military-personnel
Soon after this data was made public the Dept of Defense deleted all the original data from the years prior to 2021 and replaced it with new data with much higher numbers that hid the 2021 spikes.
This is a massive cover up of diseases and injuries in the US Military that began in 2021. Read more about that coverup here:
You already have the answer. The data shows the effects of the vaccine. The DoD is editing the data to normalize the reported numbers between 2020 and 2021 so that the differences aren't so dramatic when compared to other years. And the MSM is ignoring it. That tells you the data illustrates the effects of the vaccine.
If it showed the effects of covid then it would be a justification for vaccination. There would be no need to edit the data and it would be paraded around every MSM talk show for the next few weeks discussed ad nauseum.
