State secrets or arrogance?

According to the CDC myocarditis after COVID vaccination is rare.

Cases of myocarditis and pericarditis have rarely been observed after COVID-19 vaccination in the United States

The CDC knows that myocarditis is rare because they have a 148 page study that tells them so.  We will need to take the CDC at their word because the study is a little difficult to read.  The difficulty does not lie in the technical jargon.  The study is difficult to read because before releasing it the CDC redacted every single word in the study.

Documents get redacted to protect identities, trade secrets, or national secrets.  Do you think the entire document was just names and addresses of people?  Surely there were at least a few words in the document that discussed myocarditis.  Or are we to believe that myocarditis itself is some sort of trade secret?  I sincerely doubt that the report contained identity information or trade secrets.  I do not doubt that the report contained national secrets.

National secrets typically are intelligence or weapons capabilities.  Casualty and mortality estimates of a secret bioweapon would certainly be a national secret.  By redacting every single word was the CDC accidentally disclosing that the COVID vaccine is a bioweapon?  Or is it just a bunch of arrogant overpaid government employees raising their middle finger to the people who pay their salaries?

Either way it is not a good look.
