I Am Skeptical of Causality

 Sen. Johnson's letter to Secretary of Defense claims the following diseases in military personnel increased in 2021 over previous years:

 Hypertension – 2,181% increase 

 Diseases of the nervous system – 1,048% increase 

 Malignant neoplasms of esophagus – 894% increase 

 Multiple sclerosis – 680% increase 

 Malignant neoplasms of digestive organs – 624% increase 

 Guillain-Barre syndrome – 551% increase 

 Breast cancer – 487% increase 

 Demyelinating – 487% increase 

 Malignant neoplasms of thyroid and other endocrine glands – 474% increase

 Female infertility – 472% increase 

 Pulmonary embolism – 468% increase 

 Migraines – 452% increase 

 Ovarian dysfunction – 437% increase 

 Testicular cancer – 369% increase 

 Tachycardia – 302% increase  

Now some of these might plausibly be blamed on COVID vaccinations in the last year: tachycardia, multiple sclerosis.  But many of these are cancers, which seldom develop enough to be detectable in less than a year.  Claims like this make legitimate claims look ridiculous.
