Earlier this month, the gold-standard Cleveland Clinic published a shocking study titled, “Effectiveness of the Influenza Vaccine During the 2024-2025 Respiratory Viral Season: A Prospective Cohort Study.” In short, the Clinic found that last year’s flu vaccine was at least as effective at preventing the potentially deadly disease than using Himalayan prayer beads or nailing a dead raccoon over your front door.
Haha, I’m just kidding. According to the study of some 53,000 healthcare professionals, dead raccoons and prayer beads work better than the flu vaccine. The Clinic found that, after about 90 days following the injections —well after any FDA-required postmarketing trials stop looking— staff who got the shots became increasingly more likely to get the flu than their unjabbed coworkers.
In technical terms, the Clinic’s researchers discovered the flu vaccine had a negative efficacy of -27%.
Now look, dummies, I know what you’re thinking. You’re thinking I’ll just stick with the raccoons. But that’s because you aren’t a $cientist. Unlike you, those profit-seeking professionals know how to say “correlation does not prove causation.” Just because thousands of healthcare workers were more likely to come down with the flu after getting the shots doesn’t prove the shots caused it. It could be anything, like witches. Or anti-vaxxers. Either one.
You really need to learn this lesson. Correlation definitely does not prove causation … unless it tends to show that vaccines work. Then it’s Katy, bar the door.
