The day I stopped trusting the CDC flu shot numbers after a scare in Atlanta back in 2019
I was at a health fair in Atlanta getting my yearly flu shot, and this volunteer nurse let it slip that the effectiveness rate they post is based on like 500 people total, not millions like they claim. Then she caught herself and got real quiet. I went home and looked up the actual studies, and yeah, the sample sizes are tiny for something that affects the whole country. Has anyone else dug into the actual data behind these public health numbers?
