This is what hepatitis B vaccination is about.

When I was a medical student 45 years ago, I clerked in a 13 year old girl with deep jaundice and an abdominal mass. She was Hepatitis B positive. That had led to a primary liver tumour. In a 13-year-old. She was dead within the month. Avoidable with vaccination.

The CDC has endorsed ACIP’s decision of revoking universal access in USA to hepatitis B vaccines at birth. The policy had been in place for 34y and was changed despite no new evidence emerging of any risk of vaccination. #HealthPolicy 🧵

We are supposed to believe that FDA paused and removed the J&J vaccine immediately after 6 cases of clotting, but they hid 10 kids dying from the mRNA vaccines until Prasad and Hoeg, who were always antivaxx, revealed the truth.

Checks out.

Engagement-based #algorithms amplify intergroup hostility + moral-emotional content, leading it to be overrepresented in your feed

This leads us to falsely perceive that people want to see this kind of content and share more of it.
