YouTube Description
as posted by the channelOn this, our 303rd Evolutionary Lens livestream, we discuss the recommendation to stop vaccinating newborns against Hepatitis B, as just handed down by ACIP (Advisory Committee on Immunization Practices) for the CDC. Why were newborns whose mothers do not have Hep B, being vaccinated against a disease that is contracted through sexual activity and dirty needles? We discuss claims of “safe and effective,” risk stratification, the childhood vaccine schedule, and what “individual-based decision-making” will mean for parents and doctors. Then, new research: tattoo ink induces inflammation in lymph nodes, and changes the immune response to vaccination. Finally: an homage to Tom Stoppard, playwright extraordinaire, author of Rosencrantz and Guildenstern are Dead, Arcadia, and so much more. RIP.
