Summary: I walk you through the proposed shift away from universal newborn hepatitis B vaccination at birth, why it matters, what the evidence shows, and how parents can make a calm, informed choice—without reigniting every vaccine debate.

Episode highlights

I explain why hepatitis B is uniquely risky for babies: if infected early, up to 90% develop lifelong infection with later risks of cirrhosis and liver cancer. I also clarify that exposures aren’t only from mom at delivery—household contact and tiny blood exposures matter.
We review what happened after the U.S. moved to a universal newborn dose in 1991: childhood hepatitis B plunged dramatically, with no new safety concerns emerging from hundreds of millions of doses.
I outline the new proposal: keep the birth dose for babies of mothers who are positive or whose status is unknown; consider delaying to two months when mom tests negative—via shared decision-making with the pediatrician.
I describe why many pediatric and public health experts still favor the birth dose: it protects against documentation errors and early exposures, and it avoids added “friction” that can reduce on-time vaccination.
I address autism concerns with empathy and evidence: large studies and reviews have not found a link between vaccines—including hepatitis B—and autism.
My take: I would keep the universal birth dose because it’s safe, simple, and highly effective. But if parents delay, they should commit to the 2-month visit and rely on their clinician—not social media.

Key takeaways

The risk window is small but meaningful. Early-life infection can have lifelong consequences; the birth dose is a safety net.
Process vs. evidence matters. Policy shifts should be driven by strong data, not ideology or committee turnover.
If you delay, have a plan. Put the two-month appointment on the calendar now and follow through.
Know your status. Make sure maternal hepatitis B testing is done and documented correctly.
