Episode notes
Shift In Hepatitis B Birth-Dose Policy
- The ACIP voted to shift hepatitis B birth-dose decisions to parent-provider discussions when the birthing parent tests negative.
- Experts warn this change could erode decades of progress in virtually eliminating childhood hepatitis B in the U.S.
Track Policy Changes And Access Risks
- Follow developments as ACIP recommendations go to the acting CDC director who typically adopts them.
- Monitor coverage and access implications because new consultation requirements could weaken vaccine uptake.
Potential FDA Changes Could Limit Access
- The FDA is reportedly reconsidering stricter vaccine rules for pregnant people and co-administration of flu and COVID shots.
- Critics say such changes could raise costs and reduce childhood vaccination accessibility without clear supporting evidence.
