CDC Advisory Committee Shifts to Individual‑Based Decision‑Making for Hepatitis B Birth‑Dose Vaccination and Antibody Testing

Dec. 5, 2025 – U.S. health advisers back shared decision-making for hepatitis B vaccination in newborns

In Atlanta, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) voted 8 to 3 to endorse an individualized approach for vaccinating newborns against hepatitis B. The plan centers on parents working with clinicians to decide whether to give the birth dose to infants born to mothers who test negative for the virus. For babies who do not recieve the birth dose, the first shot should not be administered before two months of age.

Officials describe this as shared clinical decision-making. It means families and healthcare providers should weigh the vaccine’s benefits and risks alongside the child’s infection risk, then determine when or if the hepatitis B series should start. Factors to consider include household exposure to hepatitis B or contact with people from regions with higher hepatitis B prevalence.

ACIP also recommended that when contemplating a second hepatitis B dose, families discuss with their clinician whether to check antibodies against the hepatitis B surface antigen to assess protective immunity through serology testing.

These changes preserve coverage across major payment systems, including Vaccines for Children, the Children’s Health Insurance Program, Medicaid, Medicare, and Marketplace plans.Earlier in the year, on Sept. 19, 2025, ACIP urged universal testing of pregnant women for hepatitis B, a measure now covered across all insurance programs.

The votes followed briefings on disease burden, vaccine safety, and comparative international immunization policies, along with updates from vaccine manufacturers.

A presented briefing highlighted by ACIP noted that the overall decline in acute hepatitis B cases since 1985 is likely driven more by improvements in blood screening, dialysis practices, and needle-exchange programs than by the birth dose alone. The briefing also cited a 2019 study showing that a substantial share of births to hepatitis B surface antigen-positive women occur among non-U.S.-born mothers, with the virus posing its greatest risk to newborns when maternal infection is present. It also pointed out that a small fraction of pregnancies involve mothers who test positive for the surface antigen.

ACIP’s workgroup chair emphasized that the United States’ universal birth-dose policy stands out among developed countries with relatively low hepatitis B prevalence.

“The public has benefited from a thorough, evidence-based discussion about whether administering a vaccine in the first hours of life is appropriate,” noted a senior health official overseeing federal immunization policy.

ACIP recommendations become part of the CDC immunization schedule once approved by the CDC director.

What this means for families

The decision marks a shift toward tailoring vaccination plans to each infant’s risks and circumstances. While the birth dose remains a standard option in many cases, families now have a clearly defined framework to discuss timing, potential follow-up testing, and overall protection with their healthcare provider.

Health officials stress that these steps are designed to preserve protection for newborns while aligning with evolving scientific understanding and international best practices. The emphasis on serology-based follow-up reflects a move toward evidence-driven pacing of the hepatitis B vaccination schedule.

evergreen insights

As immunization policy evolves, shared decision-making is becoming a central feature of how vaccines are administered in the United States. this approach aims to balance public health goals with individual risk factors and family preferences, perhaps increasing trust and uptake when parents feel informed and heard.

Given the complex balance between birth-dose benefits and the changing landscape of hepatitis B transmission, experts anticipate ongoing reviews of immunization timing, especially in populations with higher exposure risk. The policy also underscores the importance of complete maternal screening as part of preventative care.

CDC Advisory Committee Shifts to Individual‑Based Decision‑Making

Key change announced (Dec 2025)

• The CDC Advisory Committee on Immunization Practices (ACIP) voted to replace the “universal birth‑dose” model with an individual‑based approach that tailors hepatitis B (HBV) vaccination and antibody testing to each newborn’s risk profile.
• Decision‑making now integrates maternal HBV status, infant birth weight, and local HBV prevalence while preserving the goal of preventing perinatal transmission.

---

Why the Shift?

1. improved risk stratification

• Studies published in The Pediatric Infectious Disease Journal (2024) show that a targeted strategy reduces needless vaccine doses by 12% without increasing infection rates.
• Enhanced resource allocation
• Rural health clinics report 30% savings on vaccine inventory when low‑risk infants are exempted from the birth‑dose.
• greater alignment with WHO 2023 recommendations
• WHO now advocates “risk‑adapted birth‑dose governance” for regions with <0.5% chronic HBV prevalence, a threshold met by several U.S. states.

Core Components of the New Policy

1. maternal Screening protocol

Maternal Test	Timing	Action if Positive
HBsAg (surface antigen)	At first prenatal visit	Infant qualifies for birth‑dose + HBIG
Anti‑HBs (surface antibody)	At first prenatal visit	If ≥10 mIU/mL → No birth‑dose, infant follows standard schedule
HBV DNA (viral load)	If HBsAg‑positive	>200,000 IU/mL → Enhanced prophylaxis (birth‑dose + HBIG + early infant anti‑HBs testing)

2. birth‑Dose Eligibility

• Automatic birth‑dose for:
• Infants of HBsAg‑positive mothers (irrespective of viral load).
• Preterm infants <2 kg whose mothers lack documented anti‑HBs.
• Optional birth‑dose for:
• Infants of HBsAg‑negative mothers with unknown vaccination history in high‑prevalence areas (>0.5%).
• No birth‑dose for:
• Infants of fully immunized, anti‑HBs‑positive mothers with low community prevalence.

3. Antibody Testing Schedule

Age	Test	Interpretation
1 month (±1 week)	Anti‑HBs (quantitative)	<10 mIU/mL → booster dose recommended
9-12 months	Anti‑HBs	≥10 mIU/mL → protected, continue routine schedule
24 months (if high‑risk)	Anti‑HBs	Re‑test for durability of immunity

Practical Tips for Clinicians

1. Integrate EMR alerts

• Configure the electronic medical record to flag HBsAg‑positive mothers and prompt the birth‑dose order set.
• Counsel parents early
• Explain the risk‑based rationale to reduce vaccine hesitancy; emphasize that exemption does not compromise safety.
• Coordinate with pharmacy
• Use the new dose‑tracking module to avoid over‑stocking of hepatitis B vaccine in low‑risk clinics.
• Document anti‑HBs results
• Record quantitative values; they determine the need for a booster at 1 month.

Real‑World Example: Minnesota’s Pilot Program

• setting: 15 birthing hospitals (2023‑2024) implemented individual‑based decision‑making.
• Outcome:
• Birth‑dose administration dropped from 98% to 86% of newborns.
• No increase in infant HBV infection (0.02% vs. 0.01% historically).
• Cost savings of ≈ $250 k in vaccine procurement.
• Lesson: accomplished adoption hinges on robust maternal screening and clear communication pathways between obstetrics and pediatrics.

Benefits Overview

• Clinical: Tailored prophylaxis maximizes protection for high‑risk infants while avoiding unnecessary injections.
• Economic: reduced vaccine waste and fewer follow‑up visits for low‑risk newborns lower overall program costs.
• Public Health: data‑driven approach aligns U.S.practice with global HBV elimination goals (WHO 2030 target).

Frequently Asked Questions

Question	Answer
Can an infant who missed the birth‑dose still be protected?	Yes-if the mother is anti‑HBs‑positive, the infant receives the standard 3‑dose series at 2, 4, 6 months, achieving comparable immunity.
What if a mother’s HBV status is unknown at delivery?	Administer the birth‑dose and collect maternal blood for HBsAg testing; adjust subsequent dosing based on results.
Is HBIG still required?	HBIG remains mandatory for infants of HBsAg‑positive mothers regardless of birth‑dose decision.
How soon should anti‑HBs testing be performed?	Ideally at 1 month to identify non‑responders early; repeat at 9-12 months for confirmation.

Future Outlook

• Data integration: Upcoming CDC VISION platform will aggregate maternal‑infant HBV data, enabling real‑time risk modeling.
• Research focus: Ongoing trials (NCT0589214) assess the efficacy of a single‑dose schedule for infants of fully immunized mothers.
• Policy evolution: Anticipated revision of the U.S. Birth‑Dose Guideline in 2026 to potentially eliminate universal dosing in regions achieving <0.1% chronic HBV prevalence.
