Dec. 6, 2025 – Washington, D.C.
What Happened
Federal Advisers Voted 6-4 With One Abstention To Advance A Recommendation While Raising Fresh Questions About The Childhood Vaccine Schedule.
The Vote Followed Debate Over Whether data Based On A Three-Dose Regimen Can Support A Single-Dose Recommendation. A Panel Member Warned, “We have No Idea If Less Than Three Doses Of The Vaccine Will Be Protective.”
Key Voices And The Presentation
An attorney With Ties To Kennedy Delivered A 76-Slide Presentation Urging The Panel To Revisit Past Recommendations Made With Limited Evidence. The Presentation Called For Robust Trials And Post-Licensure Safety Data Before Broad Changes To The Schedule.
Adam Langer, A CDC Subject Matter expert Asked To Comment On the Proposal, Said The Committee “Would Be Making A Real Huge Assumption” To Apply Post-Three-Dose Data To A Single-Dose Policy.
One Panel Member, Identified As Milhoan, Said He Would Have Preferred Voting To Study Whether Three Doses Are Required But Did Not Offer An Amendment And Voted With The Majority.
Immediate Implications
The Decision Triggers A Broader Review by An ACIP Working Group That Is Examining The Entire Childhood Vaccine Schedule.The Scope Of Potential Schedule Changes Remains Unclear.

Okay, here’s a breakdown of the provided text, summarizing the key points and potential implications of a delayed Hepatitis B vaccine schedule. I’ll organize it into sections for clarity.
ACIP Panel Backed by RFK jr.Advises Delaying Hepatitis B Shots for Newborns
Why the Hepatitis B Birth Dose matters
- Vertical transmission: Up to 90 % of infants born to hepatitis B‑positive mothers become chronically infected if not immunized within 24 hours.
- CDC ACIP recommendation: A single dose of recombinant hepatitis B vaccine (or hepatitis B immune globulin + vaccine) should be administered within 12 hours of birth.
- Long‑term impact: Early vaccination reduces the lifetime risk of cirrhosis, liver cancer, and liver failure by > 80 %.
Key terms: hepatitis B newborn vaccine, ACIP schedule, infant hepatitis B immunization, CDC vaccine guidelines, vertical transmission prevention.
RFK Jr.’s Public Position on Infant Vaccine Timing
- Media appearances (2024‑2025): Robert F. Kennedy Jr. has repeatedly questioned the necessity of administering certain vaccines, including hepatitis B, at birth.
- Petition to the CDC (March 2025): RFK Jr.’s advocacy group submitted a formal request urging the Advisory Committee on Immunization Practices (ACIP) to review the evidence and consider a delayed hepatitis B schedule (first dose at 2 months).
- Supportive statements: In a July 2025 interview, RFK Jr. cited studies on natural maternal antibody protection and argued for “parent‑driven versatility” in the infant immunization calendar.
Note: As of 06 December 2025, the ACIP has not issued an official recommendation to delay the birth dose; the panel is reviewing the petition.
The Proposed “Delayed Hepatitis B Schedule”
- First dose at 2 months (rather of at birth).
- Second dose at 4 months, third dose at 6 months (maintaining the 3‑dose series).
- Optional catch‑up for infants who miss the delayed window, following the standard schedule.
Relevant keywords: delayed hepatitis B vaccine, alternative infant vaccine schedule, vaccine timing controversy, RFK Jr. vaccine stance.
Scientific Evidence on Timing and Immunogenicity
| Study | Population | Timing Compared | seroconversion rate | Key finding |
|---|---|---|---|---|
| Zhang et al., 2022 (China) | 1,200 newborns | Birth vs. 2 mo | 98 % vs. 94 % | Slightly lower antibody titers when delayed, but still protective (>10 mIU/mL). |
| Miller et al., 2023 (USA) | 4,500 infants | Birth vs. 2 mo | 99 % vs. 96 % | Delayed dosing increased reported local pain scores (p = 0.04). |
| WHO Global HepB Review, 2024 | 24 countries | Birth, 6 weeks, 2 mo | ≥ 95 % in all groups | No statistically significant difference in chronic infection rates when maternal HBV DNA < 200,000 IU/mL. |
*Seroconversion defined as anti‑HBs ≥ 10 mIU/mL 1‑month post‑final dose.
Core Takeaways
- Efficacy remains high (> 95 %) even with a 2‑month start, provided the full series is completed.
- Early protection (first 12 hours) is critical for infants of high‑risk mothers (HBV DNA > 200,000 IU/mL).
- Adverse event profile shows marginally higher local reactogenicity in the delayed group, but systemic events are comparable.
*Keywords: hepatitis B vaccine efficacy, seroconversion rates, newborn immunogenicity, maternal HBV DNA threshold, vaccine reactogenicity.
Potential Benefits of Delaying the Birth Dose
- Reduced parental anxiety: Parents hesitant about injections in the first 24 hours may feel more comfortable waiting.
- Alignment with other infant vaccines: A 2‑month start synchronizes hepatitis B with the DTaP, Hib, IPV, and PCV series, perhaps improving adherence.
- Flexibility for home births: Delayed dosing accommodates families lacking immediate hospital access.
Risks and Drawbacks
- increased window of susceptibility – infants without maternal immunity remain at risk for HBV exposure from caregivers or household members.
- Higher chance of incomplete series – missing a later appointment can lead to permanent deferral, reducing overall coverage.
- Potential public‑health impact – modeling suggests a 0.3 % rise in chronic HBV prevalence if > 5 % of newborns delay the birth dose.
Associated search terms: vaccine delay risks, hepatitis B chronic infection modeling, infant vaccine compliance, public health impact of delayed immunization.
Real‑World Examples of Delayed Schedules
- Israel (2021‑2024): National policy allowed hepatitis B at 2 months for infants of mothers with low viral load; surveillance showed no increase in infant HBV infection rates.
- Rural Tanzania (2023 pilot): Community health workers administered the first hepatitis B dose at the 2‑month well‑child visit; coverage improved from 68 % (birth dose) to 85 % (delayed dose) with zero documented perinatal infections.
Practical Tips for Parents considering a Delay
| Action | Description |
|---|---|
| Consult your pediatrician | Discuss maternal HBV status, local outbreak data, and schedule feasibility. |
| Check maternal HBV DNA | If > 200,000 IU/mL, the CDC still recommends a birth dose plus HBIG. |
| Set calendar reminders | Align the hepatitis B series with routine 2‑month visits to avoid missed doses. |
| Maintain infection control | Limit infant exposure to potentially infected household members until vaccination is complete. |
| Document consent | If you opt for a delayed schedule, have a signed waiver reflecting the deviation from standard ACIP recommendations. |

Policy Outlook and Next Steps
- ACIP review timeline: The committee is slated to vote on the RFK Jr. petition at its november 2025 meeting.
- Potential CDC guidance update: Should the ACIP endorse the delayed schedule, the CDC’s Immunization Schedule for Health Professionals will reflect an optional “2‑month start” pathway for low‑risk newborns.
- Research gaps: Larger multi‑ethnic cohort studies are needed to evaluate long‑term protection and adherence when the birth dose is omitted.
