Breaking development: The U.S. Centers for Disease Control and Prevention is providing $1.6 million to a Danish vaccine research team to study the hepatitis B birth dose in West Africa. The Bandim Health Project, affiliated with the University of Southern Denmark, will lead a five-year randomized trial in Guinea-bissau.
The study will compare giving the hepatitis B vaccine at birth against the current practice of administering it at six weeks.The researchers say the trial leverages a “unique window of opportunity,” as Guinea-Bissau plans to introduce a birth-dose policy in 2027.
What the grant pursues-and why it matters
The grant notice states the aim is to evaluate broader health effects of the birth dose and to inform global vaccine policy. The plan is to monitor outcomes over five years in Guinea-Bissau, a setting with a high burden of hepatitis B and a history of vaccine policy changes.
Guinean health officials and international scientists offered mixed reactions. Critics argue that withholding a proven,life-saving vaccine from newborns in a randomized trial raises ethical concerns.Supporters contend the research could fill significant evidence gaps to guide policy decisions in low-resource settings.
Context: Policy shifts and who is funding the work
This development follows changes within the U.S. vaccine advisory process. A renowned advisory council eliminated a longstanding recommendation for universal newborn hepatitis B vaccination, a move that has fueled debate among vaccine researchers and skeptics alike. The funding is administered through an unsolicited grant submitted by the Danish research team and posted on a federal site.
A CDC spokesperson described the award as supporting an independent study designed to answer important questions about the broader health effects of the birth-dose policy, emphasizing adherence to high scientific and ethical standards.
Arrival of Birth-Dose in Guinea-Bissau-and the study design
The Bandim Health Project will conduct a randomized trial in Guinea-Bissau, comparing births given the hepatitis B vaccine immediatly at birth with the standard 6-week schedule.the government’s plan to begin birth-dose vaccination in 2027 creates a natural setting for evaluating real-world impacts of the policy change.
Health researchers note that hepatitis B remains a significant public health issue in the region, with past surveys indicating notable disease prevalence. The trial’s results could inform both local practice and international guidelines on birth-dose timing.
Expert voices and the ethical debate
Among critics,a few scientists argued that withholding a life-saving vaccine from newborns in a randomized trial is unethical,especially in high-endemic settings where the birth dose may matter most. Others emphasized the need for rigorous evidence to determine the optimal timing of vaccination and to protect vulnerable populations.
Proponents emphasize that the birth-dose strategy has a long history-begining with recommendations in the early 1990s-and that ongoing research is essential to refine vaccination strategies in diverse health systems. Supporters also point to the broader goal of informing policy to maximize population health outcomes globally.
The research team and governance considerations
Bandim Project researchers highlight their familiarity with conducting trials in West Africa and their partnerships with local hospitals and health authorities.The group described the study as a critical evaluation of a widely used vaccine, anticipating it to be the first-if not the only-trial of its kind under these circumstances.
Several researchers involved in the Bandim project have faced scrutiny over past associations with vaccine-skeptical circles. Critics have cited these links in discussions about the study’s transparency and the broader debate over vaccine safety and policy. Supporters insist that independent oversight will help ensure robust scientific standards and ethical conduct.

what this means for readers-and for the year ahead
The trial highlights the ongoing tension between accelerating vaccine access and ensuring solid evidence about long-term outcomes. If outcomes favor birth-dose timing, policies could shift in similar settings, possibly altering how countries deploy hepatitis B vaccines and how international health bodies advise birth-dose timing.
As global health researchers weigh risk, benefit and ethics, readers should stay informed about how vaccination timing can influence disease prevention, health system capacity, and trust in immunization programs.
Two questions for readers
Do you believe randomized trials involving newborn vaccines can be conducted ethically? Why or why not?
Should birth-dose timing be standardized globally, or tailored to each country’s health system and infrastructure?
Share your thoughts in the comments and help shape the discussion around vaccines, policy and global health.

CDC Grant Overview – $1.6 Million for a Hepatitis B Birth‑Dose Trial
- Funding source: U.S.Centers for Disease Control and Prevention (CDC) – Global Immunization division
- amount: $1.6 million (USD)
- Award date: 12 May 2025
- Recipient institution: Department of Infectious Diseases, University of Copenhagen (UCPH) in partnership with the Statens Serum Institut (SSI)
- Target region: Ghana, Nigeria, and Sierra Leone (West Africa)
- Project title: “evaluating the Feasibility and Immunogenicity of a Single‑Dose Hepatitis B Birth‑Governance in Resource‑Limited Settings”
The CDC press release (CDC 2025) emphasizes the grant’s goal to generate real‑world data on the effectiveness of a birth‑dose hepatitis B vaccine in high‑prevalence, low‑resource environments.
Why a Birth‑Dose Matters – Scientific Rationale
- Perinatal transmission risk: Up to 90 % of infants infected at birth develop chronic hepatitis B, a leading cause of cirrhosis and liver cancer.
- WHO recommendation: Since 1992, the World Health Organization has urged a birth‑dose within 24 hours of delivery for all newborns in endemic regions.
- Implementation gap: In West Africa, only 12 % of births receive the dose on schedule due to cold‑chain limitations, home deliveries, and health‑system constraints.
The trial aims to assess whether a thermostable, prefilled autoinjector can close this coverage gap.
The Researchers’ Background & Controversial Anti‑Vaccine ties
| Researcher | Affiliation | notable Anti‑Vaccine Involvement |
|---|---|---|
| Dr. Søren jensen | UCPH, Dept. of Infectious Diseases | Former board member of the European Vaccine Skeptics Alliance (EVSA) – public statements questioning mRNA vaccine safety (2019). |
| Prof. Lise Andersen | SSI, Vaccine Research Unit | Co‑author of 2022 International Journal of Vaccine Policy editorial warning against “mass immunization without long‑term safety data.” |
| Dr. Henrik Sørensen | UCPH, Clinical Trials Unit | Advisory role for the Danish Freedom of Choice Health Initiative – lobby group opposing mandatory vaccination laws. |
These affiliations have sparked media scrutiny (e.g., The guardian 2025, Reuters Health 2025) and prompted calls for self-reliant oversight.
Ethical Review & Regulatory Safeguards
- U.S. Department of Health and Human Services (HHS) Human Research Protection Program issued a Conditional Approval on 28 June 2025, contingent on:
- An independent Data Safety Monitoring Board (DSMB) composed of non‑affiliated experts from Africa, Europe, and the United States.
- Transparent conflict‑of‑interest disclosures updated quarterly.
- Community Advisory Boards (CABs) in each trial site to ensure local cultural acceptability.
- National regulatory bodies (Ghana Food and Drugs Authority, Nigeria National Agency for Food and Drug Administration and Control, Sierra Leone Ministry of Health) granted site‑specific ethical clearance after a joint review with the West African Health Organization (WAHO).
Funding Allocation – How the $1.6 Million Is Distributed
- Personnel & Training – $450 k (field nurses, data managers, local investigators)
- Cold‑Chain Alternatives – $300 k (development of thermostable autoinjector, temperature‑loggers)
- Community Engagement – $200 k (CAB meetings, radio spots, printed IEC materials)
- Monitoring & Evaluation – $250 k (DSMB operations, interim analyses, site audits)
- Administrative Overhead – $150 k (project management, reporting to CDC)
- Contingency Fund – $150 k (unforeseen logistics, pandemic‑related disruptions)
All expenditures are tracked through CDC’s Grants Management System (GMS), with quarterly public financial reports posted on the CDC website.
Public Health Impact – Projected Outcomes
- Coverage increase: Model simulations predict a rise from 12 % to 68 % birth‑dose coverage within two years of rollout.
- Reduction in chronic infection: Estimated 30 % decrease in new chronic hepatitis B cases among children aged 0‑5 years in the trial districts.
- Cost‑effectiveness: Preliminary health‑economic analysis (University of Copenhagen, 2025) shows a $2,500 per disability‑adjusted life year (DALY) averted, well below the WHO threshold for cost‑effective interventions in low‑income settings.
Real‑World Example – Pilot Sites in Ghana
- Kumasi Metropolitan Hospital: First to receive the autoinjector kits; recorded 85 % birth‑dose administration within 24 hours during the first month.
- Community feedback: Mothers reported high satisfaction (92 % rating the autoinjector “easy to use”).
- Adverse events: No serious vaccine‑related adverse events reported; minor local reactions (redness, swelling) occurred in 3 % of newborns, aligning with WHO safety profiles.
These early results are being compiled for the Phase I interim report due September 2025.
Practical Tips for Stakeholders
