Guinea-Bissau Police Seize Vaccines as CDC-Funded Trial on Newborns Is Halted

Key points

• Guinea-Bissau police raided the offices of the Bandim Health Project on Monday, seizing a batch of hepatitis B vaccines intended for a newborn trial.
• The trial was funded by $1.6 million from the US CDC and $1.6 million from private partners, including the Pershing Square Foundation.
• The study, led by Danish researchers Peter Aaby and Christine Stabell Benn, hypothesized that giving the hepatitis B vaccine alongside the BCG vaccine might dampen the BCG's potential mortality benefits.
• Health Minister Quinhin Nantote confirmed the government has not authorized the trial, stating that research involving children must comply with national ethical principles.
• The CDC and private funders have not yet confirmed whether the appropriated funds will be redirected to universal vaccination efforts as recommended by the WHO.

Background

This development follows a broader pattern of controversy surrounding HHS Secretary Robert F. Kennedy Jr.’s administration and its support for anti-vaccine research. In September 2026, Kennedy Jr. validated anti-vaccine agendas at the Children’s Health Defense conference, citing vaccine safety concerns despite a worsening measles outbreak in the US. The current trial aligns with the administration's skepticism of standard vaccination protocols, which critics argue has led to the deflection of blame from vaccine refusal to medical error in recent measles deaths.

How outlets are covering it

The Guardian and Ars Technica emphasize the ethical violations and the political connections to RFK Jr., noting that the researchers are currently under investigation for scientific misconduct in Denmark. They highlight the consensus among experts that the trial’s design was 'fanciful' and that the hepatitis B vaccine is safe and effective. In contrast, the primary source from Yahoo News frames the story as a failure of a 'bad idea' that was never viable, focusing on the inevitable collapse of the project due to lack of governmental approval. NDTV provides a more neutral summary of the police action and the halt, without explicitly detailing the political funding sources or the specific ethical arguments regarding the BCG vaccine interaction.

Why it matters

The halting of this trial highlights the tension between international public health guidelines and politically influenced research funding. The seizure of vaccines by local authorities threatens the immediate availability of a critical immunization for a country with high hepatitis B incidence. Furthermore, the uncertainty surrounding the $3.2 million in appropriated funds raises concerns about the diversion of resources away from universal vaccination programs, potentially leaving thousands of newborns unprotected against a preventable and potentially fatal disease.

What to watch

The CDC and private funders are expected to respond to inquiries regarding the reallocation of the $3.2 million in funding. Health experts are urging Guinea-Bissau to use the seized vaccines to roll out universal birth doses as soon as possible, rather than waiting for the planned 2028 schedule. Danish authorities may continue their investigation into the scientific misconduct of the Bandim Health Project researchers, while the WHO remains committed to ensuring timely, evidence-based protection for newborns in the region.
