Judicial police in Guinea-Bissau raided the offices of vaccine researchers, seizing doses of the hepatitis B vaccine. These researchers have been recognized and praised by Robert F. Kennedy Jr., the US Department of Health and Human Services secretary.

The raid is part of an ongoing dispute concerning research on African newborns, which has attracted significant funding. The project has received $1.6 million from the US Centers for Disease Control and Prevention (CDC), with matching contributions totaling $3.2 million from the Pershing Square Foundation and the Bluebell Foundation.

Officials announced the police search occurred on Monday, stating it was part of "investigative procedures aimed at clarifying the circumstances related to the said batch of vaccines." The announcement, translated from Portuguese, also noted that the seizure did not imply any issues with the "quality, safety, or effectiveness of the vaccines."

The Bandim Health Project, the research entity involved, recently shared approval letters for the trial. These included one from Guinea-Bissau’s national ethics committee, dated July 14, and another from a Danish research ethics committee that had to adapt its protocols to review the trial.

However, the health minister of Guinea-Bissau’s transitional government, Quinhin Nantote, has disputed reports that the trial would proceed. "This is not even remotely true," Nantote stated in an interview. The study was reportedly redesigned over the summer, but still proposed withholding hepatitis B vaccines from 7,000 newborns in their first six weeks of life.

This proposal has drawn criticism, particularly in a country where approximately one in five adults are living with the hepatitis B virus. Hepatitis B can lead to cancer and liver failure, with newborns being especially susceptible. Vaccination within 24 hours of birth is considered a safe and highly effective preventive measure.

Critics have argued that any study withholding this vaccine from participants is unethical and unnecessarily exposes newborns to significant health risks. The controversy highlights the complex ethical considerations in international health research, especially when involving vulnerable populations and potentially life-saving interventions.

Questions remain regarding the exact nature of the police investigation, the future of the Bandim Health Project's research in Guinea-Bissau, and the potential implications for international vaccine research funding and oversight.
