Senate hearing set to review research on COVID-19 vaccines, cancer concerns

A U.S. Senate investigative hearing is set to spotlight growing controversy over claims that COVID-19 vaccines may be associated with increased cancer risks, as a group of scientists and medical experts prepare to present research they say warrants urgent public scrutiny.

The hearing, titled “Plausible Mechanisms of COVID-19 Injections Causing Cancer and Attacks on Scientific Publications,” will be conducted by the Permanent Subcommittee on Investigations, chaired by Senator Ron Johnson of Wisconsin.

The session is expected to feature testimony from several prominent researchers and physicians, including Professor Angus Dalgleish, emeritus professor of oncology at City St George’s, University of London; Dr. Wafik El-Deiry, director of the Legorreta Cancer Center at Brown University; Dr. Sabine Hazan, chief executive officer of genetic sequencing laboratory ProgenaBiome; Dutch pediatric oncologist Dr. Saskia Mostert; and British cardiologist and public health advocate Dr. Aseem Malhotra.

According to information released ahead of the hearing, witnesses will discuss scientific studies and proposed biological mechanisms that they believe may explain a potential connection between COVID-19 vaccinations and certain forms of cancer.

The hearing will also examine claims that researchers who raised concerns about vaccine safety or promoted alternative COVID-19 treatments faced resistance from scientific institutions, public health agencies, and technology platforms.

Central to the discussion is a recent systematic review co-authored by El-Deiry and Dr. Charlotte Kuperwasser, a professor at Tufts University School of Medicine.

The review analyzed 69 studies and reports and identified what the authors described as possible safety signals linking COVID-19 vaccines and SARS-CoV-2 infection to cancers such as leukemia, lymphoma, breast cancer, and lung cancer.

The researchers proposed several biological pathways that could potentially contribute to cancer development, including the effects of spike proteins and reports of DNA contamination identified in some vaccine analyses.

However, the authors also emphasized that mRNA-based technologies continue to show promise in cancer treatment and should remain subjects of ongoing clinical research.

El-Deiry recently claimed that LinkedIn removed a post in which he shared information from the review, labeling the content as misinformation. Writing on social media platform X, he argued that scientific debate surrounding vaccine safety should not be restricted.

The Senate hearing is also expected to explore allegations of censorship and suppression of scientific literature related to COVID-19 treatment strategies.

Dr. Hazan, a gastroenterologist and microbiome researcher, has publicly stated that several of her peer-reviewed studies concerning COVID-19 treatments and microbiome research were retracted without publicly disclosed explanations.

According to the review, the study reported statistically significant associations between COVID-19 vaccination and six cancer types: breast, colorectal, gastric, lung, prostate, and thyroid cancers. Researchers also reported a 27 percent increase in overall cancer incidence among vaccinated individuals included in the analysis.

Speaking during a “Make Britain Healthy Again” event, Malhotra told attendees that Dalgleish considered it highly likely that COVID-19 vaccination had been a significant factor in the cancer diagnoses of King Charles III and Catherine, Princess of Wales.

The remarks generated significant controversy in the United Kingdom and prompted some medical professionals to call on the General Medical Council (GMC) to investigate Malhotra’s statements.

Dalgleish later confirmed to medical journal The BMJ that he had expressed similar views to Malhotra prior to the conference.

While the scientists scheduled to testify argue that emerging evidence merits closer examination and further research, many public health authorities and mainstream medical organizations continue to maintain that available evidence does not establish a causal relationship between COVID-19 vaccination and cancer and that the vaccines remain a critical tool in preventing severe disease and death from COVID-19.
