Two British doctors will testify before a powerful US Senate subcommittee today, bringing their claims of serious harms linked to Covid-19 vaccines — including potential connections to cancer — to the heart of American political oversight.
The hearing, convened by the United States Senate Permanent Subcommittee on Investigations and chaired by Republican Senator Ron Johnson of Wisconsin, is titled “Plausible Mechanisms of Covid-19 Injections Causing Cancer and Attacks on Scientific Publications.” Senator Johnson, a prominent critic of the pandemic response who has repeatedly called for greater scrutiny of vaccine safety data, has praised the two medics as “highly credentialed and experienced doctors” with the “courage to expose the truth.” It is understood that President Trump will be informed of the proceedings.
The subcommittee has a long history of probing major scandals — from the collapse of Enron and the conduct of Wall Street banks after the 2008 financial crash to opioid manufacturers and government failures during national emergencies. In a letter inviting Dr Aseem Malhotra to appear, Senator Johnson said the panel wanted evidence on the cardiologist’s “work studying the mechanism through which Covid-19 vaccines may cause cancer” and his “experiences with the peer review process in scientific publications.”
The hearing’s central allegations
The session will examine claims that senior US regulators adopted a safety surveillance algorithm that critics maintain was known to hide signals of serious adverse events, including sudden death. According to prepared opening remarks, senators will be told that regulators “decided to use a safety surveillance algorithm they knew would — and did in fact — hide safety signals on extremely serious adverse events, including sudden death.” The hearing is also expected to hear that pharmaceutical companies spent billions of dollars on television advertising “to capture the narrative” and used lobbying and political influence to shape public policy — an allegation that echoes concerns raised in previous investigations by Senator Johnson, who has held hearings on what he calls the “corruption of science” in federal health agencies. The US Food and Drug Administration and the Centers for Disease Control and Prevention operate passive and active surveillance systems including the Vaccine Adverse Event Reporting System (VAERS) and the Sentinel BEST system, but critics argue that the FDA has directed scientists to withdraw peer-reviewed studies on vaccine safety, amounting to suppression of pro-safety findings.
Dr Aseem Malhotra: from advocate to critic
Dr Malhotra, a leading cardiologist and former NHS adviser, was once among the most trusted voices urging vaccine uptake. He will tell senators that he was “requested to appear on Good Morning Britain to help tackle vaccine hesitancy amongst high-risk ethnic minority groups.” But his position changed dramatically after the sudden death of his father, Dr Kailash Chand, honorary vice-president of the British Medical Association, who died of an unexpected cardiac arrest at the age of 73. “My fit and healthy 73-year-old father, honorary vice president of the British Medical Association, who also happened to be my best friend and last surviving member of my immediate family, died after suffering an unexpected cardiac arrest,” Dr Malhotra will say. He argues that evidence published afterwards led him to conclude that Covid vaccination contributed to his father’s death.

Dr Malhotra says he later published peer-reviewed papers calling for a moratorium on mRNA Covid vaccines. “The most damning evidence was a re-analysis of Pfizer and Moderna’s original trials,” he will state. “It determined a frequency of serious harm from the product that was two to four times more likely than being hospitalised with severe COVID.” He will warn senators that “millions across the world may be in clear and present danger of suffering premature cardiovascular disease and cancer” and that without open scientific debate, it will be impossible to identify who is most at risk or how those risks can be mitigated. Dr Malhotra has also faced criticism for making claims linking Covid vaccines to cancer in members of the Royal Family — remarks widely dismissed by medical bodies and scientists, and which the UK’s General Medical Council is reportedly examining.
Professor Angus Dalgleish: oncologist’s clinical observations
Professor Angus Dalgleish, professor emeritus of oncology at the University of London and a pioneer of cancer immunotherapy and HIV research, will present his observations from clinical practice. “Beginning in late 2021, I observed a series of unexpected cancer relapses and unusually aggressive disease presentations among patients whose conditions had remained stable for years,” he will tell the subcommittee. “A consistent pattern quickly became apparent: these relapses followed repeated Covid booster administration.” He says his concerns then widened: “I began observing something far more alarming: unusually aggressive cancers, advanced-stage disease in younger individuals, and clinical presentations that differed sharply from what we would normally expect in routine oncology practice.”
Professor Dalgleish will argue that the “consistency of these clinical observations, combined with emerging mechanistic evidence, should have prompted far greater scientific scrutiny and open investigation than they received.” He will also say scientists became increasingly reluctant to discuss potential concerns, adding: “Science does not advance through silence, suppression, or reputational protection. It advances through rigorous inquiry, transparent debate, independent replication, and the courage to follow evidence wherever it leads.” He is expected to call for an independent investigation into “the potential relationship between repeated mRNA vaccination, immune dysregulation, and aggressive cancer progression, particularly in vulnerable populations.” Professor Dalgleish has previously stated that he believes Covid injections are associated with a global increase in cancers, suggesting they may suppress the immune system, and has reportedly told Dr Malhotra that it was “highly likely” the vaccines were a significant factor in the cancers of members of the Royal Family.
Disputed claims and scientific consensus
Both doctors have faced professional and political pushback in Britain. Former Health Secretary and Prime Minister Sir Keir Starmer criticised Dr Malhotra for his claims about the health risks of the jabs. The testimony now being heard in Washington is disputed by regulators, vaccine manufacturers and many scientists, who maintain that Covid vaccine side effects are rare and that the vaccines prevented millions of hospitalisations and deaths worldwide. Numerous studies and systematic reviews have affirmed the safety and efficacy of the vaccines. Senator Johnson’s previous hearings on vaccine injuries and what he describes as the “corruption of science” in federal health agencies have been characterised by critics as platforms for anti-vaccine rhetoric and misinformation. The Senate subcommittee will now weigh the evidence presented by the two British doctors against the established scientific consensus that continues to underpin global vaccination programmes.
