The hearing, titled “Plausible Mechanisms of COVID-19 Injections Causing Cancer and Attacks on Scientific Publications,” was convened by Senator Ron Johnson, who chairs the Permanent Subcommittee on Investigations. Multiple medical professionals described patterns they have witnessed in their practices.

Dr. Angus Dalgleish, a professor emeritus of oncology at the University of London, testified that beginning in late 2021 he observed unexpected cancer relapses in patients who had been in stable remission for years, consistently following COVID-19 booster administration. He described seeing a sudden wave of aggressive recurrences in early 2022, with the common factor being a recent booster dose.
