Dr. Steven Hatfill, a senior medical advisor at the U.S. Department of Health and Human Services (HHS), has recently given a highly critical interview regarding mRNA COVID-19 vaccines. Hatfill, who is a virologist and biodefense expert, has taken on a prominent role in the Administration for Strategic Preparedness and Response under HHS Secretary Robert F. Kennedy Jr. since early May 2025. He also previously served as an advisor during the first Trump administration and was a vocal proponent of hydroxychloroquine as a COVID-19 treatment, despite widespread scientific consensus that the drug was not effective for this purpose.
In his recent statements, Hatfill claims to have witnessed what he describes as cover-ups related to the mRNA vaccines and characterizes the vaccines as a dangerous experiment. He alleges that one of the key issues is the presence of an SV40 enhancer in the vaccine, which he claims can significantly increase gene expression in the body, likening it to accelerating a car without brakes. According to Hatfill, the vaccines also contain plasmid DNA, which he asserts can be integrated into human chromosomes by a cellular mechanism known as LINE-1. He warns that this integration could happen near genes related to cancer, potentially increasing cancer risk, and that the SV40 enhancer could worsen this effect by amplifying the expression of such genes. Hatfill further claims that studies have found spike protein from the vaccine, rather than from the virus, in tumors months after vaccination, and he asserts that there is a stronger association between cancer and vaccinated individuals than with those who were only infected by the virus.
Hatfill also disputes the claim that the vaccine remains localized at the injection site, referencing data from the Japanese Health Ministry that allegedly shows vaccine components spreading to multiple organs in animal studies. He suggests that this information was suppressed for financial gain.
He raises concerns about the lipid nanoparticles used to deliver the mRNA, stating that they can disrupt cells, cause allergic reactions, and damage organs. He also claims that the spike protein produced by the mRNA vaccines is toxic and can cause the body to attack itself, describing the vaccination process as making the body produce its own poison.
Hatfill describes the mRNA vaccine rollout as highly experimental, emphasizing that such technology had never before been tested on humans at this scale. He criticizes the clinical trials for allegedly excluding older adults, pregnant women, and children, and for selectively including healthy participants. He claims that data from these trials was mishandled or concealed, and he references Pfizer’s attempt to delay the release of trial data for decades.
He further alleges that there are signs of population-level consequences, such as declining testosterone in young men and potential fertility issues in women, citing animal studies and ongoing research into ovarian health in vaccinated women. Hatfill accuses professional organizations of ignoring miscarriage data and claims that the timing of vaccination during pregnancy can influence outcomes, but that these nuances were disregarded.
Hatfill blames a small group of federal officials and medical journal editors for what he sees as a betrayal of public trust, motivated by financial interests and conflicts of interest. He accuses these individuals of suppressing alternative treatments and pushing the vaccine despite safety concerns.
Hatfill expresses deep disillusionment with the medical establishment, stating that he once believed in the integrity of the profession but now feels betrayed. He calls for widespread awareness and accountability, asserting that the risks of mRNA vaccines-ranging from cancer and infertility to organ damage-are growing clearer and that the truth will eventually come to light.
It is important to note, however, that Hatfill has a history of promoting controversial and scientifically unsupported positions, such as his advocacy for hydroxychloroquine during the COVID-19 pandemic, which was not supported by robust clinical evidence and was rejected by the FDA and mainstream scientific community. His credentials and claims have also been questioned in the past, and he has been involved in high-profile controversies, including being wrongly suspected in the 2001 anthrax attacks. Mainstream medical authorities, regulatory agencies, and peer-reviewed studies have consistently found mRNA vaccines to be safe and effective for the vast majority of people, and claims of widespread harm or conspiracy have not been substantiated by credible scientific evidence.
