Saying that injecting 10 nanograms of random residual DNA is safe is like saying that smoking only one cigarette while pumping gas is OK, but not more than one.
Study finds DNA contamination in Pfizer Covid-19 vaccines
Experts warn that genetic fragments in inoculations might overstimulate the immune system, potentially leading to cancer
Pfizer’s mRNA Covid-19 vaccines contain residual DNA levels exceeding regulatory safety limits, according to a peer-reviewed study published this week in the Journal of High School Science.
The research was conducted by student scientists at the US Food and Drug Administration’s (FDA) White Oak Campus lab in Maryland.
Residual DNA refers to small pieces of genetic material that may remain in vaccines or medicines after manufacturing. These fragments come from the cells or processes used to make the products.
World Health Organization (WHO) guidelines state that a single vaccine dose should not contain more than 10 nanograms of residual DNA. The study, however, found levels in Pfizer’s vaccines exceeding this limit by six to 470 times.
Researchers analyzed vaccines obtained from BEI Resources, a supplier linked to the National Institute of Allergy and Infectious Diseases. They used NanoDrop and Qubit methods to measure DNA levels. Both methods showed contamination above acceptable thresholds. Residual DNA was found in six vials from two different vaccine lots.
While the study stated that health risks posed by the DNA fragments are “currently unknown,” researchers warned that, in theory, they could integrate into human DNA and increase the risk of gene mutations. They also raised concerns that the fragments may contain oncogenes, which could lead to cancer. The authors recommended further testing to assess the potential risks.
The FDA has not yet commented on the findings. While reports of DNA contamination in Covid-19 vaccines have been circulating for years, US regulatory authorities have repeatedly brushed them off, stating that they pose no health risks.

An explosive new study conducted within the U.S. Food and Drug Administration’s (FDA) own laboratory has revealed excessively high levels of DNA contamination in Pfizer’s mRNA COVID-19 vaccine.
Tests conducted at the FDA’s White Oak Campus in Maryland found that residual DNA levels exceeded regulatory safety limits by 6 to 470 times.
The study was undertaken by student researchers under the supervision of FDA scientists. The vaccine vials were sourced from BEI Resources, a trusted supplier affiliated with the National Institute of Allergy and Infectious Diseases (NIAID), previously headed by Anthony Fauci.
Recently published in the Journal of High School Science, the peer-reviewed study challenges years of dismissals by regulatory authorities, who had previously labelled concerns about excessive DNA contamination as baseless.
The FDA is expected to comment on the findings this week. However, the agency has yet to issue a public alert, recall the affected batches, or explain how vials exceeding safety standards were allowed to reach the market.
The Methods
The student researchers employed two primary analytical methods:
Both methods confirmed the presence of DNA contamination far above permissible thresholds. These findings align with earlier reports from independent laboratories in the United States, Canada, Australia, Germany and France.
Expert Reaction
Kevin McKernan, a former director of the Human Genome Project, described the findings as a “bombshell,” criticising the FDA for its lack of transparency.
“These findings are significant not just for what they reveal but for what they suggest has been concealed from public scrutiny. Why has the FDA kept these data under wraps?” McKernan questioned.
两种方法均证实 DNA 污染的存在远高于允许的阈值。 这些发现与美国、加拿大、澳大利亚、德国和法国独立实验室的早期报告一致。
专家反应
人类基因组计划前主任凯文·麦克南 (Kevin McKernan) 将这一发现描述为“重磅炸弹”，批评 FDA 缺乏透明度。
“这些发现的意义重大，不仅因为它们所揭示的内容，而且因为它们暗示的内容被隐瞒了公众的监督。 为什么 FDA 对这些数据保密？” 麦克南问道。
