Experts warn that genetic fragments in inoculations might overstimulate the immune system, potentially leading to cancer
Pfizerβs 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 Administrationβs (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 Pfizerβs 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.

Pfizer has been under investigation several times. One notable case occurred in 2009 when Pfizer paid $2.3 billion to settle a Department of Justice investigation into illegal marketing practices for several of its drugs.
This marked the biggest healthcare fraud settlement in history at the time.
