FDA Study by Student Researchers Finds DNA Contamination in Pfizer's mRNA Vaccines Exceeds Limits by 6 to 470 Times
Jan 3, 2025, 06:17 AM
Recent studies and reports have raised concerns about the presence of DNA contamination in Pfizer's mRNA COVID-19 vaccines. A study conducted at the FDA's White Oak Campus in Maryland by student researchers found that residual DNA levels in the vaccines exceeded regulatory safety limits by 6 to 470 times. The vaccine vials were sourced from BEI Resources, affiliated with the National Institute of Allergy and Infectious Diseases. The findings, published in the Journal of High School Science, challenge previous dismissals by regulatory authorities regarding concerns about DNA contamination. The FDA has yet to issue a public alert or recall the affected batches. The study used NanoDrop and Qubit analyses to confirm the presence of DNA contamination, aligning with reports from independent laboratories in several countries. Kevin McKernan, a former director of the Human Genome Project, criticized the FDA for a lack of transparency, while Nikolai Petrovsky, a Professor of Immunology, described the findings as a 'smoking gun.' Experts have highlighted potential cancer-causing mechanisms related to the contamination.
