The scientists analyzed 13 vials from different lots of six brands of COVID-19 vaccines at the National University of Cordoba laboratory. They used a highly sensitive analytic technique – inductively coupled plasma mass spectrometry – which makes it possible to measure elements at trace levels in biological fluids.

The paper included a long list of COVID-19 vaccine components declared by the manufacturers, which the scientists obtained through public information requests.
They identified 55 chemical elements not listed on package inserts where found in the Pfizer, Moderna, AstraZeneca, CanSino, Sinopharm and Sputnik V COVID-19 vaccines. Their study was published in the International Journal of Vaccine Theory, Practice and Research.
"The detection of multiple undeclared toxic elements, including heavy metals and lanthanides, in COVID-19 vaccines raises a dual and multiplied concern for human health," said James Lyons-Weiler, Ph.D., a member of the journal's editorial board who was not involved in the research.
"Individually, these chemicals are known to cause neurological, cardiovascular and immunological damage. Together, their synergistic toxicity could exacerbate these risks far beyond what regulators and manufacturers have disclosed or studied."
The chemical elements include 11 heavy metals – such as chromium, arsenic, nickel, aluminum, cobalt and copper – which scientists consider systemic toxicants known to be carcinogenic and to induce organ damage, even at low exposure levels.
The samples also contained 11 of the 15 lanthanides, or rare earth elements, that are heavier, silvery metals often used in manufacturing. These chemical elements, which include lanthanum, cerium and gadolinium, are lesser known to the general public than heavy metals but have also been shown to be highly toxic.
The research builds on a series of studies conducted since 2021 using different analytic techniques to analyze COVID-19 vaccine vials from major manufacturers.
"This situation is even more urgent and concerning when we consider the rapid advancements observed in cutting-edge biotechnological developments, the complexity of which requires a more thorough legislative and regulatory framework to ensure the safety of individuals who choose to use these therapies," said Marcela Sangorrin, Ph.D., co-author of the study.
Previous studies also identified significant numbers of chemical elements not listed on vaccine labels. These research efforts include a 2022 study by a German working group, including the late pathologist Arne Burkhardt, submitted to the German government; a 2021 study by scientists in England; a 2022 study by Canadian Dr. Daniel Nagase; and a 2023 Romanian study by Dr. Geanina Hagima.
Meanwhile, Lyons-Weiler called for regulatory action to protect public health.
"Regulatory agencies must take immediate action to halt the use of these vaccines, thoroughly investigate how these toxins were missed, and ensure that the full spectrum of ingredients is transparently declared and the public duly and fully warned," he said.
Vaccines often include excipients – additives used as preservatives, adjuvants, stabilizers or for other purposes. According to the Centers for Disease Control and Prevention (CDC), substances used in the manufacture of a vaccine but not listed in the contents of the final product should be listed somewhere in the package insert.
Listing excipients is important because they may include allergens and other "hidden dangers" for vaccine recipients.
The OpenVAERS website offers a comprehensive list of vaccine of excipients by type and by vaccine. However, the website notes that independent tests of vaccine vials have found "contaminants that go well beyond those publicly disclosed by the manufacturers," as identified in the Argentine study.
In one lot of the AstraZeneca vaccine, the scientists identified 15 chemical elements, of which 14 were undeclared. In the other lot, they detected 21 elements of which 20 were undeclared. In the CanSino vial, they identified 22 elements, of which 20 were undeclared.
The three Pfizer vials contained 19, 16 and 23 undeclared elements, respectively. The Moderna vials contained as many as 29 undeclared elements. The Sinopharm vials contained between 17 to 23 undeclared elements and the Sputnik V contained between 19 to 25 undetected elements.
All of the heavy metals detected are linked to toxic effects on human health. Although the metals occurred in different frequencies, many were present across multiple samples.
"There are undeclared chemical elements in common, such as boron, calcium, titanium, aluminum, arsenic, nickel, chromium, copper, gallium, strontium, niobium, molybdenum, barium and hafnium in all of the brands," the scientists wrote.
