Turbo cancer is an anti-vaccination conspiracy theory [1] alleging that people vaccinated against COVID-19, especially with mRNA vaccines, are suffering from a high incidence of fast-developing cancers. Although the idea has been spread by a number of vaccine opponents, including doctors, [2] turbo cancer is not supported by cancer research, and there is no evidence that COVID-19 vaccination causes or worsens cancer. [3] [4] [5]
Opponents of COVID-19 vaccines such as Florida surgeon general Joseph Ladapo have claimed that trace amounts of contaminant DNA present alongside the vaccine's mRNA could integrate in the patient's genome, activating oncogenes responsible for cancer. In response, Céline Gounder pointed out that trace DNA exists in virtually every product originating from cell cultures, and that DNA vaccines are not known to cause cancer despite containing much higher amounts of DNA. [6] According to the US National Cancer Institute, "[t]here is no evidence that COVID-19 vaccines cause cancer, lead to recurrence, or lead to disease progression. Furthermore, COVID-19 vaccines do not change your DNA". [5]
A paper by antivaccine activists Stephanie Seneff, Peter McCullough and others claimed suppression of type 1 interferon could result in immune suppression that could promote cancer proliferation. [7] The study suggested hypothetical disease mechanisms linking mRNA vaccines to various pathologies through immune suppression. It used only anecdotal reports from VAERS as evidence, and was described by Jeffrey Morris as "shifting the burden of proof" by asking public health institutions to either prove the impossibility of these mechanisms or accept them. [8]
Similarly, a Frontiers in Oncology paper discussing a laboratory mouse dying of lymphoma after being injected with the Pfizer–BioNTech COVID-19 vaccine was claimed to prove the existence of turbo cancer. However, the study in question did not claim any causality between the two events. Notably, the type of mouse used in the study had a higher predisposition to sarcomas and lymphomas, with that specific individual having shown signs of preexisting cancer such as weight loss before the vaccine injection. The setup of the study was also criticized, as it differed from human vaccinations in the method of injection (intravenous rather than intramuscular) and dose in proportion to body weight (480 to 600 times higher). [9] [10] [11] The authors later added that their findings were "largely misinterpreted". [12]
Vernon Edward Coleman is an English conspiracy theorist and writer, who writes on topics related to human health, politics and animal welfare. He was formerly a general practitioner (GP) and newspaper columnist. Coleman's medical claims have been widely discredited and described as pseudoscientific conspiracy theories.
Food and Chemical Toxicology is a peer-reviewed scientific journal covering aspects of food safety, chemical safety, and other aspects of consumer product safety. It is published by Elsevier and was established in 1963. The editor-in-chief is Bryan Delaney.
Moderna, Inc. is a pharmaceutical and biotechnology company based in Cambridge, Massachusetts, that focuses on RNA therapeutics, primarily mRNA vaccines. These vaccines use a copy of a molecule called messenger RNA (mRNA) to carry instructions for proteins to produce an immune response. The company's name is derived from the terms "modified", "RNA", and "modern".
John Barthelow Classen is an American immunologist and opponent of vaccination. He received his M.D. from the University of Maryland, Baltimore in 1988, his M.B.A. from Columbia University in 1992 and obtained his medical license in October 1997. He is best known for publishing research concluding that vaccines, in particular the Hib vaccine, cause insulin-dependent diabetes mellitus, a hypothesis he proposed based on experiments he conducted on mice in 1996. His views are disputed and considered unverified.
Stephanie Seneff is an American computer scientist and anti-vaccinationist. She is a senior research scientist at the Computer Science and Artificial Intelligence Laboratory (CSAIL) of the Massachusetts Institute of Technology (MIT). Working primarily in the Spoken Language Systems group, her research at CSAIL relates to human–computer interaction, and algorithms for language understanding and speech recognition. In 2011, she began publishing controversial papers in low-impact, open access journals on biology and medical topics; the articles have received "heated objections from experts in almost every field she's delved into," according to the food columnist Ari LeVaux.
An mRNAvaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. The vaccine delivers molecules of antigen-encoding mRNA into immune cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen or by a cancer cell. These protein molecules stimulate an adaptive immune response that teaches the body to identify and destroy the corresponding pathogen or cancer cells. The mRNA is delivered by a co-formulation of the RNA encapsulated in lipid nanoparticles that protect the RNA strands and help their absorption into the cells.
A COVID‑19 vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID‑19).
Uğur Şahin is a German oncologist and immunologist. He is the founder and CEO of BioNTech, which developed one of the major vaccines against COVID-19. His main fields of research are cancer research and immunology.
The Pfizer–BioNTech COVID-19 vaccine, sold under the brand name Comirnaty, is an mRNA-based COVID-19 vaccine developed by the German biotechnology company BioNTech. For its development, BioNTech collaborated with the American company Pfizer to carry out clinical trials, logistics, and manufacturing. It is authorized for use in humans to provide protection against COVID-19, caused by infection with the SARS-CoV-2 virus. The vaccine is given by intramuscular injection. It is composed of nucleoside-modified mRNA (modRNA) that encodes a mutated form of the full-length spike protein of SARS-CoV-2, which is encapsulated in lipid nanoparticles. Initial guidance recommended a two-dose regimen, given 21 days apart; this interval was subsequently extended to up to 42 days in the United States, and up to four months in Canada.
Misinformation related to immunization and the use of vaccines circulates in mass media and social media in spite of the fact that there is no serious hesitancy or debate within mainstream medical and scientific circles about the benefits of vaccination. Unsubstantiated safety concerns related to vaccines are often presented on the internet as being scientific information. A large proportion of internet sources on the topic are mostly inaccurate which can lead people searching for information to form misconceptions relating to vaccines.
Michael Yeadon is a British anti-vaccine activist and retired pharmacologist who attracted media attention in 2020 and 2021 for making false or unfounded claims about the COVID-19 pandemic and the safety of COVID-19 vaccines. The Times has described him as "a hero of Covid conspiracy theorists" and "a key figure in the antivax movement". Until 2011, he served as the chief scientist and vice-president of the allergy and respiratory research division of the drug company Pfizer, and is the co-founder and former CEO of the biotechnology company Ziarco.
Peter Andrew McCullough is an American cardiologist. He was vice chief of internal medicine at Baylor University Medical Center and a professor at Texas A&M University. From the beginnings of the COVID-19 pandemic, McCullough has promoted misinformation about COVID-19, its treatments, and mRNA vaccines.
Robert Wallace Malone is an American physician and biochemist. His early work focused on mRNA technology, pharmaceuticals, and drug repurposing research. During the COVID-19 pandemic, Malone promoted misinformation about the safety and efficacy of COVID-19 vaccines.
COVID-19 vaccine clinical research uses clinical research to establish the characteristics of COVID-19 vaccines. These characteristics include efficacy, effectiveness, and safety. As of November 2022, 40 vaccines are authorized by at least one national regulatory authority for public use:
In many countries a variety of unfounded conspiracy theories and other misinformation about COVID-19 vaccines have spread based on misunderstood or misrepresented science, religion, and law. These have included exaggerated claims about side effects, misrepresentations about how the immune system works and when and how COVID-19 vaccines are made, a story about COVID-19 being spread by 5G, and other false or distorted information. This misinformation, some created by anti-vaccination activists, has proliferated and may have made many people averse to vaccination. This has led to governments and private organizations around the world introducing measures to incentivize or coerce vaccination, such as lotteries, mandates, and free entry to events, which has in turn led to further misinformation about the legality and effect of these measures themselves.
John Lorimer Campbell is an English YouTuber and retired nurse educator known for his videos about the COVID-19 pandemic. Initially, the videos received praise, but they later veered into misinformation. He has been criticised for suggesting COVID-19 deaths have been over-counted, repeating false claims about the use of ivermectin as a COVID-19 treatment, and providing misleading commentary about the safety of COVID-19 vaccines. As of March 2024, his YouTube channel had 3 million subscribers and over 750 million views.
