Turbo cancer

Last updated

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 several health professionals, [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]

Claims

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]

Examples of claims

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]

mRNA vaccine Type of vaccine

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 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.

<span class="mw-page-title-main">Pfizer–BioNTech COVID-19 vaccine</span> Type of vaccine for humans

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.

A nucleoside-modified messenger RNA (modRNA) is a synthetic messenger RNA (mRNA) in which some nucleosides are replaced by other naturally modified nucleosides or by synthetic nucleoside analogues. modRNA is used to induce the production of a desired protein in certain cells. An important application is the development of mRNA vaccines, of which the first authorized were COVID-19 vaccines.

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.

In many countries, the dissemination of varied claims and perspectives regarding COVID-19 vaccines has sparked widespread public discussion. These include concerns about potential side effects, differing interpretations of how the immune system responds to vaccination, and debates over the development and distribution of COVID-19 vaccines. Additionally, stories such as COVID-19 being linked to 5G technology and other debated information have also emerged. This spread of information, including content from anti-vaccination advocates, may have influenced people's attitudes towards vaccination. In response, governments and private organizations around the world have introduced measures to encourage or mandate vaccination, such as lotteries, mandates, and free entry to events. These measures have further fueled debates about their legality and effectiveness.
