evidence: 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] [...] 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] [...] - ^ "False claims persist about COVID-19 vaccine-linked "turbo cancers"".
