Cancer vaccines face misinformation that hinders their progress in patient care[1][6][7]. The HPV vaccine protects against cervical cancer, which is caused by this sexually transmitted virus, but disinformation channels claim that it causes sterilization or kills women[2][8]. There is no evidence that covid vaccination causes cancer, blood clots or organ damage from spike proteins because the vaccine spike protein is modified and localized[1][3][4]. The term "turbo cancer" is not medically recognized and claims of its association with vaccination are misleading, without proof of causality[3][5]. Experimental cancer vaccines, including protein and mRNA types, show a positive effect on immunity and life extension in tests[6][7]. Metformin is associated with a lower risk of esophageal cancer, according to a study in JAMA Network Open[original content].
