With the exception of the so-called cervical cancer vaccine, no shots have been approved specifically to prevent malignant tumors. But cervical cancer, which is caused by the sexually transmitted human papillomavirus (HPV), isn't the only tumor linked to a virus; another is cytomegalovirus (CMV), a usually harmless form of herpes that's the target of a possible therapeutic cancer vaccine for brain tumor patients.
