A personalized mRNA vaccine wiped out one patient’s glioblastoma, an aggressive brain tumor, with no chemo or radiation. Developed at Brigham and Women’s Hospital, the single-dose shot trained the immune system to attack the tumor’s unique mutations. Two years later, the patient remains cancer-free. Early trial, big promise. More testing is now underway. #CancerVaccine #Glioblastoma #mRNATherapy #MedicalBreakthrough #ImmunotherapyRevolution
