TUMOR THERAPEUTIC
VACCINES EXPLAINED
How cancer vaccines train the immune system to find and destroy tumor cells โ a next-generation approach to personalized cancer immunotherapy.
What Are Therapeutic Cancer Vaccines?
Unlike preventive vaccines (HPV, Hepatitis B), therapeutic cancer vaccines treat existing cancer. They present tumor-specific antigens to the immune system, training it to recognize and destroy cancer cells. This is a highly personalized approach to immunotherapy.
โTherapeutic cancer vaccines turn the patient's own tumor mutations into targets for immune attack.โ
Types of Therapeutic Cancer Vaccines
mRNA Vaccines
Encode tumor neoantigens in mRNA, prompting the body to produce antigens and mount an immune response. Moderna's mRNA-4157 is the most advanced candidate.
Neoantigen Vaccines
Custom-designed based on mutations unique to each patient's tumor. Requires whole-exome sequencing and bioinformatics to identify targets.
Dendritic Cell Vaccines
Patient's dendritic cells are loaded with tumor antigens ex vivo and re-infused to activate T-cells. Sipuleucel-T (Provenge) was the first FDA-approved example.
Peptide Vaccines
Synthetic peptides matching tumor antigens are injected with adjuvants to stimulate immune recognition. Broadly tested across cancer types.
Key Cancer Vaccine Programs
| Vaccine | Type | Cancer | Phase |
|---|---|---|---|
| mRNA-4157 + Keytruda | mRNA neoantigen | Melanoma (adjuvant) | Phase 3 |
| Sipuleucel-T (Provenge) | Dendritic cell | Prostate cancer | FDA approved |
| GEN-009 | Neoantigen peptide | Multiple solid tumors | Phase 1/2 |
| BNT111 | mRNA (shared antigens) | Advanced melanoma | Phase 2 |
| NeoVax | Neoantigen peptide | Melanoma, glioblastoma | Phase 1/2 |
How Vaccine Personalization Works
Personalized cancer vaccines require multi-step tumor profiling to identify targets.
Tumor Biopsy & Sequencing
Whole-exome or RNA sequencing identifies mutations unique to the patient's tumor.
Neoantigen Prediction
Bioinformatics algorithms predict which mutations will generate strong immune responses.
Vaccine Design & Manufacturing
Selected neoantigens are encoded into the vaccine platform (mRNA, peptide, or DC).
Vaccination & Immune Monitoring
Patient receives the vaccine; T-cell responses are monitored to confirm activation.
Frequently Asked Questions
About Cancer Vaccines
How CancerFax Helps
CancerFax is a specialist cancer access and patient-navigation platform. We help patients and families understand their options, organise medical records, coordinate hospital communication, and support cross-border treatment planning where appropriate.
We help collect and organise reports, scans, pathology, biomarker results, and treatment history for structured case review.
We communicate with hospitals or trial teams to assess whether a case may be suitable for further screening.
We support appointment coordination, document submission, translation, and direct communication with international departments.
For international patients, we help with practical coordination โ travel planning, hospital admission guidance, and local support.
If this option is not suitable, we help explore other relevant treatments, clinical trials, or advanced care pathways.
From inquiry through to follow-up, our coordinators provide a single point of contact for the family.
CancerFax does not guarantee treatment access, eligibility, or clinical outcome. Our role is to help patients access accurate information, structured review, and appropriate specialist pathways.
