Cancer Vaccines in Pediatric Oncology
Cancer Vaccines in Pediatric Oncology
Cancer vaccines represent an innovative immunotherapeutic approach that harnesses the body's immune system to prevent, treat, or delay the progression of cancer in pediatric patients. These vaccines can be preventive (prophylactic) or therapeutic (treatment).
Key Principles
- Immune system activation against cancer-specific antigens
- Development of immunological memory
- Tumor microenvironment modification
- Integration with conventional therapies
Types of Cancer Vaccines
Preventive Vaccines
- HPV Vaccines
- Gardasil 9 (9-valent HPV vaccine)
- Prevention of HPV-related cancers
- Recommended age: 9-14 years
- Dosing schedule considerations
- Hepatitis B Vaccine
- Prevention of hepatocellular carcinoma
- Universal infant vaccination
- Long-term protection strategies
Therapeutic Vaccines
- Dendritic Cell Vaccines
- Personalized approach using patient's cells
- Ex vivo antigen loading
- Enhanced T-cell responses
- Peptide Vaccines
- Tumor-specific antigen targeting
- Multiple epitope presentation
- Adjuvant requirements
- Tumor Cell Vaccines
- Autologous or allogeneic cells
- Whole cell advantages
- Genetic modification potential
