• To discuss challenges and future directions in neoantigen prediction, vaccine formulation, and clinical implementation.
• To explore combination strategies for enhanced therapeutic efficacy.

Main Methods:

• Systematic review of recent literature on personalized breast cancer vaccines.
• Analysis of neoantigen identification, vaccine platforms, and nano-delivery systems.
• Examination of pharmacological aspects, immune activation, and resistance mechanisms.

Main Results:

• Personalized vaccines show promise for inducing specific anti-tumor immunity in breast cancer.
• Technological progress is driving the development of more efficient and accessible personalized vaccines.
• Combination strategies with immune checkpoint inhibitors, radiotherapy, and chemotherapy are being explored to overcome the tumor microenvironment.

Conclusions:

• Personalized cancer vaccines hold significant potential for improving breast cancer treatment outcomes.
• Addressing challenges in prediction, formulation, and delivery is crucial for widespread adoption.
• Further research and clinical translation are needed to fully realize the benefits of these immunotherapies.
