Immunotherapies, such as immune checkpoint inhibitors, have revolutionized cancer treatment by enhancing the immune system’s ability to recognize and attack cancer cells. Combining these therapies with breast cancer vaccines can enhance the immune response and improve treatment outcomes. The synergistic effects of combining different modalities are being explored to overcome the immunosuppressive nature of the tumour microenvironment and achieve better therapeutic responses.

B. Identification of Promising Vaccine Targets

Analysis of potential antigen targets

Experts in JAMA Oncology have extensively analyzed potential antigen targets for breast cancer vaccines. These targets include tumour-specific antigens (TSAs) and tumour-associated antigens (TAAs). TSAs are unique to cancer cells and not expressed in normal cells, making them attractive targets for vaccine development. TAAs, on the other hand, are expressed by both cancer cells and normal cells but at higher levels in cancer cells, allowing for selective targeting. Understanding these antigens’ expression patterns and immunogenicity is crucial for developing effective breast cancer vaccines.

Insights into the selection of optimal target antigens

Selecting the most appropriate target antigens for breast cancer vaccines. Experts suggest that ideal antigens should be highly expressed in breast cancer cells, essential for tumour growth or survival, and capable of eliciting a robust immune response. Comprehensive genomic profiling and proteomic analyses can aid in identifying potential antigens that meet these criteria. Additionally, experts emphasize the importance of considering antigen heterogeneity within tumours, as different subclones may express distinct antigens. Understanding the antigenic landscape of breast tumours can guide the selection of optimal target antigens for vaccine development.
