Recent advancements in understanding how cancer cells evade immune recognition have led to significant progress in cancer immunotherapy. Therapeutic cancer vaccines hold great promise due to their safety, specificity, and ability to establish lasting immune memory, serving as an effective immunotherapy either alone or in combination with other treatments in clinical research. Cancer vaccines aim to restore the host's innate and adaptive anti-cancer immune responses by stimulating antigen-presenting processes and reversing the immunosuppressive environment that facilitates tumor immune evasion and metastasis. Although in clinical studies cancer vaccines have been observed to not effectively induce tumor regression, they can enhance local immune responses in combination with other immunotherapeutic agents, such as immune checkpoint inhibitors (ICIs), thus delaying cancer recurrence and prolonging overall survival in advanced tumor settings.

Cancer vaccines represent a transformative shift in oncology, aiming to prevent malignancies or treat established cancers by training the immune system to recognize tumor-specific or tumor-associated antigens. This review explores the diverse platforms and mechanisms supporting cancer vaccines, ranging from prophylactic vaccines such as HPV and hepatitis B vaccines that have significantly reduced virus-related cancers to therapeutic vaccines like Sipuleucel-T and T-VEC that extend survival in prostate cancer and melanoma. Vaccine types are classified, and delivery platforms including mRNA, peptide, dendritic cell and viral vector-based approaches are examined alongside pivotal clinical trial outcomes.

Outer membrane vesicles (OMVs) are nanosized vesicles naturally secreted by Gram-negative bacteria and represent a promising platform for vaccine development. OMVs possess inherent immunostimulatory properties due to the presence of pathogen-associated molecular patterns (PAMPs), providing self-adjuvanting capabilities and the ability to elicit both innate and adaptive immune responses. This review outlines the advantages of OMVs over traditional vaccine strategies, including their safety, modularity, and the potential for genetic engineering to enable targeted antigen delivery.

Rationale: Cervical cancer is the fourth most common cancer affecting women worldwide, caused by persistent infection with oncogenic human papillomavirus (HPV) types. While HPV infections usually resolve spontaneously, persistent infections with high-risk HPV types can progress to premalignant glandular or - mostly - squamous intraepithelial lesions, usually classified in cervical intraepithelial neoplasia (CIN). Women with CIN 2 and CIN 3 (i.

Although traditional immunogenic cell death (ICD) inducers generate vaccines (ISV) to potentiate antiprogrammed cell death ligand 1 (anti-PDL1) antibodies therapy, their efficacy remains limited. This limitation may be attributed to the physical barrier created by extracellular matrix (ECM) and immunosuppressive metabolic barrier mediated by adenosine. Here, we report an oncolytic polymer (OP), a well-designed ε-polylysine derivative with ICD-inducing capacity, which can simultaneously facilitate the release of endogenous ECM-degrading enzyme, Cathepsin B.

Introduction: Immune-deficient/disordered people (IDP) elicit a less robust immune response to COVID-19 vaccination than the general US population. Despite millions of IDP at presumed elevated risk, few population-level studies of IDP have been conducted in the Omicron era to evaluate breakthrough infection-related outcomes.
Methods: We followed a prospective cohort of 219 IDP and 63 healthy volunteers (HV) in the USA from April 2021 (Alpha variant peak) to July 2023 (Omicron XBB variant peak).
