Abstract:
Despite proven effectiveness, vaccine uptake in high-risk groups remains low due to access barriers, misinformation, and limited trial data. In this Forum, we discuss how targeted communication, optimized vaccine formulations, inclusive trials, and real-world effectiveness studies can help close protection gaps in vulnerable populations.

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
