Nano-Vaccines: Opportunities and Challenges in Biomaterial-Based Vaccine Delivery

Nano-vaccines have significant cutting-edge advancement in immunization, which presents a transformative avenue for vaccine delivery using biomaterial-based platforms. These vaccines utilize nanoscale materials, such as lipids, polymers, and proteins, to engineer precise and efficient immune responses. The distinct physicochemical characteristics of nano-vaccine carriers allow for customized antigen, controlled release kinetics, and increased uptake by antigen-presenting cells. Biomaterial advancements are employed for biomedical applications and offer potential solutions for challenges in cancer vaccine development. This chapter explores the design and clinical progress of diverse cancer vaccine classes, with various components such as DNA (Deoxyribonucleic acid), mRNA (messenger RNA), peptides/proteins, and those based on cells. Additionally, it explores innovative biomaterial delivery platforms enhancing vaccine safety and efficacy. However, addressing the problems related to manufacturing, safety, regulation, and accessibility is imperative to fully harness the potential of nano-vaccines and usher in a new era of effective and personalized immunization strategies. This summary explores both the opportunities and challenges that are inherent in biomaterial-based nano-vaccine delivery.
