Abstract

mRNA vaccines have demonstrated potent and durable immune responses against various viral, bacterial, and cancer targets.

Lipid nanoparticles (LNPs) are crucial for stabilizing mRNA and enhancing its delivery into cells.
Advancements in mRNA chemistry, including nucleoside modification, have improved translation efficiency and immune response control.
The integration of biomaterial design with mRNA engineering is shaping the future of programmable immunotherapies.
Preclinical and clinical studies indicate that LNP-mRNA platforms could expand into both infectious and oncologic diseases.

Simplified

Messenger RNA (mRNA) vaccines have revolutionized immunotherapy by coupling modular mRNA engineering with advances in lipid nanoparticles (LNPs). LNPs, generally composed of ionizable lipid, phospholipid, cholesterol, and PEGylated lipid, have emerged as the leading vehicles for stabilizing mRNA and enhancing its cellular delivery. Concurrent innovations in mRNA chemistry and structure, such as nucleoside modification and untranslated region optimization, have improved translation efficiency, fidelity, and control of innate immune sensing. These synergistic advances underpinned the success of COVID-19 vaccines and have since propelled the rapid expansion of LNP-mRNA platforms across infectious and oncologic diseases. Preclinical and clinical studies now demonstrate potent and durable immune responses elicited by LNP-mRNA vaccines against diverse viral, bacterial, and cancer targets. Together, these findings illustrate how rational integration of biomaterial design with mRNA engineering defines the next generation of programmable immunotherapies. Continued refinement of both particle composition and mRNA architecture is poised to broaden the reach of mRNA nanomedicines across preventive and therapeutic domains.
