Smart Hydrogel Microneedle Patches for mRNA Nanoparticle Vaccination

Project description

Smart patches for mRNA vaccines

mRNA vaccines currently rely on painful injections and strict refrigeration, which often discourages patients and limits global distribution. Supported by the Marie Skłodowska-Curie Actions programme, the SHINE-Vax project aims to develop a painless, ‘smart’ microneedle patch that adapts to the wearer’s body temperature. Using special dual-layered hydrogels, the patch will release an initial vaccine pulse at normal body temperature and maintain a steady dose to reinforce immunity, but it will automatically pause delivery during a fever to enhance safety. By protecting mRNA within advanced nanoparticles, the project is expected to reduce reliance on expensive cold-chain logistics. Ultimately, SHINE-Vax seeks to make vaccinations more effective and accessible, ensuring life-saving medicine reaches even the most resource-limited communities.

Objective

The COVID-19 pandemic highlighted the transformative potential of mRNA vaccines, yet their delivery remains confined to intramuscular injections, which cause discomfort, reduce compliance, and rely on cold-chain logistics. Microneedle patches offer a minimally invasive alternative, but current systems mainly provide single-burst, fixed-dose release, limiting safety and efficacy. This project, SHINE-Vax, develops a temperature-responsive hydrogel microneedle system for controlled mRNA vaccine delivery. Dual hydrogel layers with distinct phase transitions enable an initial release pulse at normal body temperature (~37 °C), sustained low-dose diffusion to reinforce immunity, and reversible suppression under fever-like conditions (~39 °C). Encapsulated lipid/polymer nanoparticles preserve mRNA integrity and stability, reducing cold-chain dependence. By integrating materials engineering, nanotechnology, and vaccine science, SHINE-Vax will deliver a proof-of-concept prototype (TRL 2–3) demonstrating autonomous, adaptive release. This innovation aims to enhance vaccine efficacy and safety while broadening accessibility, particularly in resource-limited settings, positioning Europe at the forefront of next-generation, patient-friendly vaccination technologies.
