Although vaccines are among therapies with the greatest impact on health, there is still a need to improve vaccine efficacy among groups with decaying immune function. By advancing the knowledge on reprogramming host immune responses by nanoparticulate systems, the ImmuneNanoVac project will lead to the identification of optimal nanomaterials to improve vaccine efficacy in vulnerable groups.
The protection afforded by vaccination (namely against influenza) is important but still sub-optimal. The exploitation of the results achieved with the development of nanomaterials for cancer immunotherapy, as well as the expertise in germinal center biology will boost vaccine responses through the use of nanoparticles to deliver adjuvants and immunizing antigens.
The ImmuneNanoVac project has the potential to increase vaccine efficacy among individuals that are more susceptible to severe consequences of infection, such as influenza or COVID-19.
Key Outcomes
- Optimal nanomaterials to improve vaccine efficacy in vulnerable groups;
- Research publications;
- Preliminary results to support further grant applications and intellectual property.
