Abstract

---

Influenza is a viral respiratory infection that affects tens of thousands of people every year. Each year, the marketed influenza vaccines target the most commonly predicted strains. However, even with the moderate success of the 2019 flu vaccine at 47% protective, there still remains some shortcomings for the currently marketed flu vaccinations. Hence, to potentially overcome inssues with cross-protectivity, another approach involves utilizing a matrix protein, matrix-2 protein (M2e), which is a highly conserved protein in A strains of the influenza virus. To increase the immunogenicity of M2e, multiple repeats of the protein were combined to form a virus-like particle (VLP). The VLP was then encapsulated into a polymeric microparticulate (MP) formulation to improve uptake by antigen presenting cells (APCs) and induce long term antigen release in the body. Additionally, many individuals do not receive the flu vaccine currently because of invasive intramuscular injections. Therefore, the proposed VLP MP vaccine was delivered transdermally through various devices and vaccine.
