Chitosan Nanoparticles Could Make Vaccines More Stable, Mucosal, and Needle-Free
A recent npj Vaccines review highlights chitosan‑based nanoparticles as a promising platform to stabilize fragile antigens, enable needle‑free administration, and boost mucosal immunity. By tweaking molecular weight, deacetylation and cross‑linking, researchers can tailor solubility, charge and degradation rates for optimal delivery. Preclinical data show spray‑dried chitosan powders retain potency for up to three months at 60 °C, suggesting reduced cold‑chain reliance. However, no chitosan nanovaccine has secured regulatory approval, with safety, stability and GMP‑grade material consistency still under scrutiny.
