The corona virus disease COVID-19 has changed the world since early 2020 in many ways. To combat the pandemic, researchers and companies around the world develop vaccines and medicines. Chitosan has potential in the area of vaccine development and functionalization of protective equipment such as respirators. We prepared reviews of recent publications about chitosan in the fight against corona.
The antiviral properties of chitosans, in contrast to chitosan derivatives, have been little considered. For this reason, the study presented here investigated the antiviral activity of three chitosans against the SARS-CoV-2 surrogate, bacteriophage phi6.
The global corona pandemic requires effective vaccines to achieve herd immunity. In the study presented here, an inhalable chitosan-based nanovaccine containing the viral spike protein (S) was developed to specifically induce immunity at the mucosal sites of the respiratory tract.
