Researchers have created an inhalable COVID-19 vaccine that is shelf stable at room temperature for up to three months, targets the lungs specifically and effectively, and allows for self-administration via an inhaler. The researchers also found that the delivery mechanism for this vaccine – a lung-derived exosome called LSC-Exo – is more effective at evading the lung’s mucosal lining than the lipid-based nanoparticles currently in use, and can be used effectively with protein-based vaccines.
