Abstract: Disclosed are a nebulization cup and application in nebulized inhalation administration thereof, and especially application in nebulized inhalation administration of a preventive and/or therapeutic drug for a respiratory disease (such as SARS-CoV-2 vaccine). After adding an antistatic agent, the nebulization cup can effectively maintain the stability of drug mist within a certain period of time, with stable particle size, less drug residue in the cup, thus ensuring effective inhalable amount, and the administration operation is simple and convenient, thus the nebulization cup can significantly improve the inoculation efficiency and can be used for large-scale inoculation.

Abstract: Disclosed is a SARS-CoV-2 vaccine, wherein the S protein of SARS-CoV-2 serves as the antigen, and the vaccine comprises an adenoviral vector, and the vaccine induces an improved protective immune response through mucosal immunity, thus preventing SARS-CoV-2 infection. Specifically, when atomized by an appropriate apparatus, the vaccine generates particles of improved uniformity, which can reach the lungs after being inhaled via the nasal cavity or the oral cavity, thus producing a protective immune response with respect to the entire respiratory tract and the lungs, enhancing the effective utilization rate of the vaccine, and increasing the effect of the vaccine.
