The inhalable new crown vaccine is currently in the clinical trial stage and is not open for application to the public for the time being.
At present, the first batch of inhalable new crown vaccine in China has entered the clinical trial stage and is being applied for emergency use. The inhalable vaccine is more convenient, comfortable and safer than the injectable vaccine, and can reduce the physical and mental stress of vaccination for some people, such as minors.
Inhalable NeoCrown vaccine is based on the principle of using a nebulizer to transform the vaccine into tiny droplets that can be inhaled through the respiratory tract to stimulate mucosal immunity, which can also be effective.
In order to ensure the safety and effectiveness of the vaccine for various groups of people, the inhalation vaccine is still in the stage of clinical trials in China, and will not be used on a large scale for the time being.
