Atomization inhalation COVID-19 vaccine use the piezo atomizer

The world's first Atomization inhalation COVID-19 vaccineof CanSino Biologics inc uses the same vaccine as intramuscular injection, and its formulation has not changed, only a different way of administration is used. The advantage of CanSino Bio’s Atomization inhalation COVID-19 vaccine is that it has no adjuvant and is completely in the form of a liquid, so it can be inhaled by atomization. It passes through a micro-mesh, and after high-speed vibration, atomizes the vaccine liquid into particles with a diameter of less than 5 microns. If it is a large particle, it is impossible to be inhaled into the respiratory tract and lungs.
