Inhaled vaccines
In a method for creating an immune response, a vaccine is prepared in the form of a dry powder. The powder particles have an aerodynamic particle size range from 1-100 microns. A dose of powder is loaded into a dry powder inhaler. The dose is inhaled with an inspiratory flow rate of less than 60 liters per minute. A mucosal immune response is created via particles of the vaccine material depositing on the upper respiratory tract. A systemic immune response is created via particles of the vaccine material depositing into the deep lung. The vaccine material is size reduced by e.g., jet milling, into the desired range, yet vaccine potency is retained.
