Aerosolized vectors

Another mode of lung delivery for vector-containing fluid is by oral inhalation of aerosolized vectors. However, aerosolization of a fluid is typically achieved by means of a nebulizer, and most nebulizers have been designed to generate small particles. This is because they have been developed to deliver drugs to treat patients with asthma, and in asthma the target region of the lungs is often the peripheral airways.
