Claim:
A method for administering a vaccine, the method comprising the steps of: providing a vaccine; combining the vaccine with at least one nebuliser device, wherein the at least one nebuliser device produces a plurality of vaccine particles from the vaccine; using a particle size analyzer to measure a particle droplet size distribution of the plurality of vaccine particles produced from the at least one nebuliser device; administering the plurality of vaccine particles from the at least one nebuliser device to a patient, wherein the plurality of vaccine particles have the following particle droplet size distribution: (i) D v10 : 2.0+/−0.2 μm (ii) D v50 : 5.0+/−0.5 μm (iii) D v90 : 10.0+/−1.0 μm (iv) a mean mass aerodynamic diameter (MMAD) having a range with a lower limit above 5.0 μm and an upper limit at 8.0 μm.
