Construction of a Generator for Dry Aerosols,
Abstract
Vaccination by dried antigen aerosols necessitates use of generators for solid particles of controlled size. This should be between 1 and 5 micrometers. In this case, the antigens could reach the lower respiratory passages and instigate local immunity. Production of liquid aerosols at controlled size is well known. On the contrary, it is very difficult to obtain a homogeneous powder and disperse it in aerosol form for inhalation. Phenomena of coalescence and hydration develop and the kinetics of settling are not very reproducible. The apparatus which we have used for the problem in the Microbiology Division seems to respond to the specific criteria that has been established.
