Claim 0:
1. A method for producing an immunogenic composition comprising:
(a) neutering an intact pathogenic source, wherein neutering the pathogenic source involves:
destroying the genetic material of the pathogenic source by varying a dosage and/or a wavelength of UV-C radiation such that the pathogenic source is unable to reproduce or cause infection while leaving intact at least some or all of its membrane or structural proteins as antigens; and

(b) aliquoting the neutered pathogenic source into containers,
wherein the pathogenic source is neutered in a disinfectant unit comprising:
a housing that is opaque to UV-C radiation/light; and
a chamber enclosed within the housing, wherein the chamber comprises:
(i) a chamber wall that is transparent to UV-C light;
(ii) a chamber inlet;
(iii) a chamber outlet;
(iv) a centralized inner bore having an interior chamber surface facing the inner bore;
(v) one or more UV-C light source positioned adjacent the interior surface; and
(vi) a helical air flow diverter centralized within the inner bore proximal the one or more UV-C light sources, wherein the helical air flow diverter comprises one or more rungs, wherein the helical airflow diverter creates a centrifugal force and a helical path for the airflow pathway as the airflow pathway proceeds from the housing inlet to the housing outlet, and
wherein varying the dosage and wavelength of the UV-C radiation involves:
(A) controlling one or more of the following parameters:
(i) intensity of UV-C emitted by the one or more UV-C light sources;
(ii) number, type and position of the one or more UV-C light sources; and
(iii) number of disinfectant units and/or number of chambers per disinfectant unit; and/or

(B) controlling the exposure time of the pathogenic source to the UV-C by adjusting or varying one or more of the following parameters:
(i) height of the chambers per disinfectant unit to thereby increase the height of the helical air flow diverter,
(ii) number of helical rungs,
(iii) a surface on the chamber wall with reflecting and/or irregular or crenulated walls to increase light ray reflections;
(iv) speed of the air flow through the device,
(v) a diameter of the helical rungs to control the proximity of the UV-C light source to the pathogens,
(vi) air flow velocity through the disinfectant unit(s); and
(vii) length of an air stream pathway through the disinfectant unit.
