The present invention relates to a method of preparing a live attenuated vaccine by irradiation and a live attenuated vaccine composition prepared by the same, and more particularly, a method of preparing a live attenuated vaccine by irradiation including irradiating a pathogenic microorganism with a dose of 0.5 to 2 kGy of radiation per single radiation six to fifteen times; and a live attenuated vaccine composition including a pathogenic microorganism attenuated to not be revertant to a wild type by generation of at least one mutation of nucleotide insertion and nucleotide deletion by irradiation.

The present disclosure provides a composition for preventing an immune disorder, recovering from an immune disorder, preventing an immune disorder from occurring and preventing or treating a disease, disorder or condition. The present disclosure provides a composition for preventing an immune disorder, recovering from an immune disorder, preventing an immune disorder from occurring and preventing or treating a disease, disorder or condition in a subject, said composition comprising an antigen component, which is specific to the subject (or immunological memory of which remains in the subject), against a component which is different from a causative factor of the disease, disorder or condition.

Disclosed herein are immunogenic compositions (e.g., vaccines) for use in the treatment of mycobacteria infections and biomarkers for monitoring of therapeutic responsiveness to the immunogenic compositions in a subject (e.g., a human). In a first aspect, the disclosure features a pharmaceutical composition containing between 1×10{circumflex over ( )}2 CPU and 1×10{circumflex over ( )}10 CPU of a Mycobacterium tuberculosis strain (Mtb) with one or more mutations that ablate or reduce expression of LprG and Rv1410 (ΔLprG Mtb) in a volume of between 0.05 mL and 3 mL.
