Background:

Genetic immunization shows promise as a vaccine delivery system.
Identifying target genes from large pathogen genomes for vaccines remains a significant challenge.

Purpose of the Study:

To address the challenge of identifying vaccine candidates from pathogens with large genomes.
To present 'expression library immunization' as a novel approach.

Main Methods:

Utilizing expression libraries within genetic immunization vectors.
Systematically analyzing pathogen genomes to isolate protective genes.

Main Results:

Expression library immunization provides a method to "strip down" pathogen genomes into individual genes.
This approach facilitates the identification of potential vaccine candidates.

Conclusions:

Expression library immunization offers a systematic and unbiased strategy for vaccine candidate discovery.
This method is particularly valuable for pathogens with complex genomes like bacteria and parasites.
