Keyword analysis identified seven major thematic clusters centered on outer membrane vesicles, bacterial antigens, antimicrobial resistance, computational approaches, and immunization strategies. Temporal analyses showed increasing attention to bioinformatics, reverse vaccinology, peptide\/epitope-based design, and virulence-associated targets.
