Pertussis vaccines: state-of-the-art and future trends

Area of Science:

• Immunology
• Microbiology
• Vaccinology

Background:

• Pertussis (whooping cough) is a significant global respiratory illness, primarily affecting infants.
• Current acellular pertussis (Pa) vaccines face challenges due to waning immunity and antigenic variation in Bordetella pertussis strains.
• Despite high vaccination rates, pertussis resurgence is observed in infants, adolescents, and adults, highlighting the need for improved vaccines.

Purpose of the Study:

• To address the resurgence of pertussis by exploring novel vaccination strategies.
• To identify new antigens from Bordetella pertussis for improved vaccine development.
• To investigate advanced proteomic and transcriptomic approaches for understanding host-pathogen interactions.

Main Methods:

• Utilizing advances in Bordetella pertussis proteomics, subproteomics, and immunoproteomics to identify novel antigens.
• Proposing future studies involving quantitative transcriptomic and proteomic profiling of host-B. pertussis interactions.
• Considering reverse vaccinology approaches for vaccine design.

Main Results:

• Recent proteomic studies have successfully identified novel antigens of Bordetella pertussis.
• These identified antigens offer potential for enhancing current acellular pertussis vaccines.
• Advanced profiling techniques are crucial for understanding pathogen behavior in vivo.

Conclusions:

• Improving acellular pertussis vaccines by incorporating new virulence factors is a rational strategy.
• Novel antigens identified through proteomics are key to developing next-generation pertussis vaccines.
• Future research in host-pathogen interactions and reverse vaccinology will be vital for long-term immunity.
