Selection of adjuvants for vaccines targeting specific pathogens

Area of Science:

• Vaccinology
• Immunology
• Biotechnology

Background:

• Adjuvants are crucial in inactivated and subunit vaccine formulations.
• They are essential for eliciting robust innate and adaptive immune responses against pathogens.
• Proper adjuvant selection tailors immune responses to specific pathogen characteristics.

Purpose of the Study:

• To review recent advancements in understanding adjuvant mechanisms.
• To discuss adjuvants used in licensed human vaccines or in clinical/pre-clinical development.
• To explore how omics technologies and systems vaccinology aid in adjuvant discovery.

Main Methods:

• Review of current literature on adjuvant mechanisms.
• Analysis of licensed and developmental adjuvants.
• Discussion of omics-based technologies and systems vaccinology in adjuvant research.

Main Results:

• Adjuvant technology has significantly evolved in the last two decades.
• Understanding innate immune system activation by adjuvants is key.
• Systems vaccinology approaches facilitate novel adjuvant development.

Conclusions:

• Adjuvants are critical for vaccine efficacy, guiding immune responses.
• Novel adjuvants are being developed for challenging pathogens and specific populations.
• Continued research into adjuvant mechanisms promises improved vaccine design.
