Progress in African Swine Fever Vector Vaccine Development.

Area of Science:

• Veterinary Medicine
• Virology
• Immunology

Background:

• African swine fever (ASF) is a highly contagious and lethal disease impacting the global hog industry.
• Despite ongoing research, an effective commercial vaccine against the African swine fever virus (ASFV) remains undeveloped.
• Vector vaccines present a promising avenue for ASFV vaccine development due to their unique advantages.

Purpose of the Study:

• To review the characteristics of viral, bacterial, and yeast vector vaccines for ASF.
• To elucidate immunological mechanisms of antigens and identify potent antigen types.
• To discuss the use of cytokines and advancements in vector vaccine technology for ASFV.

Main Methods:

• Review of existing literature on vector vaccine platforms (viral, bacterial, yeast).
• Analysis of immunological responses to various antigens.
• Evaluation of cytokine applications for enhanced vaccine efficacy.
• Synthesis of current trends and challenges in ASFV vector vaccine research.

Main Results:

• Identified key characteristics and immunological mechanisms of different vector vaccine types.
• Highlighted potential antigens and the role of exogenously expressed cytokines.
• Summarized common vector types and recent technological advancements.

Conclusions:

• Vector vaccines show significant promise for controlling African swine fever.
• Further research into antigen selection, cytokine enhancement, and vector optimization is essential.
• Development of effective ASFV vaccines is critical for mitigating global economic losses.
