Bovine Viral Diarrhea Virus and Vaccine Protection Strategies

Area of Science:

• Veterinary Virology
• Immunology
• Epidemiology

Background:

• Bovine viral diarrhea virus (BVDV) poses a major threat to global cattle health and economies.
• Persistent infection, immunosuppression, and reproductive issues are key BVDV-induced problems.
• Viral genetic diversity and immune evasion mechanisms complicate BVDV control.

Purpose of the Study:

• To review the challenges in BVDV control and prevention.
• To evaluate limitations of current BVDV vaccines.
• To explore novel vaccine platforms and integrated control strategies for BVDV.

Main Methods:

• Literature review of BVDV pathogenesis, epidemiology, and control strategies.
• Analysis of limitations associated with inactivated (IVs) and modified live (MLVs) BVDV vaccines.
• Assessment of emerging vaccine platforms (mRNA, subunit, multi-epitope) and AI-driven design.

Main Results:

• BVDV persistently infects cattle, creating reservoirs for transmission and causing economic losses.
• Conventional vaccines have limitations including subtype mismatch and safety concerns.
• Novel platforms like mRNA and multi-epitope vaccines show promise for improved BVDV immunity.

Conclusions:

• Effective BVDV control requires addressing limitations of current vaccines and exploring new technologies.
• AI-driven design and molecular surveillance can enhance vaccine development.
• Integrated strategies including PI animal clearance, vaccination, and biosecurity are vital for sustainable BVDV management.
