Receptor-binding domain-based subunit vaccines against MERS-CoV

Area of Science:

• Virology and Immunology
• Vaccine Development

Background:

• Middle East respiratory syndrome (MERS) is a continuous public health threat caused by MERS coronavirus (MERS-CoV).
• Effective vaccines are needed to prevent MERS transmission in humans and camels.

Purpose of the Study:

• To review the structure of the MERS-CoV spike (S) protein and its receptor-binding domain (RBD).
• To discuss current MERS vaccine development status and strategies for RBD-based subunit vaccines.
• To summarize animal models for MERS-CoV and propose future vaccine directions.

Main Methods:

• Literature review of MERS-CoV structure, vaccine development, and animal models.
• Analysis of strategies for developing receptor-binding domain (RBD)-based subunit vaccines.

Main Results:

• Detailed description of MERS-CoV spike protein and RBD structure.
• Overview of current MERS vaccine development efforts and methodologies.
• Summary of available animal models for MERS-CoV research.

Conclusions:

• RBD-based subunit vaccines offer a promising and safe approach for MERS prevention.
• This review provides a roadmap for researchers developing MERS-CoV vaccines.
• Findings are applicable to developing vaccines against future pandemic-causing coronaviruses.
