Rabies vaccines: where do we stand, where are we heading?

Area of Science:

• Public Health
• Veterinary Medicine
• Virology

Background:

• Rabies is a lethal zoonotic viral disease with global distribution in wild animals.
• Existing vaccines are effective but require multiple doses and boosters, posing cost and accessibility challenges, particularly in low-income regions like sub-Saharan Africa and Southeast Asia.
• These factors impede widespread rabies control and eradication efforts.

Purpose of the Study:

• To provide an overview of recent advances in human rabies control strategies.
• To highlight challenges and future perspectives in global rabies prevention and management.
• To discuss the development of improved rabies vaccines and post-exposure prophylaxis.

Main Methods:

• Review of scientific literature and research advancements in rabies control over the past decade.
• Analysis of vaccine efficacy, cost-effectiveness, and delivery strategies.
• Examination of progress in developing novel anti-rabies antibodies and prophylactic measures.

Main Results:

• Significant progress has been made in understanding rabies virus transmission and pathogenesis.
• Development of more efficacious and potentially cheaper vaccine candidates is ongoing.
• Increased focus on integrated strategies for both animal and human rabies prevention.

Conclusions:

• Overcoming cost and logistical barriers of current rabies vaccines is crucial for global control.
• Continued research into novel vaccines and antibody therapies is essential for post-exposure prophylaxis.
• Future efforts must prioritize accessible and affordable rabies prevention, especially in endemic, low-resource settings.
