Rift Valley fever vaccines: current and future needs.

Area of Science:

• Veterinary Medicine
• Public Health
• Epidemiology

Background:

• Rift Valley fever (RVF) is a zoonotic, mosquito-borne illness impacting ruminants and humans.
• RVF outbreaks lead to substantial economic losses and public health crises in endemic areas.
• Vaccination is key to preventing RVF, but its implementation is inconsistent despite evidence of viral activity.

Purpose of the Study:

• To highlight the importance of vaccination strategies for Rift Valley fever control.
• To emphasize the need for robust networks in managing RVF.
• To underscore the necessity of preparedness for RVF alerts and outbreaks.

Main Methods:

• Review of existing literature on RVF epidemiology and control.
• Analysis of factors influencing vaccination strategy implementation.
• Assessment of the role of national and international networks in disease response.

Main Results:

• RVF causes severe reproductive losses in livestock and varied illness in humans.
• Inconsistent vaccination practices hinder effective RVF outbreak prevention.
• Strong multidisciplinary networks are vital for vaccine availability and deployment.

Conclusions:

• Strategic vaccination is essential for mitigating RVF's impact.
• Functional national and international networks are critical for successful RVF vaccination campaigns.
• Preparedness and coordinated response are key to managing RVF risks in high-risk zones.
