Abstract:

Human exposure to pathogens and the transmission of viruses have been increasing due to a more interconnected world, rising global mobility, growing urban population density, and the effects of climate change. As these trends continue, societies are experiencing more frequent and successive outbreaks of infectious diseases, which pose significant threats to global health, healthcare infrastructure, and both economic and social stability. The persistent vaccine equity gap leaves countries in sub-Saharan Africa especially vulnerable to the severe consequences of modern epidemics. Addressing this complex challenge requires recognizing the multifaceted barriers—ranging from healthcare and socioeconomic disparities to cultural, educational, technological, geographic, political, regulatory, and environmental obstacles—that limit equitable access to resources [1, 2, 3]. In the context of behavioral epidemiology, transparent and open risk communication by governments is critical to building public trust, encouraging participation, and reducing vaccine hesitancy. This paper explores the intricate web of constraints contributing to vaccine inequity and outlines a comprehensive, multi-pronged strategy to help close the global vaccine equity gap
