Abstract

Viral pathogenesis, the study of how viruses cause disease in hosts, has become increasingly crucial in light of recent global health crises, particularly the COVID-19 pandemic. Understanding the mechanisms by which viruses interact with host cells and evade immune responses is essential for developing effective vaccines and therapeutic strategies. This article emphasizes the implications of viral pathogenesis for vaccine development, highlighting the challenges posed by rapidly mutating viruses, as seen in HIV and coronaviruses. Additionally, it discusses the importance of a multidisciplinary approach to enhance global health security and outbreak preparedness. Ethical considerations regarding research funding and prioritization in the context of competing health concerns are also addressed. Ultimately, a robust understanding of viral pathogenesis is vital for anticipating and responding to viral threats, ensuring the health and safety of populations worldwide
