Abstract

Serology, the study of blood serum and its components, plays a crucial role in pandemic preparedness and response by providing essential insights into the prevalence, spread, and impact of infectious diseases. During pandemics, serological testing helps to identify past infections, determine the extent of immune responses, and assess the effectiveness of vaccines. By analyzing antibody levels, serology can distinguish between current and past infections, offering valuable data for epidemiological surveillance and public health strategies. Additionally, serological surveys contribute to understanding population immunity and guiding policy decisions related to quarantine measures, vaccination programs, and resource allocation. As pandemics evolve, serology remains a key tool in adapting response strategies and mitigating the impact of infectious outbreaks on global health.
