Longitudinal serological response to SARS-CoV-2 among rohingya refugees in cox’s bazar, Bangladesh: implications for pandemic preparedness in humanitarian settings
This study demonstrates robust antibody responses following natural SARS-CoV-2 infection and a marked rise-but rapid decline-of vaccine-induced immunity among Rohingya refugees. The findings highlight the need for timely booster doses, strengthened vaccination coverage, and continued serological monitoring to maintain protective immunity in high-density humanitarian settings. These insights can support targeted public health interventions and pandemic preparedness strategies for displaced and vulnerable populations.
