[Immunocompromised individuals were identified early in the pandemic as being at increased risk of severe COVID-19 and demonstrated variable immune responses to SARS-CoV-2 vaccination. The findings support continued, tailored vaccination strategies for elderly and immunocompromised individuals. Integrating immune monitoring with infection history and adjunctive therapies may help refine booster policies, optimise protection, and strengthen future vaccination programmes for high-risk populations.]
