Coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) leads to significant morbidity and mortality.

Recent studies have suggested that some patients have evidence of persistent defects in their immune system. These problems in the immune system can leave patients vulnerable to recurrent infections and autoimmunity and therefore a better understanding of the effect of COVID-19 infection on the immune system is required. We can test the immune system by assessment of the immune response following immunization with routine and safe vaccines.

In this study we will test immunize patients who have previously experienced COVID-19 infection to assess whether they have functional evidence of an immune defect.

Identification of immunodeficiency is important as this will help understand the long-term effects of COVID-19 on the immune system, alter future clinical management of these individuals and will have impact on public health measures.
