Nasal IgA wanes 9 months after hospitalisation with COVID-19 and is not induced by subsequent vaccination

2022-09-09

Abstract excerpt

<h4>Summary</h4> <h4>Background</h4> Most studies of immunity to SARS-CoV-2 focus on circulating antibody, giving limited insights into mucosal defences that prevent viral replication and onward transmission. We studied nasal and plasma antibody responses one year after hospitalisation for COVID-19, including a period when SARS-CoV-2 vaccination was introduced. <h4>Methods</h4> Plasma and nasosorption samples were...
