Antibody responses after influenza and SARS-CoV-2 vaccination and infection: Lessons across the ages
Ertesvåg, Nina Urke (Doctoral thesis, 2023-10-23)Influensa A og SARS-CoV-2 er RNA-baserte luftvegsvirus som forårsakar pandemiar og muterer raskt for å oppretthalde ein kontinuerleg sirkulasjon. Eit komplekst samspel mellom immunresponsar hjå verten og viruset er forma ... -

We comprehensively analyzed the durability of humoral and cellular immune responses after BNT162b2 vaccination and SARS-CoV-2 infection ... -
Persistent Fever and Positive PCR 90 Days Post-SARS-CoV-2 Infection in a Rituximab-Treated Patient: A Case of Late Antiviral Treatment
Ertesvåg, Nina Urke; Sakkestad, Sunniva Todnem; Zhou, Fan; Hoff, Ingrid; Kristiansen, Trygve; Jonassen, Trygve Müller; Follesø, Elisabeth; Brokstad, Karl Albert; Dyrhovden, Ruben; Mohn, Kristin Greve-Isdahl (Journal article; Peer reviewed, 2022)Background: Persistent fever after SARS-CoV-2 infection in rituximab-treated patients has been reported. Due to reduced sensitivity in conventional sampling methods and unspecific symptoms in these patients, distinguishing ... -
