      Objectives Elderly are an understudied, high-risk group vulnerable to severe COVID-19. We comprehensively analyzed the durability of humoral and cellular immune responses after BNT162b2 vaccination and SARS-CoV-2 infection ...

    • Durable T-cellular and humoral responses in SARS-CoV-2 hospitalized and community patients 

      Mohn, Kristin Greve-Isdahl; Bredholt, Geir; Zhou, Fan; Madsen, Anders Aasgaard; Onyango, Therese Bredholt; Fjelltveit, Elisabeth Berg; Jalloh, Sarah Larteley Lartey; Brokstad, Karl Albert; Cantoni, Diego; Mayora-Neto, Martin; Temperton, Nigel; Langeland, Nina; Cox, Rebecca Jane (Journal article; Peer reviewed, 2022)
      Background Neutralizing antibodies are important for protection against the pandemic SARS-CoV-2 virus, and long-term memory responses determine the risk of re-infection or boosting after vaccination. T-cellular responses ...

    • Lower antibiotic prescription rates in hospitalized COVID-19 patients than influenza patients, a prospective study 

      Fjelltveit, Elisabeth Berg; Cox, Rebecca Jane; Kittang, Bård Reiakvam; Blomberg, Bjørn; Buanes, Eirik A.; Langeland, Nina; Mohn, Kristin Greve-Isdahl (Journal article; Peer reviewed, 2022)
      Background COVID-19 patients are extensively treated with antibiotics despite few bacterial complications. We aimed to study antibiotic use in hospitalized COVID-19 patients compared to influenza patients in two consecutive ...

    • Point-of-care influenza testing impacts clinical decision, patient flow and length of stay in hospitalized adults 

      Fjelltveit, Elisabeth Berg; Brokstad, Rebecca Jane Cox; Østensjø, Jørgen; Blomberg, Bjørn; Ebbesen, Marit Helen; Langeland, Nina; Mohn, Kristin Greve Isdahl (Journal article; Peer reviewed, 2022)
      Background Influenza is difficult to distinguish clinically from other acute respiratory infections. Rapid laboratory diagnosis can help initiate early effective antiviral treatment and isolation. Implementing a novel ...

    • Post COVID-19 condition after delta infection and omicron reinfection in children and adolescents
