      Background: Results showing that sera from double vaccinated individuals have minimal neutralizing activity against Omicron have been interpreted as indicating the need for a third vaccine dose for protection. However, there is little information about early immune responses to Omicron infection in double vaccinated individuals.<p> <p>Methods: We measured inflammatory mediators, antibodies to the ...

    • High circulating levels of the homeostatic chemokines CCL19 and CCL21 predict mortality and disease severity in Covid-19

      Background. Immune dysregulation is a major factor in the development of severe coronavirus disease 2019 (COVID-19). The homeostatic chemokines CCL19 and CCL21 have been implicated as mediators of tissue inflammation, but data on their regulation in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is limited. We thus investigated the levels of these chemokines in COVID-19 ...

    • Omicron Variant Generates a Higher and More Sustained Viral Load in Nasopharynx and Saliva Than the Delta Variant of SARS-CoV-2 

      Granerud, Beathe Kiland; Ueland, Thor; Lind, Andreas; Søraas, Arne Vasli; Fevang, Børre; Steffensen, Anne Katrine; Al-Baldawi, Huda; Lund-Johansen, Fridtjof; Aukrust, Pål; Halvorsen, Bente Evy; Dahl, Tuva Børresdatter; Dudman, Susanne; Müller, Fredrik; Holter, Jan Cato (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-31)
      The Omicron variant of SARS-CoV-2 spreads more easily than earlier variants, possibly as a result of a higher viral load in the upper respiratory tract and oral cavity. Hence, we investigated whether the Omicron variant generates a higher viral load than that of the Delta variant in saliva and nasopharynx. Both specimens were collected from 52 Omicron and 17 Delta cases at two time points one week ...
