      Hansen, Lena; Brokstad, Karl Albert; Bansal, Amit; Zhou, Fan; Bredholt, Geir; Onyango, Therese Bredholt; Sandnes, Helene Heitmann; Elyanow, Rebecca; Madsen, Anders; Trieu, Mai Chi; Sævik, Marianne; Søyland, Hanne; Olofsson, Jan Stefan; Vahokoski, Juha; Ertesvåg, Nina Urke; Fjelltveit, Elisabeth Berg; Shafiani, Shahin; Tøndel, Camilla; Chapman, Heidi; Kaplan, Ian; Mohn, Kristin Greve-Isdahl; Langeland, Nina; Cox, Rebecca Jane (Journal article; Peer reviewed, 2023)
      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 ...

    • Functional and Binding H1N1pdm09-Specific Antibody Responses in Occasionally and Repeatedly Vaccinated Healthcare Workers: A Five-Year Study (2009-2014) 

      Amdam, Håkon; Madsen, Anders; Zhou, Fan; Bansal, Amit; Trieu, Mai Chi; Cox, Rebecca Jane (Journal article; Peer reviewed, 2021)
      Background: In 2009, a novel influenza A/H1N1pdm09 emerged and caused a pandemic. This strain continued to circulate and was therefore included in the seasonal vaccines up to the 2016/2017-season. This provided a unique ...

    • Persistently high antibody responses after AS03-adjuvanted H1N1pdm09 vaccine: Dissecting the HA specific antibody response 

      Madsen, Anders; Jul-Larsen, Åsne; Trieu, Mai Chi; Krammer, Florian; Cox, Rebecca Jane (Journal article; Peer reviewed, 2021)
      Current influenza vaccines have a suboptimal effectiveness. The introduction of a novel A/H1N1 influenza virus in 2009 (H1N1pdm09) provided a unique opportunity to study the humoral response to the AS03-adjuvanted H1N1pdm09 ...

    • Prospects and challenges in the development of universal influenza vaccines 

      Madsen, Anders; Brokstad, Rebecca Jane Cox (Journal article; Peer reviewed, 2020-07-06)
      Current influenza vaccines offer suboptimal protection and depend on annual reformulation and yearly administration. Vaccine technology has rapidly advanced during the last decade, facilitating development of next-generation ...

    • A rapid antibody screening haemagglutination test for predicting immunity to SARS-CoV-2 variants of concern
