  • Antibody-dependent cellular cytotoxicity against SARS-CoV-2 Omicron sub-lineages is reduced in convalescent sera regardless of infecting variant 
    Richardson, Simone I.; Kgagudi, Prudence; Manamela, Nelia P.; Kaldine, Haajira; Venter, Elizabeth M.; Pillay, Thanusha; Lambson, Bronwen E.; Van der Mescht, Mieke Adri; Hermanus, Tandile; Balla, Sashkia R.; De Beer, Zelda; De Villiers, Talita R.; Bodenstein, Annie; Van den Berg, Gretha; Du Pisanie, Marizane; Burgers, Wendy A.; Ntusi, Ntobeko A.B.; Abdullah, Fareed; Ueckermann, Veronica; Rossouw, Theresa; Boswell, Michael T.; Moore, Penny L. (Cell Press, 2023-01)
    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.4 and BA.5 variants caused major waves of infections. Here, we assess the sensitivity of BA.4 to binding, neutralization, and antibodydependent cellular ...
  • SARS-CoV-2 Omicron triggers cross-reactive neutralization and Fc effector functions in previously vaccinated, but not unvaccinated, individuals 
    Richardson, Simone I.; Madzorera, Tatenda; Spencer, Holly; Manamela, Nelia P.; Van der Mescht, Mieke Adri; Lambson, Bronwen E.; Oosthuysen, Brent; Ayres, Frances; Makhado, Zanele; Moyo-Gwete, Thandeka; Mzindle, Nonkululeko; Motlou, Thopisang; Strydom, Amy; Mendes, Adriano; Tegally, Houriiyah; De Beer, Zelda; De Villiers, Talita Roma; Bodenstein, Annie; Van den Berg, Gretha; Venter, Marietjie; De Oliviera, Tulio; Ueckermann, Veronica; Rossouw, Theresa M.; Boswell, M.T.; Moore, Penny L. (Cell Press, 2022-03-24)
    The SARS-CoV-2 Omicron variant escapes neutralizing antibodies elicited by vaccines or infection. However, whether Omicron triggers cross-reactive humoral responses to other variants of concern (VOCs) remains unknown. We ...
  • T cell responses to SARS-CoV-2 spike cross-recognize Omicron
