Samenvatting

The emergence of SARS-CoV-2 variants raised questions regarding the durability of immune responses after homologous or heterologous booster vaccination after Ad26.COV2.S priming. We found that SARS-CoV-2-specific binding antibodies, neutralizing antibodies and T-cells are detectable 5 months after boosting, although waning of antibodies and limited cross-reactivity with Omicron BA.1 was observed.
