Abstract The highly mutated SARS-CoV-2 BA.2.87.1 lineage was recently detected in South Africa, but its transmissibility is unknown. Here, we report that BA.2.87.1 efficiently enters human cells but is more sensitive to antibody-mediated neutralization than the currently dominating JN.1 variant. Acquisition of adaptive mutations might thus be needed for high transmissibility.
