Prominent genomic recombination has been observed between the Delta and Alpha variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) isolated from clinical specimens in Japan. Interestingly, the recombination variant detected in this study carries a spike protein identical to the one in the domestic Delta variant, thereby suggesting that further risks would not be concerned with infectivity and immune escape. The recombinant has been classified as XC lineage in the PANGOLIN
