“…In contrast to WGS, amplicon deep sequencing focuses on a specific gene or genomic region, providing a greater sequencing depth and coverage while reducing costs and data burden. Sanger-based approaches have been previously employed ( Bezerra et al, 2021 , Goes et al, 2021 ). These are either focused on a small window in the S gene, and hence missing relevant SNPs flanking said region, or target SNPs prevalent to specific VOC/VOIs.…”
