(A) MEGA-7 software was used to construct a neighbor-joining tree using a Tamura 3-parameter model with gamma distribution (0.5) and a bootstrap replication of 1000 cycles. The reference sequences of SARS-CoV-2 VOCs are shown along with the sequences obtained from specimens collected during breakthrough infection (EPI_ISL_11208201) marked with green color and Reinfection (EPI_ISL_11211347) marked with brown color. (B) Single nucleotide variation in the ORF 1a, ORF1 b, S, ORF 3a, E, M, ORF 6, ORF7ab, ORF 8 and N genes and its frequency in the two sequences of Breakthrough (EPI_ISL_11208201) and Reinfection (EPI_ISL_11211347). The X-axis is the SNVs and Y-axis represents the frequency.
