“… 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 Subsequent Omicron subvariants emerged in waves, with a subvariant replacing the previous one every few months. We and others have evaluated the virological features, replication, and pathogenicity of these dominant Omicron subvariants, including BA.1, 6 , 7 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 42 , 43 , 44 , 45 , 46 BA.2, 23 , 24 , 25 , 26 , 35 , 47 , 48 , 49 and BA.5. 27 , 28 , 36 , 40 , 41 , 50 , 51 , 52 , 53 , 54 , 55 , 56 More recently, the emerged post-BA.2/5 subvariants were unable to successfully outcompete other subvariants to become the dominant Omicron lineage worldwide, leading to the cocirculation of multiple Omicron subvariants.…”
