Variant profile of IAV-HA samples 2, 18 and 24. While no variant was found in sample #2, samples #18 and #24 have variants. Note that codons 213, 453 and 523 here are according to H1 numbering from first methionine. They would be codons 196, 436 and 506 respectively in Fig. 2 where H1 was numbered not from first methionine but without signal peptide
