Egg-derived HA sequence analysis. (A) Sequence alignment of vaccine strain Singapore INFIMH-16-0019 (SING16) and its egg-derived HA (SING16+egg). (B) Sequence alignment of vaccine strain A/HongKong/4801/2014 (HK14) and its egg-derived HA (HK14_egg). X at position 203 is mixed-sequence chromatograms that correlate to either T or I; X at position 225 is mixed-sequence chromatograms that correlate with either D or G. (C) Mapping the egg-derived mutations on the structure. Singapore INFIMH-16-0019 egg-derived mutations (red), A/HongKong/4801/2014 egg-derived mutation (salmon), and shared egg-derived mutations (purple) are indicated.
