 (a) Phylogenetic tree comparing HA1 gene of H1N1 Indian isolates and vaccine components for the study period using the neighbor‐joining method. Scale bar indicates number of nucleotide substitutions per site. Solid dot indicates Northern Hemisphere vaccine components (Accession Nos. CY090286CY090430). (b) Phylogenetic tree comparing HA1 gene of H3N2 Indian isolates and vaccine components for the study period using the neighbor‐joining method. Scale bar indicates number of nucleotide substitutions per site. Solid dot indicates Northern Hemisphere vaccine components (Accession Nos. CY090431CY090572). (c) Phylogenetic tree comparing HA1 gene of influenza type B Indian isolates and vaccine components for the study period using the neighbor‐joining method. Scale bar indicates number of nucleotide substitutions per site. Solid dot indicates Northern Hemisphere vaccine components (Accession Nos. CY090573CY090737).
