The update highlights two key developments: the continued spread of\u00a0A (H3N2) subclade K\u00a0and the growing circulation of\u00a0new B\/Victoria lineage strains. In rapid response, Sino Biological, Inc., a global leader in recombinant technology, has launched a comprehensive panel of antigens for the 2026-2027 Northern Hemisphere influenza vaccine strains to accelerate influenza vaccine development.<\/p>\n<p>Decoding the 2026-2027 Northern Hemisphere influenza vaccine strains<\/p>\n<p>Since its indentification in August 2025, H3N2 subclade K (J.2.4.1) has become the dominant influenza A strain worldwide. Defined by the\u00a0T135K\u00a0and\u00a0S144N\u00a0mutations, this strain exhibits enhanced immune escape, prompting WHO\u2019s selection of\u00a0A\/Darwin\/1454\/2025 (egg-based, cell-based)\u00a0as the new H3N2 reference viruses. The H1N1 component has been updated to A\/Missouri\/11\/2025 (egg-based, cell-based).<\/p>\n<p>Alongside H3N2, influenza B activity is rising sharply. In regions such as Hong Kong and the U.S., the proportion of B\/Victoria lineage viruses recently increased from 6 % to over 20 %. These trends led WHO to recommendations\u00a0B\/Tokyo\/EIS13-175\/2025\u00a0(egg-based) and\u00a0B\/Pennsylvania\/14\/2025\u00a0(cell-based) strains for the upcoming season.<\/p>\n<p>Sino Biological\u2019s comprehensive reagents for 2026-2027 influenza vaccine research<\/p>\n<p>To support global influenza vaccine research and development, Sino Biological has launched an extensive portfolio of recombinant antigens for the 2026-2027 Northern Hemisphere influenza vaccine strains, spanning key viral antigens including Hemagglutinin (HA), Neuraminidase (NA), and Nucleoprotein (NP).
