Generation and characterization of a cold-adapted attenuated live H3N2 subtype influenza virus vaccine candidate.

Chinese medical journal, 2010
H3N2 subtype influenza A viruses have been identified in humans worldwide, raising concerns about their pandemic potential and prompting the development of candidate vaccines to protect humans against this subtype of influenza A virus. The aim of this study was to establish a system for rescuing of a cold-adapted high-yielding H3N2 subtype human ...

WHO recommendations for influenza virus vaccine 2002/03

, 2002
The new subtype of the influenza A virus, A(H1N2), is a combination of components present in the strains of the two influenza A subtypes (H1N1 and H3N2) currently contained in the vaccine, and so people who have received the vaccine should have a good ...

Cross-sectional study on protective antibodies against influenza A virus subtypes and cross-protection against influenza A(H3N2) subclade K, Portugal, August 2025

Eurosurveillance
The 2025/26 season was marked by co-circulation of influenza A subtypes, with the first detection of A(H3N2) subclade K in September 2025. In August 2025 in Portugal, 14.8% (95% CI: 12.2–17.8) of 886 persons tested had cross-protective antibodies against this subclade.

Amino acid 138 in the HA of a H3N2 subtype influenza A virus increases affinity for the lower respiratory tract and alveolar macrophages in pigs

PLOS Pathogens
Influenza A virus (FLUAV) infects a wide range of hosts and human-to-swine spillover events are frequently reported. However, only a few of these human viruses have become established in pigs and the host barriers and molecular mechanisms driving adaptation to the swine host remain poorly understood.
