The hemagglutinin of the influenza A(H1N1)pdm09 is mutating towards stability
Advances and Applications in Bioinformatics and Chemistry, 2014 The last influenza A pandemic provided an excellent opportunity to study the adaptation of the influenza A(H1N1)pdm09 virus to the human host. Particularly, due to the availability of sequences taken from isolates since the beginning of the pandemic until date, we could monitor amino acid changes that occurred in the hemagglutinin (HA) as the virus ...

Influenza and Other Respiratory Viruses, Volume 20, Issue 9, September 2026.ABSTRACT Background Seasonal influenza, especially in persons with underlying medical conditions, is a substantial global burden. Influenza vaccination effectiveness (VE) varies annually, requiring continuous evaluation due to evolving viruses and vaccination coverages. Our aim was to investigate influenza VE in preventing hospitalization for confirmed

Effects of Sequential Influenza A(H1N1)pdm09 Vaccination on Antibody Waning [PDF]
The Journal of Infectious Diseases, 2019 Antibody waning following influenza vaccination has been repeatedly evaluated, but waning has rarely been studied in the context of longitudinal vaccination history.We developed a Bayesian hierarchical model to assess the effects of sequential influenza A(H1N1)pdm09 vaccination on hemagglutination inhibition antibody boosting and waning in a ...

Clinical &Translational Immunology, Volume 15, Issue 8, 2026.Abstract Objectives Recent outbreak of influenza A/H5N1 viral infections in birds and mammals worldwide prompted renewed concerns over an emerging H5N1‐related influenza pandemic in the generally immunologically‐naive global population. Cross‐reactive CD4+ T cells between A/H1N1 and A/H5N1 subtypes targeting internal and surface influenza proteins have
