Africa's Struggle to Meet Global Pandemic Influenza Immunization Targets: Lessons for Public Health Policy and Preparedness—A Focus on Ghana

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background Influenza remains a significant yet under‐prioritized public health challenge in Africa, where unique hurdles such as limited surveillance, variable seasonal patterns, and under‐resourced health systems constrain effective prevention and control. This commentary provides a detailed analysis of the influenza landscape, with a focused

From Heterogeneity to Plasticity: Endothelial Dynamics in Lung Disease

Pulmonary Circulation, Volume 16, Issue 2, June 2026.
ABSTRACT Endothelial heterogeneity and plasticity play an important role in lung development, homeostasis, and pathology. In recent years, increasing evidence has demonstrated that endothelial dysfunction contributes to the progression of various lung diseases, such as ADRS, PF, PH, and lung developmental disorders.

Respiratory and systematic humoral and cellular immune response of pigs to a heterosubtypic influenza A virus infection [PDF]

, 2001
The level of heterosubtypic immunity (Het-I) and the immune mechanisms stimulated by a heterosubtypic influenza virus infection were investigated in pigs. Pigs are natural hosts for influenza virus and, like humans, they host both subtypes H1N1 and H3N2.

Development of a C5‐Azidoacetamide‐Modified 4‐Amino‐2,3‐Difluorosialic Acid Activity‐Based Probe for Labeling of Influenza A Neuraminidases

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
We report DFSA5Az/DFSA5bio, C5‐azidoacetamide 4‐amino‐2,3‐difluorosialic acid activity‐based probes that trap influenza A viral (IAV) neuraminidases (NA) via a stabilized covalent Tyr‐sialosyl intermediate with hour‐scale reactivation. A bioorthogonal azide enables CuAAC (or one‐step biotin) tagging for activity‐dependent Western‐blot detection at ...

The post-2009 influenza pandemic era : time to revisit antibody immunodominance [PDF]

, 2018
The current inactivated influenza vaccines rely on the induction of neutralizing antibodies against the head domain of the viral hemagglutinin (HA). The HA head contains five immunodominant antigenic sites, all of which are subject to antigenic drift ...

DNA Nanostructure‐Templated Multivalency Enables Broad‐Spectrum Virus Inhibition

Advanced Science, Volume 13, Issue 14, 9 March 2026.
A honeycomb‐shaped DNA nanostructure is introduced that organizes nanobodies or aptamers into trimeric clusters mirroring the native hemagglutinin arrangement on influenza viruses. This geometry‐matched multivalency enhances binding avidity by up to 1000‐fold, resulting in robust, broad‐spectrum viral neutralization and a 30–55% improvement in host ...

Influenza A and B viruses in the population of Vojvodina, Serbia [PDF]

, 2014
At present, two influenza A viruses, H1N1pdm09 and H3N2, along with influenza B virus co-circulate in the human population, causing endemic and seasonal epidemic acute febrile respiratory infections, sometimes with life-threatening complications.
