Researchers at Harvard’s Wyss Institute and Dana-Farber Cancer Institute report that a DNA origami-based vaccine platform called DoriVac generated robust immune responses in mice and in a human lymph node “Organ Chip” model. The team says the approach could be easier to store and manufacture than lipid nanoparticle–delivered mRNA vaccines, though the work remains preclinical. The results were published in Nature Biomedical Engineering.

Severe COVID or flu may raise lung cancer risk years later

New research indicates that severe cases of COVID-19 or influenza can alter lung immune cells, potentially increasing cancer risk months or years afterward. The study, conducted by scientists at the University of Virginia, highlights the role of chronic inflammation in this process and emphasizes vaccination as a preventive measure. Findings suggest closer monitoring for affected patients to enable early detection.

Stanford scientists develop universal nasal spray vaccine

23 febbraio 2026 Riportato dall'IA

Researchers at Stanford Medicine have created an experimental nasal spray vaccine that protects mice against multiple respiratory threats, including COVID-19, flu, bacterial pneumonia, and allergens. The vaccine activates the lungs' innate immune system for months, offering broad defense without targeting specific pathogens. Published in Science on February 19, the study suggests potential for human trials soon.

Flu experiment shows no transmission in shared hotel room

In a unique study, influenza-infected college students shared a hotel room with healthy middle-aged volunteers for two weeks, yet no infections occurred. Researchers attribute this to limited coughing, good ventilation, and participants' age. The findings underscore the role of airflow and masks in preventing flu spread.

Scientists discover migrions that accelerate viral infections

06 gennaio 2026 Riportato dall'IA

Researchers have identified migrions, virus-like structures that enable faster and more severe viral spread by hijacking cell movement. These packages, formed in migrating cells infected with vesicular stomatitis virus, deliver multiple viral genomes simultaneously to new cells. The discovery challenges traditional models of infection and highlights increased disease potential in animal tests.

Vaccino nasale sperimentale blocca trasmissione pertosse in trial

Un vaccino nasale sperimentale ha per la prima volta impedito la colonizzazione del batterio della pertosse negli umani, secondo un trial clinico recentemente pubblicato. Questa svolta potrebbe frenare la diffusione della malattia, in particolare in un anno di casi record in Inghilterra. Il vaccino BPZE1, sviluppato da ILiAD Biotechnologies, ha ridotto la presenza batterica di oltre il 97% rispetto al placebo.

Researchers map yellow fever virus in 3D, revealing key structural differences between strains

27 novembre 2025 Riportato dall'IA Verificato

Scientists at the University of Queensland have captured the first near‑atomic, high‑resolution 3D images of the yellow fever virus, detailing how the surface of the long‑used vaccine strain differs from virulent, disease‑causing strains. The work sheds light on how the virus is recognised by the immune system and could support improved vaccines for yellow fever and related mosquito‑borne diseases.
