Scripps researchers reveal HIV and Ebola weak spots using nanodiscs

Scientists at Scripps Research have developed a nanodisc platform that mimics viral membranes, uncovering hidden interactions in HIV and Ebola proteins that traditional methods miss. The technology allows for more accurate study of antibody responses, potentially accelerating vaccine development. The findings appear in Nature Communications.

Scientists uncover cause of rare COVID vaccine blood clots

April 11, 2026 Reported by AI

Researchers led by Flinders University have identified the molecular trigger behind a rare blood clotting disorder linked to adenovirus-based COVID-19 vaccines and infections. The immune system mistakes an adenovirus protein for the human blood protein PF4, leading to harmful antibodies in extremely rare cases. The discovery, detailed in the New England Journal of Medicine, paves the way for safer vaccines.

Stanford scientists develop universal nasal spray vaccine

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.

Northwestern reengineers HPV vaccine to boost T cell attack on tumors

February 18, 2026 Reported by AI

Researchers at Northwestern University have developed a more effective therapeutic vaccine for HPV-related cancers by rearranging components in a DNA-based nanoparticle. This structural adjustment significantly enhances the immune system's ability to target and destroy tumors. The findings, published in Science Advances, highlight the importance of molecular arrangement in vaccine design.
