The State Key Laboratory for Emerging Infectious Diseases at the University of Hong Kong (HKU) and the InnoHK Center for Virology, Vaccinology and Therapeutics (CVVT) have pioneered an influenza virus vector-based nasal spray vaccine platform […]

New research led by Yale School of Medicine (YSM) advances the goals of creating a diagnostic test and vaccines for tick-borne diseases. The study was published March 26 in Science Translational Medicine.This post was originally […]

An unusual public health policy in Wales may have produced the strongest evidence yet that a vaccine can reduce the risk of dementia. In a new study led by Stanford Medicine, researchers analyzing the health […]

Researchers at the University of Cologne and University Hospital Cologne have determined that the novel mRNA-based COVID-19 vaccines not only induce acquired immune responses such as antibody production, but also cause persistent epigenetic changes in […]

Sugar coatings aren’t only for candies; they also help viruses, like the ones that cause COVID-19, hide from their hosts’ immune system. Now, researchers have developed a universal vaccine that targets coronaviruses and the sugars […]

Adult antibody thresholds are currently used to determine whether immunocompromised children should get a measles, mumps, and rubella (MMR) booster shot. However, a new study shows that these thresholds fail to identify a significant percentage […]

Universitätsmedizin Berlin has found that a single dose of the Imvanex vaccine provides protection against mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. […]

Germinal centers are high-speed evolution machines. Tiny clusters in the lymph nodes, germinal centers refine antibodies through mutation and expansion until they produce high-affinity B cells adapted to keep different pathogens in check. But rapid […]

A vaccine’s ability to generate long-lasting, high-affinity antibodies hinges on a delicate balance. Upon exposure to a vaccine or pathogen, B cells scramble to refine their defenses, rapidly mutating in hopes of generating the most […]

New computational modeling of avian influenza variants’ immunoprotein interactions—developed by a research team at the University of North Carolina at Charlotte—reveals the H5N1 influenza virus is evolving to escape immunological defenses raised by previous infection […]
