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 […]

Gut microbiota may be the key factor explaining why certain individuals do not respond well to the pneumococcal vaccine, a bacterium that can cause various diseases, such as pneumonia. This conclusion is drawn from a […]

A new study published in The Lancet HIV reveals gaps in knowledge surrounding the prevention of HPV-related cancers in people living with HIV and outlines future research priorities.This post was originally published on this site
