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

University of Maryland School of Medicine (UMSOM) researchers helped conduct an important new global health study that found a vaccine that protects against five strains of meningitis prevalent in sub-Saharan Africa is safe and effective […]

University of Leeds researchers have taken a major step towards producing a more affordable and lower-risk polio vaccine using virus-like particles (VLPs). These particles mimic the outer protein shell of poliovirus, but are empty inside. […]
