NewsIn mice, viruses gain virulence in some individuals, depending on genetics and sex
New research demonstrates that some hosts appear to serve as “evolutionary accelerators” that could enable viruses to gain virulence more quickly.

NewsStudy confirms effectiveness of medicinal plant against SARS-CoV-2 virus
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus that causes COVID-19.

NewsYour nose is a battlefield
Scientists have discovered that FluMist can trigger an immune response directly in nasal tissue in adults. The vaccine trains immune cells in the upper nasal passages to recognize and fight influenza virus infection. This immune response stays in the upper airways and can’t be detected via blood samples.

NewsNew study shows antibodies need a strong core — not just grip — to fight SARS-CoV-2
Researchers used advanced computer simulations to investigate how antibody–virus complexes respond to mechanical forces across multiple SARS-CoV-2 variants, including the original 2019 strain and Omicron subvariants BA.4 and JN.1.

NewsVaccine strategy induces broadly neutralising HIV antibodies
Researchers have developed a new vaccine strategy that has generated antibodies capable of neutralising highly divergent HIV variants. The study provides new insights into how the immune system can be guided towards a particularly protected part of the virus.

NewsNew study suggests seasonal flu vaccines may reduce severity of H5N1 bird flu infections
Researchers have found that seasonal influenza vaccines in routine global use may significantly reduce the risk of death from H5N1 infection. The findings that readily available tools may offer protection while the world races to develop more targeted solutions.

NewsPlasmodium uses its own PI3K to suppress eat-me signal and evade host immune clearance
A study finds that Plasmodium PI3K actively suppresses the externalization of phosphatidylserine on the surface of infected erythrocytes. When the activity of parasite PI3K was chemically inhibited or genetically disrupted, phosphatidylserine exposure on infected red blood cells increased markedly.

NewsHow the immune system battles lifelong viral infections acquired at birth
Millions of people worldwide carry viral infections they acquired at birth, often for life. For a long time it was assumed that the immune system hardly fights these pathogens. Researchers show that the body’s defenses do indeed act against the virus.

NewsNew study suggests reduced newborn hepatitis B vaccination coverage may increase infant infections
Researchers found that lower vaccination coverage among infants born to unscreened mothers was associated with a substantial increase in HBV infections.
-
NewsResearchers discover new mosquito-specific viruses
A new study looked at mosquitoes’ immune response to discover many more insect viruses. Researchers hope to someday use the mosquitoes’ own immune system to battle some of the most pervasive and antagonistic human viruses.
-
NewsImmune cells in the nose slow influenza virus
Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may help protect against more severe illness, according to a study that may help guide the development of better influenza vaccines.

NewsAssociation of changes in portal insulin with immunometabolism during and after hepatitis C virus infection
A new study aims to investigate the relationship between insulin, the gut-liver axis, and immunometabolic changes in patients with hepatitis C virus. Lower portal insulin during HCVi is associated with changes consistent with altered pancreatic insulin secretion and decreased hepatic insulin extraction.

NewsSeparating signal from noise: How African biostatisticians are reshaping the fight against malaria
Biostatistics is unlocking smarter malaria solutions, linking parasite diversity, vaccines, and human behaviour to drive more effective prevention and protection.

NewsScientists highlight the cost of delaying childhood vaccination
Delaying hepatitis B vaccination after birth increases infections among newborns and decreases their survival rates and quality of life. A new study found that the longer the delay, the higher the cost in human life and health care.

NewsResearchers deploy phage therapy in new frontier against antimicrobial resistant infectious diseases
A revelatory treatment for patients with life-threatening infectious diseases is being pioneered in Melbourne. VICPhage, a clinical partnership between The Alfred and Monash, is one of the first in Australia to offer end-to-end capacity in phage therapy to treat some of the most challenging infections.

NewsGut microbiota impacts resistance to bacterial pneumonia: Study
A gut-lung connection influences susceptibility to infection by Acinetobacter baumannii, according to a new study. Investigators found that antibiotics disrupt the gut microbiota, suppress protective immune system pathways in the lungs; and increase the severity of pneumonia.
-
NewsStudy of influenza D in human cells and tissue hints at spillover potential
The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows.
-
NewsResearchers develop promising new vaccine against H5N1 bird flu
Researchers have developed a vaccine approach that shows promise in protecting against highly pathogenic bird flu, demonstrating strong efficacy in both mice and cattle. In 2024, the virus spread to dairy cattle and subsequently caused illness in about 70 farm workers with close contact to infected animals.

NewsNew study examines measles vaccination coverage after a postelimination outbreak
In 2022–2023, a large postelimination measles outbreak occurred in central Ohio. A study found that 20 months after the outbreak, MMR coverage across the entire primary care network (PCN) population remained well below herd immunity levels, with minimal gains.

NewsYellow food coloring changes gut microbiome in early life
Researchers found that the gut microbiotaof young rats changed with exposure to acceptable daily intake levels of the food coloring tartrazine. The males showed increases in bacteria linked to low-grade inflammation and they also did not gain as much weight as was expected.
