NewsGlobal Virus Network statement on H5N1 vaccine developments
The new vaccine momentum reflects the growing urgency of avian influenza (H5N1) threat and reinforces the need for coordinated global preparedness.

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.

NewsNew cellular target prevents hepatitis E infection
To replicate, a virus must first enter a host cell. In a recent study, the researchers specifically investigated host cell processes required for successful HEV infection. In doing so, they identified the enzyme PIKfyve as a crucial factor for viral entry.

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.

NewsHow AI can help us count the ‘good’ viruses used in biopharmaceuticals
Researchers have developed a new methodology that uses artificial intelligence (AI) tools to identify and count target viruses more efficiently than previous techniques. The new approach can be used in applications such as pharmaceutical biomanufacturing.

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.

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.
-
NewsEight-year results from two randomized phase 3 trials of tenofovir alafenamide for chronic hepatitis B virus infection in China
Tenofovir alafenamide (TAF) has demonstrated comparable efficacy to tenofovir disoproxil fumarate (TDF), with improved renal and bone safety, in Chinese participants with chronic hepatitis B enrolled in two Phase 3 trials.

NewsSARS-CoV-2 does not persist in the placenta after maternal recovery from COVID-19
A new study finds that the virus that causes COVID-19 does not linger in placental tissue weeks to months after a pregnant woman recovers from infection - offering important reassurance for clinicians and patients alike.

NewsCOVID antiviral speeds recovery but doesn’t reduce hospitalization in vaccinated patients, trials find
Paxlovid (nirmatrelvir-ritonavir) does not reduce hospital admissions or deaths in vaccinated adults at higher risk of severe COVID-19, despite helping them recover faster, according to results from two national trials.

NewsScientists find a new way coronaviruses can get into human cells
An international team of researchers has identified an East African bat coronavirus capable of entering human cells. Whilst the virus can bind to a cell receptor found in the human lung, preliminary testing in Kenya suggests it has not spilled over into the local human population.

NewsResearchers fight oral cancer with bioengineered chewing gum
Research shows that antiviral and antibacterial chewing gums reduce the levels of three microbes linked to worse outcomes in oral cancers, paving the way for more effective and affordable therapies.
-
NewsNew clues to hepatitis B species restriction could help build a novel model for studying infection and testing therapies
For decades, it was thought that the barrier to creating a workable mouse model for hepatitis B is an inability for the virus to gain a genetic foothold in the mouse due to its unique type of DNA. Now researchers have discovered that the problem is something different altogether—likely a misstep in the entry process.

NewsWHO certifies the Bahamas for eliminating mother-to-child transmission of HIV
In a landmark achievement for Caribbean public health, the World Health Organization (WHO) congratulates The Bahamas for becoming the latest Caribbean nation to be certified as having eliminated the mother-to-child transmission of HIV.

NewsFlu vaccine no longer required for U.S. military
The U.S. military is ending its long-standing requirement that service members receive the annual flu shot, a decision announced by Defense Secretary Pete Hegseth.

NewsRising measles cases highlight gaps in vaccination coverage and public health system vulnerabilities
The Global Virus Network (GVN) is closely monitoring a significant resurgence of measles in the United States and globally, reflecting a growing vulnerability in public health systems.

NewsEarly immune responses linked to protective HIV antibodies
In a new study of broadly neutralizing antibodies and their potential for an HIV vaccine, researchers analyzed fragments of cell-free RNA and DNA circulating in the blood. This makes it possible to track immune responses, viral genetic variation, and other microbes from the same blood sample.
