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.

NewsWhere people get their news influences their beliefs about vaccines
People who follow “new right” media outlets are more than twice as likely to be vaccine-hesitant compared to those who never engage with those outlets, a new study finds. Hesitant adults were more likely to rely on non-authoritative sources for health information.

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.

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.

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.

NewsA universal toolkit for editing bacterial DNA
A major collaboration involving nine labs has transferred a particularly useful DNA editing system from E. coli into 14 new species of bacteria, spanning three major branches of the bacterial family tree.

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.

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.

NewsAmbient air pollution is associated with respiratory infection burden in the first year of life
Ambient air pollution is associated with respiratory infection burden in the first year of life, according to preliminary findings from the Immune Development in Early Life (IDEaL) Rome Cohort.

NewsDrip-irrigated halotolerant PGPB boost jujube yield and quality in saline soils by reshaping soil bacterial communities
A new study demonstrates that applying halotolerant plant growth-promoting bacteria (PGPB) via drip irrigation during the crop growth period can effectively alleviate soil salinity stress, enhance jujube productivity and fruit quality, and restructure rhizosphere bacterial communities in saline agricultural soils.

NewsCOVID-19 and severe heart attack increase mortality by 25% after one year, more than double pre-pandemic rates
Findings from the North American COVID-19 Myocardial Infarction (NACMI) registry demonstrate significantly higher one-year mortality rates in patients with COVID-19 and ST-elevation myocardial infarction (STEMI) compared to patients with STEMI alone.

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.

NewsTiny switch controls rare rotary machine in bacteria - and can even reverse direction of spin
Researchers have discovered a tiny molecular switch that can control and reverse the direction of a rare rotary machine linked to motility, surface colonization and protein secretion in bacteria.

NewsMen and women may differ in how fitness level Is linked to gut microbiome diversity
Aerobic fitness may be influenced by microbes in the gut, but men and women appear to show a different connection, according to a first-of-its-kind study.

OpinionReversing the threat: How to stop measles from spreading again
As the Global Virus Network issues a stark warning over the significant resurgence of measles in the US and globally, William J. Moss, Sten H. Vermund, and Maggie L. Bartlett set out what needs to be done if the preventable harms of the current surge are to be reversed.

NewsThat late-night snacking is probably messing up your gut
It’s well known that chronic stress can disrupt bowel function, sending people running to the bathroom or making them constipated. New research suggests that eating late at night amplifies these effects, with implications for both digestive health and the gut microbiome.

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.
