NewsQdenga vaccine shows effectiveness against dengue under real-world conditions during Brazil’s 2024 outbreak
An international team of researchers has demonstrated that the tetravalent dengue vaccine Qdenga provides significant protection against the disease under real-world conditions, during the large 2024 epidemic in São Paulo, Brazil.

NewsPotential biomarker for the development of long COVID identified
A research team has demonstrated that a specific component of the immune system (PTX-3) remains at significantly higher levels in the blood of patients who have suffered from severe COVID-19, even months after the acute infection has subsided.

NewsRisk of long COVID in kids doubles after second infection
Children and adolescents were twice as likely to experience long COVID after catching COVID for the second time, compared to their peers with a single previous infection, results running counter to the popular perceptions that COVID in children is ‘mild’.

NewsResearchers uncover HIV mystery that could unlock the path to a cure
Researchers have identified for the first time how HIV enters a dormant state in infected cells that allows the virus to “hide” from the immune system and current treatments. HIV orchestrates its own survival by reprogramming host cells to create the perfect hiding place.

NewsFungal toxin offers colonization support - in small doses
The yeast fungus Candida albicans not only uses the toxin candidalysin to cause infections, but also to colonize the oral mucosa inconspicuously – but only in finely balanced amounts. Too little toxin prevents oral colonization, too much triggers the immune system.

NewsInactive H5N1 influenza virus in pasteurized milk poses minimal health risks
Proteins and genetic material from H5N1 influenza viruses have been found in pasteurized milk in the United States, but a study shows those inactive viral pieces represent little to no health risk. H5N1-contaminated milk that was pasteurized did not significantly affect the immune system.

NewsMeta-analysis: COVID-19 vaccination during pregnancy is safe and beneficial for mother and infant
Vaccination is associated with better neonatal outcomes without added maternal risk, according to research presented during the American Academy of Pediatrics 2025 National Conference & Exhibition.

NewsIn pregnant mice with severe flu, harmful molecules can breach fetal barriers
A new study shows, for the first time, that severe flu infection in pregnant mice leads to a breakdown in placental and brain barriers, leading to the accumulation of potentially harmful molecules in the fetal brain. Fibrinogen can pass into developing fetal brains.

News NIH grant to UC Riverside supports research on dangerous emerging virus
Researchers have been awarded an NIH grant of about $3.4 million over five years to lead an international study focused on developing protective antibodies against Crimean-Congo hemorrhagic fever virus (CCHFV), a biosafety level 4 pathogen and a Category A bioterrorism agent.

NewsNew single-dose, temperature-stable rabies vaccines could expand global access
Researchers have discovered a new way to make human rabies vaccines that could greatly expand access to immunization across the globe. The new method creates shots that are temperature-stable—meaning they don’t need to be stored at cold temperatures.

NewsGut punch: $2 million to decode bacteria’s role in fighting disease
A $2 million grant to UC Riverside will explore how gut bacteria shape human health. The NIH award will support Ansel Hsiao’s lab in its quest to answer questions about how gut microbes communicate with each other and with their human hosts to influence health.

NewsEngineered gut bacteria improves survival outcomes in colorectal cancer tumors
A genetically modified Salmonella typhimurium strain can colonise tumours and release a therapeutic protein, LIGHT, to induce the formation of mature tertiary lymphoid structures (mTLSs) in laboratory models.

NewsKoala stress linked to virus infection risk
Researchers have revealed a clear relationship between stress and increased disease risk in koalas in South East Queensland and on the New South Wales North Coast.The study tracked the level of koala retrovirus (KoRV) in groups of captive and wild koalas.

NewsYeast in gut microbiome can worsen salmonella infection
Researchers have discovered that a yeast commonly found in our gut can make infection with salmonella worse. Salmonella binds to Candida albicans and triggers a chain reaction that allows the bacteria to better invade cells lining the intestines.

NewsCattle vaccine immunity ‘boost’ tested by new research
Scientists at Aberystwyth University are leading research into how a widely used vaccine can boost overall immunity in livestock. The four-year study will investigate the concept of ‘trained immunity’ – a form of immune memory triggered by a vaccine.

NewsFood additives in pregnancy: effects on offspring microbiota increase susceptibility to inflammatory diseases
A study conducted in mice reveals that maternal consumption of dietary emulsifiers can have a negative impact on the gut microbiota of their offspring and may increase their risk of developing chronic inflammatory gut disorders and obesity in adulthood.

NewsNIH grant aims for childhood vaccine against HIV
A multi-institutional team led by Weill Cornell Medicine investigators has been awarded a five-year, $20.8 million grant from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, for advanced preclinical development of a promising experimental HIV vaccine.

NewsTuberculosis vulnerability of people with HIV: a viral protein implicated
Tuberculosis accounts for one in three deaths among people living with HIV. A new study highlights the key role played by Tat 2 – a viral protein secreted by HIV-infected cells – in this hyper-vulnerability phenomenon.

NewsAdverse event profiles following HPV vaccination in males
The safety profile among male recipients of human papillomavirus (HPV) vaccination remains a critical evidence gap. A new study presents the first systematic safety evaluation of Gardasil 9 and Gardasil in male recipients.

NewsScientists identify four ways our bodies respond to COVID-19 vaccines
Researchers tracked individuals’ antibody levels after vaccinations and identified four distinct patterns of immune response after the first booster, suggesting that monitoring how antibody levels change over time could assist in identifying individuals at greater risk of infection.
