High-dose flu shots inked to lower Alzheimer's dementia risk in older adults

A large US claims-based study found that adults aged 65 and older who received a high-dose flu vaccine had a lower observed risk of Alzheimer dementia than those who received a standard-dose vaccine, with the association lasting up to 25 months in per-protocol analyses and 28 months in intention-to-treat analyses. The signal appeared stronger and more sustained in women, though the authors stress that the findings are observational and need confirmation in longer prospective studies.

New drying technique stabilizes vital vaccines at room temperature

A significant challenge in global healthcare and biotechnology is the "cold chain"-the network of refrigerated storage and transport required to keep protein-based drugs, vaccines, and diagnostic tests from degrading.

Flu vaccine halves heart attack risk after breakthrough infection

Influenza vaccination could significantly reduce the risk of influenza-associated heart attack and stroke even among people who get infected after getting the vaccine, according to research just published in Eurosurveillance.

PCV schedule shift associated with increased vaccination inequalities in England

Vaccine uptake data has been examined to assess the impact of moving from a '2+1' to a '1+1' Pneumococcal Conjugate Vaccine (PCV) dose schedule on vaccine coverage and health inequalities among infants in England.

High-dose flu vaccine linked to lower Alzheimer’s disease risk

A UTHealth Houston physician's visit to a local public health building sparked community awareness and inspired a new research idea.

New therapy reprograms immune cells to reduce asthma inflammation

A collaborative effort between researchers at the Henan Academy of Innovations in Medical Science, Zhengzhou University, and Shenzhen University School of Medicine has provided the first proof-of-principle study demonstrating that targeting a receptor on the surface of anti-inflammatory regulatory T cells (Tregs) can restore their function and alleviate asthma in mice.

Rapid antiviral treatment reduces nursing home hospitalizations during flu outbreaks

In nursing homes, influenza spreads quickly. Even in facilities with separate wings, staff move throughout the home, caring for medically complex older adults who often share rooms.

New T cell mechanism could lead to longer-lasting vaccines

Researchers at the University of Wisconsin School of Veterinary Medicine have identified a possible way to make longer lasting vaccines for respiratory viruses like influenza and the coronavirus that causes COVID-19.

Natural peptide in sweat may help block flu infection before symptoms start

Researchers led by the Fisabio Foundation found that dermcidin, a natural antimicrobial peptide present in sweat and respiratory tissues, can block influenza infection by binding to a highly conserved region of the viral hemagglutinin protein and preventing cell entry. The study also found that people who did not develop flu-like symptoms had markedly higher baseline dermcidin levels, suggesting the molecule may help reduce susceptibility to infection and could support the development of broader-spectrum antivirals.

New clinical guideline adopts holistic approach to brain and heart health

A new brain–heart clinical practice guideline takes a holistic approach, integrating neurologic and mental health evidence with guidance for cardiovascular disease as many brain and heart conditions overlap and share similar risk factors.

Study opens the door for future treatments for Sleeping Sickness

To survive in the human bloodstream, the African trypanosome parasite wears a "cloak" made of proteins known as a variant surface glycoprotein (VSG).

Brain resilience peaks about an hour after stress exposure

Psychological resilience is often misunderstood as simple "toughness" or an insensitivity to stress. However, true resilience is the brain's capacity to adapt and recover after a stressful event.

Study explores airborne bird flu decay in livestock environments

Discovering how the bird flu virus degrades in the air around livestock and how engineering solutions can effect that degradation quickly and efficiently are core aims of a new University of Michigan Engineering-led project funded by the U.S. Department of Agriculture.

Aging lung cells drive severe inflammation in flu and COVID

Older adults are much more likely to become seriously ill from flu or COVID because aging lung cells can drive excessive immune responses, according to a new study led by researchers at UC San Francisco.

New study maps global immune gene diversity across multiple populations

Inherited variations in antibody genes can affect how we respond to infections and vaccines, show two new studies from Karolinska Institutet in Sweden, published in the journal Immunity.

The molecular mechanism that turns cool temps into nerve signals

When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" signal to your brain.

CDC tracks SARS-CoV-2 BA.3.2 global rise and finds early signals in U.S. wastewater

CDC surveillance shows that the highly divergent SARS-CoV-2 variant BA.3.2 spread to at least 23 countries and was detected in U.S. travelers, patients, airplane wastewater, and wastewater samples across multiple states. The report highlights wastewater and traveler-based genomic surveillance as early warning tools while noting that BA.3.2 has immune-evasion potential but has not rapidly displaced other circulating lineages.
