NewsInappropriate antibiotic use for COVID-19 is linked to resistance
Taking azithromycin for as little as one day triggers antibiotic resistance in the respiratory tract, according to a first-of-its kind look by scientists at the changes that occur in the microbiome of hospitalized patients who were treated for COVID-19.

NewsTrial finds vitamin D supplements don’t reduce Covid severity but could reduce long COVID risk
In a large, randomized trial, researchers have found that high-dose vitamin D3 did not reduce COVID-19 infection severity, but may impact long COVID outcomes.

NewsSevere COVID-19 and flu facilitate lung cancer months or years later, new research shows
Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease’s development, but vaccination heads off those harmful effects, new research indicates.

NewsBuilding protection against infectious diseases with nanostructured vaccines
Researchers have leveraged a recently developed highly versatile DNA origami nanotechnology that is both vaccine and adjuvant, named DoriVac, as an alternative to current vaccine platforms.

NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

News How viruses mess with our brains
What impact does a viral infection have on our memory, attention, and concentration? A new review has identified several biological markers associated with cognitive decline in the context of infection. It also provides a solid foundation for future research.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.

NewsDiffering immune responses in infants may explain increased severity of RSV over SARS-CoV-2
Reseachers report that the two respiratory viruses trigger different immune responses. Those differences might explain why these two diseases have different clinical outcomes and require different treatment strategies.

NewsCOVID-19 infection predicts higher risk of kidney disease, study finds
Researchers have found that previous COVID-19 infection is a significant risk factor for kidney disease. Compared to influenza, those with a history of COVID-19 infection have a 2.3-times higher risk of acute kidney injury and a 1.4-times higher risk of chronic kidney disease, according to an analysis of over three million patients.

NewsStudy reveals key differences in long-term brain effects of COVID-19 and flu
While both Covid and flu can leave lasting lung damage, only SARS-CoV-2 infection caused persistent brain inflammation and small blood vessel injury, even after the virus was no longer detectable, a new study has found.

NewsNew single-cell transcriptomic clock reveals intrinsic and systemic T cell aging in COVID-19 and HIV
Scientists developed a new single-cell transcriptomic clock called T immune cell transcriptomic clock (Tictock) to measure aging in specific immune cells. They found that in patients with acute Covid-19, the infection increased the biological age of naïve CD8 T cells.

NewsHoly Grail: One vaccine may provide broad protection against many respiratory infections and allergens
In a new study in mice, researchers have developed a universal vaccine formula that protects against a wide range of respiratory viruses, bacteria and even allergens.

NewsMissed opportunity: Study shows low vaccination rates among expectant mothers in Norway against COVID-19 and influenza
A study of over 50,000 pregnant women in Norway during the 2023/24 influenza season found that only 29.9% were vaccinated against influenza and 12.1% against COVID-19 during pregnancy, remaining far below recommended targets.

NewsBooster jabs reduce the risks of COVID-19 deaths, study finds
Booster vaccines reduced the risk of COVID‑19–related hospitalisation and death, according to a new study of over 3 million adults who had the autumn 2022 vaccine in England.
-
NewsCOVID-19 vaccination during pregnancy may help prevent preeclampsia
A new multinational study has found that COVID-19 vaccination during pregnancy, particularly when combined with a booster dose, significantly reduces the risk of preeclampsia, a serious and potentially life-threatening pregnancy complication.
-
NewsChildren with sleep apnea face higher risk of flu and COVID-19, new study finds
A five-year study has revealed that children with sleep apnea are twice as likely to contract the flu or COVID-19, regardless of their age or weight. Even after undergoing surgery to remove tonsils or adenoids, this increased vulnerability persists due to long-term changes in the immune system.

CareersSummer Studentship: novel antivirals and host-virus interactions
Jessica Harris reports back on her Summer Studentship at De Montfort University, and her research into how plant-derived compounds affect viruses, and whether combining these antivirals might increase viral inhibition.

NewsNo association between mRNA COVID-19 vaccination during pregnancy and autism in children, new research shows
The mRNA COVID-19 vaccine is not associated with autism or other neurodevelopmental problems in children whose mothers received the vaccine immediately before or during pregnancy, according to new research.

NewsLong COVID linked to Alzheimer’s disease mechanisms
The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer’s disease and greater levels of dementia, a new study finds.

NewsDiscovery of SARS-CoV-2 PLpro inhibitors and RIPK1 inhibitors with synergistic antiviral efficacy in a mouse COVID-19 model
A new article publication discusses the discovery of SARS-CoV-2 PLpro inhibitors and RIPK1 inhibitors with synergistic antiviral efficacy in a mouse COVID-19 model.
