NewsTwo-dose recombinant shingles vaccine is effective even accounting for prior receipt of live shingles vaccine
A target trial emulation was conducted to assess the effectiveness of recombinant zoster vaccine (RZV) accounting for prior receipt of live zoster vaccine (ZVL) and immunocompetence. The results suggest individuals vaccinated with ZVL should be revaccinated with two doses of RZV.

NewsStudy finds HEPA purifiers alone may not be enough to reduce viral exposure in schools
In a secondary analysis of a study of 200 classrooms, researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed.

NewsProtein nanorings designed to detect and neutralize SARS-CoV2 virus
Scientists have generated a new ring-shaped protein nanomaterial capable of strongly binding to and neutralising the SARS-CoV2 virus. The new nanomaterial is formed by a scaffold based on recombinant ring-like proteins (RLPs), to which mini proteins were incorporated.

NewsIn a nasal spray, gold nanoparticles deliver a targeted treatment to the brain
In the form of a ‘nasal spray’, tiny gold particles act as carriers, delivering a treatment directly to the brain: a new nanotechnological device for the treatment and prevention of neuropsychiatric and neurodegenerative diseases and infections.

NewsResearch team with the latest Nobel Prize laureate reveals regulatory immune cell precursors disrupted in severe COVID-19
A research team joined by Professor Shimon Sakaguchi – the latest Nobel Laureate in Physiology or Medicine – has identified a subset of immune cells called precursor T follicular regulatory cells (preTfr) that play a critical role in preventing autoantibody production.

NewsResearchers find key to stopping deadly infection
New research has identified a key step that enables rotavirus to infect cells. The researchers found that disabling the process in tissue culture and in mice prevented infection.

NewsDo imported cut flowers spread livestock viruses?
A study investigated whether Culicoides biting midges are being accidentally exported from Africa to Europe in shipments of cut flowers. Although researchers did detect small numbers of these insects near and inside greenhouses on a Kenyan flower farm, they found none in packaging or transport areas.

NewsNew study reveals where HIV hides in different parts of the body
A new study reveals that HIV cloaks itself in the DNA of infected cells using unique DNA patterns in the brain, blood and parts of the digestive tract. For example, in the brain, the virus avoids genes and hides in less active parts of the DNA.

NewsScientists blaze new path to fighting viral diseases
Scientists have identified a potential new drug against the virus that causes COVID-19 - and devised a powerful new platform for finding medicines to fight many types of infectious diseases. Compound 6, led SARS-CoV-2 viral proteins to misfold, malfunction, and ultimately, be destroyed and removed by cells, in lab tests.

NewsAntibody discovered that blocks almost all known HIV variants in neutralization assays
An international research team has discovered an antibody that could advance the fight against HIV. The newly identified antibody 04_A06 proved to be particularly effective in laboratory tests. It was able to neutralize 98.5 percent of more than 300 different HIV strains, making it one of the broadest antibodies against HIV identified.

NewsResearch reveals fetuses exposed to Zika virus have long-term immune challenges
Researchers discovered that when a pregnant mother is infected with Zika virus, the resulting inflammatory response in the placenta permanently changes how the offspring’s immune system develops - even if the infection is mild or asymptomatic in the mother.

NewsLong Ebola: Sudan virus can persist in survivors for months, study shows
More than half of survivors of the Sudan Ebola virus still suffer serious health problems two years post-infection and the virus can persist in semen and breast milk for months after recovery, according to the first study examining the virus’s long-term effects.

NewsSpotlight on phage for a fascinating policy discussion
Scientists turned the spotlight onto the potential of phage in a recent AMI webinar that yielded a fascinating in-depth discussion that proved invaluable in clarifying the way forward. The ‘Phages for a Sustainable Future’ webinar has now been released as a video.

NewsScientists explore how viruses replicate and infect
Herpes viruses cultivated using one kind of host cell – known as a producer cell – exhibited differences from the same virus cultivated with a different producer cell.

NewsViruses help cut farm greenhouse gas emissions by targeting soil microbes
A new study reveals that soil viruses can reduce nitrous oxide (N2O) emissions by selectively infecting the microbes responsible for producing this potent greenhouse gas.

NewsResearchers deconstruct chikungunya outbreaks to improve prediction and vaccine development
Researchers analyzed more than 80 outbreaks of chikungunya virus to improve prediction of future outbreaks and inform vaccine trial development.

NewsThe RESTART trial: a drug to block a toxic HIV molecule
What if the presence of a well-known but misunderstood viral protein explains why some people living with HIV (PLWH) never recover their health, even with antiretroviral treatment? Researchers will explore this in a groundbreaking clinical trial this fall.

NewsAI can be valuable tool to strengthen pandemic preparedness
Artificial intelligence could be a valuable tool for detecting emerging diseases earlier, researchers from five European universities and research institutes argue.

NewsSome human GII.4 norovirus are better than others at infecting cells; researchers have found out why
A study reveals that human GII.4 noroviruses have evolved a uniquely potent entry mechanism with clear strain-specific differences. The findings open new possibilities for identifying the elusive human norovirus receptor as well as developing vaccines and treatments.

NewsHeart rhythm disorder POTS common in patients with long COVID
A new study shows that an unusual heart rhythm disorder, POTS, is particularly common in people with long COVID. The majority of those affected are middle-aged women.
