NewsGrowing body of evidence links HPV with heart disease
In addition to causing several types of cancer, human papillomavirus (HPV) appears to bring a significantly increased risk of heart disease and coronary artery disease, according to a study.

NewsNewer hepatitis B vaccine shows promise as booster for health care workers
A new study compares the effectiveness of Heplisav-B, a new hepatitis vaccine, vs. standard hepatitis B vaccines as a booster in previously vaccinated individuals.

NewsEvaluating DNA impurities in recombinant adeno-associated virus
A new study indicates that DNA impurities derived from plasmid and host cell DNA are encapsulated into recombinant adeno-associated virus (rAAV) capsids as single-stranded DNA.

NewsNew study reveals a safer alternative for long-term hepatitis B treatment
Researchers have studied the effects of switching from long-term tenofovir disoproxil fumarate to the antiviral besifovir dipivoxil maleatein (BSV) in patients with chronic hepatitis B. Switching to BSV may improve patient kidney and bone health.

NewsStudy evaluates airborne transmission risk of mpox compared to COVID-19 and smallpox
Scientists have found that the inhaled infectious dose of mpox is at least 100 times lower than that of SARS-CoV-2 and smallpox, making efficient respiratory aerosol transmission highly unlikely in its current form - but future viral evolution could alter this dynamic.

News‘Low-sugar’ vaccine can provide broad immunity against coronavirus variants
A universal vaccine for coronaviruses removes sugar molecules from an area of a coronavirus spike protein that rarely mutates and creates effective and plentiful antibodies to inactivate the virus.

NewsUKHSA highlights pathogens of greatest risk to public health in bid to boost preparedness
The UK Health Security Agency (UKHSA) has today published its view on the pathogen families that could pose the greatest risk to public health, in a bid to focus and guide preparedness efforts against these threats.

NewsScientists ID natural products targeting SARS-CoV-2 - including caffeine
Researchers used computational methods to identify potential inhibitors of SARS-CoV-2 spike proteins, revealing promising natural compounds for guiding antiviral drug development, including caffeine.

NewsNew study sheds light on how bacteria ‘vaccinate’ themselves with genetic material from dormant viruses
Scientists have gained understanding on how bacteria defend themselves from phages, through gaining “memories” from predecessor dormant phages. The study will inform new phage therapies for bacterial infections that confer resistance to antibiotics.

NewsSimulation model shows potential affordability of preventative HIV therapy for infants
A type of cost-effective HIV neutralizing antibodies was evaluated to prevent the viral infection in infants during breastfeeding in high HIV prevalance countries. This treatment option is comparatively cheaper and has high clinical impacts in high HIV burden settings to achieve global elimination.

NewsMovie reveals DNA unzipping mechanism with implications for viral and cancer treatments
A detailed unwinding mechanism of the double-stranded DNA has been uncovered for the first time using cutting-edge technology, revealing how cells begin the crucial process of copying their genetic material.

NewsInfluenza of avian origin confirmed in a sheep in Yorkshire
The UK’s Chief Veterinary Officer has confirmed a case of influenza of avian origin (H5N1) in a single sheep in Yorkshire following repeat positive milk testing.

NewsNature’s warriors: How rice plants detect and defend against viral invaders
A groundbreaking study uncovers a molecular mechanism by which rice cells perceive viral infections and initiate antiviral response, which significantly contributes to understanding of virus-host interactions for further disease resistance breeding.

NewsMcMaster leads Canada’s first-ever guidelines for Post COVID-19 Condition
A team of experts from McMaster University has led the creation of Canada’s first-ever comprehensive guidelines for diagnosing, managing, preventing, and treating post COVID-19 condition (PCC), more commonly known as long COVID.

NewsH5N1 influenza viral lineages beginning to evade human immunological defenses
A new computer modelling approach predicts the protein-antibody interactions of the potentially pandemic-causing H5N1 avian influenza virus lineage. It helps to understand the viral evolution to ensure high vaccine efficacy.

NewsStudy identifies viruses in red tide blooms for the first time
A new study identifies viruses associated with Karenia brevis, the single-celled organism that causes red tide. By testing water samples collected from red tide blooms, the researchers found several viruses in blooms — including one new viral species.

NewsStudy yields new data on Mpox vaccine effectiveness in people with HIV
A new study has found that a single dose of the Imvanex vaccine provides protection against Mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, especially people with HIV, should receive the second dose of the vaccine as recommended.

NewsImmature platelet fraction offers clinical predictor for enhanced platelet recovery in patients with dengue fever
Immature platelet fraction (IPF) is recognized as a marker for thrombopoiesis, but a new study indicates that IPF% can be utilized as a predictor of platelet increase in patients with dengue infection.

NewsTunnel-building virus: How Zika transmits from mother to fetus
For the first time, researchers demonstrated the component involved in the tunneling nanotubes built by Zika virus to infect placental cells, an infection mechanism which is unique to the Zika virus alone.

NewsCurrent antivirals likely less effective against severe infection caused by bird flu virus in cows’ milk
Scientists found that in a preclinical model, two FDA–approved flu antivirals generally did not successfully treat severe H5N1 infections. Meanwhile, the route of infection, whether through the eye, the nose or the mouth, significantly impacts effectiveness.
