NewsHIV vaccines tested in PrEPVacc fail to reduce infections
The results of the PrEPVacc HIV vaccine trial conducted in Eastern and Southern Africa, which ran between 2020 and 2024, show that neither of the two experimental vaccine regimens tested reduced HIV infections among the study population.

NewsNew drug target identified for diseases associated with leukemia-causing virus
Researchers have found a new target for treating diseases associated with human T-cell leukemia virus type 1 (HTLV-1). Blocking kinases, which regulate cellular functions, leads to cell death caused by the degradation of the protein Tax.

NewsResearchers expose the rules behind dengue’s invasion strategies
Scientists uncover fundamental rules for how dengue virus infects its mosquito and human hosts, providing hope for identifying therapeutic approaches.

NewsMutations of the spike gene do not predict the severity of variants of SARS-CoV-2
The two recent and prevalent strains of the virus that cause COVID-19 are not significantly better than their predecessor Omicron at evading immune responses and causing infections despite having a higher number of mutations.
-
NewsScientists investigate effectiveness of non-pharmaceutical interventions against pathogens
Scientists have investigated the success of non-pharmaceutical interventions, analysing almost two million SARS-CoV-2 genomes that occurred in the German population during the years of the pandemic.

NewsScientists pinpoint new drug target for RSV
Scientists have discovered how the dangerous Respiratory Syncytial Virus (RSV) defuses our immune response and, in doing so, they have pinpointed an exciting new target for drug developers.
-
NewsResearchers unveil secrets behind phages’ flawless timing
New research is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena.

NewsStudy identifies unpredicted immune responses to adenoviral COVID vaccines
Researchers have identified unpredicted T-cell immune responses to the adenoviral (Oxford/AstraZeneca and Janssen) COVID-19 vaccines, but not to the mRNA vaccines.

NewsWastewater could yield thousands of novel viruses, study reveals
Deep metagenomic sequencing of wastewater in Berlin over 17 months shows this technique could help forecast disease outbreaks and monitor the spread of human pathogens. It can also reveal thousands of novel viruses, a new study reveals.
-
NewsStudy shows promise for a universal influenza vaccine
New research reveals a promising approach to developing a universal influenza vaccine — a so-called “one and done” vaccine that confers lifetime immunity against an evolving virus.

NewsLlama nanobodies deliver breakthrough in building HIV immunity
Scientists have developed a new antibody therapy that can neutralize a wide variety of HIV-1 strains. They found success in an unlikely source — llamas.
-
NewsInfluenza viruses can use two ways to infect cells, study finds
Scientists have discovered that certain human flu viruses and avian flu viruses can use a second entry pathway, a protein complex of the immune system, to infect cells, helping the viruses to infect different species.
