NewsLongest known SARS-CoV-2 infection of 613 days led to unique highly mutated variant
New research to be presented at next week’s ESCMID Global Congress highlights the risk of new immune-evasive SARS-CoV-2 variants emerging in immunocompromised patients.
-
NewsVaccine monitoring crucial as SARS-CoV-2 variants continue to evolve
Researchers compared the newer monovalent COVID vaccine, which specifically targets the XBB variant of Omicron, with older bivalent vaccines containing a mix of an Omicron variant and the original strain of COVID-19.
-
NewsCOVID vaccine during pregnancy improves neonatal outcomes
A study has found that neonates of booster-vaccinated mothers had less risk of being infected with COVID-19 compared to those of unvaccinated mothers. Neonates of unvaccinated mothers died twice as frequently as those of vaccinated mothers.
-
NewsHuman immune system evolves in the post-Omicron era
New research suggests that human immune responses are changing in order to combat the never-ending emergence of new SARS-CoV-2 variants.
-
NewsPirola variant of Covid rediscovers entry pathway into lung cells
Researchers have discovered that the Pirola variant enters lung cells with high efficiency and uses the cellular enzyme TMPRSS2 for entry, thereby exhibiting parallels to variants Alpha, Beta, Gamma and Delta.
-
NewsCOVID-19 vaccine strongly effective for children and adolescents during delta and omicron
Children and adolescents who received one of the main COVID-19 vaccines were significantly protected and showed no increased signs of cardiac complications compared to young people who were not vaccinated.
-
NewsSARS-CoV-2 BA.2.86 less resistant to vaccine, but may be a problem in the lung
New research shows that the recently emerged BA.2.86 omicron subvariant of the virus that causes COVID-19 can be neutralized by bivalent mRNA vaccine-induced antibodies in the blood.
-
NewsOmicron induces cellular senescence in human lung, study finds
Researchers investigating the influence of defined altered spike formations have confirmed that the Omicron variant induces cellular senescence in human lungs of COVID-19 patients.
-
NewsBroad-spectrum antiviral candidate targets dengue and SARS-CoV-2
A broad-spectrum antiviral drug candidate, 2-thiouridine, that targets positive-strand RNA viruses has been identified and characterized.
-
News Targeting a coronavirus ion channel could yield new Covid-19 drugs
Chemists discover the structures of open and closed states of the channel, which could help the development of antiviral drugs to reduce inflammation.
-
NewsVulnerability to different COVID-19 mutations depends on previous infections and vaccination
A person’s immune response to variants of SARS-CoV-2 depends on their previous exposure – and differences in the focus of immune responses will help scientists understand how to optimise vaccines in the future to provide broad protection.
-
NewsCOVID-19 could hold key to spotting viruses with pandemic potential
Certain SARS-CoV-2 variants of concern are evolving to do a better job of shutting down human innate immune responses, according to new research.
-
NewsStudy helps explain SARS-CoV-2 variants’ rapid spread
Omicron variants, which circulated quickly around the globe, bind to cells more avidly and evade antibodies more efficiently than earlier variants, new research reveals.
-
NewsFitness landscape explains Covid variant origins
Researchers have uncovered the mechanisms behind the emergence of new and dangerous coronavirus variants, such as Alpha, Delta, Omicron, and others.
-
NewsFirst human respiratory organoid culture system reveals secret of Omicron’s transmissibility
Researchers have established the first human respiratory organoid culture system and unveiled a novel mechanism for the high transmissibility of SARS-CoV-2 Omicron variant.
-
NewsOmicron appears more deadly than seasonal influenza, study suggests
Adults hospitalised with the SARS-CoV-2 Omicron variant have a higher death rate than those hospitalised with seasonal influenza, even though Omicron is considered less virulent with lower case fatality rates than the delta and alpha strains, new research being presented at ECCMID suggests.
-
NewsMask rule in hospitals may have little impact on COVID-19 transmission during Omicron wave
A study in large London hospital during first 10 months of Omicron activity suggests the real-world benefit of mask-wearing in isolation is likely to be modest, according to new research being presented at this year’s ECCMID.
-
NewsInexpensive way to produce anti-Covid nanobodies cuts down on the llamas
Researchers have come up with a less expensive way to isolate and identify nanobodies that target various parts of the SARS-CoV-2 spike protein and are currently derived from llamas.
-
NewsStudy shows New York City rats carry SARS-CoV-2
Wild rats in the New York City municipal sewer systems and elsewhere in the city have been exposed to SARS-CoV-, a new study has revealed.
-
NewsThree compounds from sea sponge and marine bacteria offer Covid-blocking powers
University of British Columbia researchers have identified three compounds that prevent COVID-19 infection in human cells, derived from natural sources including a BC sea sponge.
