• Superspreader events trigger emergence of novel SARS-CoV-2 variants in USA

    10 days ago - By News Medical

    A team of scientists from the USA and Germany has recently studied the evolution of SARS-CoV-2 in a representative set of sequences from the USA collected between 2020 and 2021. The findings reveal that the viral genome has accumulated multiple mutations over time with only occasional loss of mutation. The main driving forces behind such genetic variations include widespread infection and superspreader events.

  • Study profiles the nose to predict immune response during COVID-19

    10 days ago - By News Medical

    SARS-CoV-2 resides in mucous membranes, making it easy to detect viral load in the nasal cavities. An international group of researchers has characterized the immunological and diagnosis characteristics of patients who may have or are confirmed with SARS-CoV-2 infection. The team found a distinct nasal cytokine profile that could help identify patients at risk for high inflammatory responses to SARS-CoV-2 infection.

  • Some SARS-CoV-2 variants evade mRNA vaccine-induced humoral immune, says study

    10 days ago - By News Medical

    Understanding how variants escape vaccine-boosted immune function is necessary to neutralizing SARS-CoV-2. An international team of researchers from MIT and Harvard University in the USA analyzed Pfizer and Moderna vaccines' effectiveness in neutralizing spike proteins from 10 different strains of SARS-CoV-2.
