    Maternal COVID-19 vaccination may protect breastfeeding infants

    Women vaccinated against COVID-19 produced “robust” levels of anti-SARS-CoV-2-specific antibodies in breast milk samples for 6 weeks after vaccination, according to a study of dozens of breastfeeding women in Israel.
    “Antibodies found in breast milk of these women showed strong neutralizing effects, suggesting a potential protective effect against infection in the infant,” Sivan Haia Perl, MD, of the Pulmonary Institute at the Shamir Medical Center in Zerifin, Israel, and colleagues wrote in JAMA.
    The researchers prospectively analyzed 504 samples of breast milk from 84

  • Mask's fit may determine how well it protects against COVID-19

    Mask's fit may determine how well it protects against COVID-19

    25 days ago - By Healio

    Researchers found that wearing a medical procedure mask snugly beneath a cloth mask nearly doubled the effectiveness of filtering out particles the size of SARS-CoV-2, compared with wearing just one mask.
    They said the elimination of any gaps - rather than simply adding layers of materials - is the reason this approach works better.
    The CDC has previously recommended double masking to protect against COVID-19. However, the study that led to that conclusion was “limited” in the types and combinations of masks that were tested, according to Emily Sickbert-Bennett, PhD,

  • Researchers develop computational model to predict changes in SARS-CoV-2's viral fitness

    25 days ago - By News Medical

    Two researchers from the Université Libre de Bruxelles in Belgium, Fabrizio Pucci and Marianne Rooman, recently built a simplified computational model, called SpikePro, to predict the SARS-CoV-2 fitness from the amino acid sequence and structure of the spike protein. This study focuses on the spike protein's stability and the binding affinity to the host receptor.
