This Viewpoint discusses physical and epidemiological evidence supporting droplet vs aerosol transmission of severe acute respiratory syndrome coronavirus 2 (SA
Nach ausführlicher Prüfung der präklinischen und klinischen Daten aus den Phase-1/2-Studien und in Absprache mit dem Center for Biologics Evaluation and Research (CBER) der US-Arzneimittelbehörde FDA und anderen globalen Regulierungsbehörden haben Pfizer und BioNTech beschlossen, einen Impfstoffkandidaten mit einer Dosis von 30 µg in einem 2-Dosis-Schema in die Phase-2/3-Studie zu bringen. Erst vor Kurzem hatte dieser Impfstoffkandidat den Fast-Track-Status der FDA erhalten.
Study published in Nature shows J&J’s investigational SARS-CoV-2 vaccine elicits a strong immune response that protects against subsequent infection First-in-human Phase 1/2a clinical trial now underway in United States and Belgium; Phase 3 clinical trial expected to commence in September
The Diamond Princess cruise ship was put under quarantine offshore Yokohama, Japan, after a passenger who disembarked in Hong Kong was confirmed as a coronavirus disease 2019 case. We performed whole-genome sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) directly from PCR+ clinical specimens and conducted a phylogenetic analysis of the outbreak. All tested isolates exhibited a transversion at G11083T, suggesting that SARS-CoV-2 dissemination on the Diamond Princess originated from a single introduction event before the quarantine started. Although further spreading might have been prevented by quarantine, some progeny clusters could be linked to transmission through mass-gathering events in the recreational areas and direct transmission among passengers who shared cabins during the quarantine. This study demonstrates the usefulness of haplotype network/phylogeny analysis in identifying potential infection routes.
Due to the SARS-CoV2 pandemic, medical face masks are widely recommended for a large number of individuals and long durations. The effect of wearing a surg
Der Mund-Nasen-Schutz ist eine wirksame Barriere für Viren – aber das Tragen einer solchen Maske hat auch Nachteile: Die Atmung wird dadurch etwa messbar beeinträchtigt, wie eine Untersuchung des Universitätsklinikums Leipzig nachweist.
