Antibody-mediated protection against symptomatic COVID achieved at low serum neutralizing titers

In a recent study posted to the medRxiv* preprint server, researchers in the United States assessed the efficiency of protection mediated by antibodies against symptomatic coronavirus disease 2019 (COVID-19) at low serum-neutralizing titers.

24 Oct 2022

Analyses of 11 commercially available PCR kits to detect monkeypox virus DNA

In a recent study posted to the medRxiv* server, researchers in Germany and Switzerland evaluated 11 commercial reverse transcription-polymerase chain reaction (RT-PCR) kits (A to L) for Monkeypox virus (MPXV) detection.

Fully vaccinated U.S. frontline workers may experience reduced severity, duration, and viral shedding during SARS-CoV-2

Researchers investigated the association between two or three doses of the messenger ribonucleic acid (mRNA) COVID-19 vaccine and viral loads and symptoms during infections with different SARS-CoV-2 variants.

23 Oct 2022

Study indicates that the major determinants of SARS-CoV-2 pathogenicity reside outside of the spike protein

Researchers at Boston University made a chimeric recombinant SARS-CoV-2 encoding the spike glycoprotein gene of Omicron in the backbone of an ancestral SARS-CoV-2 isolate.
