Wed, 11/23/2022 - 06:11
Researchers explored the alterations in population immunity against SARS-CoV-2 Omicron variant infection and severe disease.

The safety and immunogenicity of a fourth dose of NVX-CoV2373

Wed, 11/23/2022 - 05:46
Researchers assessed the immunogenicity and safety of a fourth homologous boost dose of a recombinant SARS-CoV-2 spike protein vaccine called NVX-CoV2373.

Study shows clear shifts in SARS-CoV-2 mutational spectrum during evolution

Wed, 11/23/2022 - 05:44
Researchers examined whether the mutational process of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) itself has changed during the evolution of SARS-CoV-2.

Vaginal birth after previous cesarean section linked with higher risk of pelvic floor surgery

Wed, 11/23/2022 - 05:18
Vaginal birth after a previous cesarean section is associated with an increased risk of pelvic floor surgery compared with planning another cesarean, according to research publishing November 22nd in the open access journal PLOS Medicine.

The binding and functional serologic responses to COVID-19 vaccination in children with history of MIS-C

Wed, 11/23/2022 - 05:17
Researchers evaluated the serological responses elicited by COVID-19 vaccinations in children who developed MIS-C following a previous SARS-CoV-2 infection.

New York sewer rats are easily infected by SARS-CoV-2, according to new study

Wed, 11/23/2022 - 04:50
Researchers evaluated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure among rats inhabiting New York City (NYC) during the fall of 2021.

Study shows no undetected monkeypox virus transmission before May 2022 in Rotterdam and Amsterdam

Wed, 11/23/2022 - 03:16
Researchers investigated whether undetected human monkeypox virus transmission occurred before Rotterdam and Amsterdam's first documented monkeypox cases.

Fungi detected in 35 cancer types, often intracellular

Tue, 11/22/2022 - 23:34
In a recent article published in the journal Cell, researchers found fungal deoxyribonucleic acid (DNA) and cells at low abundances across many human cancers, with cancer type-dependent variations in fungus community composition and fungal-bacteriome interactions.

Myocarditis after COVID vaccination is rare but higher in younger males

Tue, 11/22/2022 - 23:08
In a recent study published in the Canadian Medical Association Journal, researchers observed the incidence of myocarditis following messenger ribonucleic acid (mRNA)-based vaccination against coronavirus disease 2019 (COVID-19). Additionally, they compared their estimates with expected rates based on the historical rates assessed before the COVID-19 vaccination rollout in British Columbia (BC), Canada.
