Study suggests SARS-CoV-2 Omicron showed increased household transmission and immune evasion in Norway

In a recent study posted to the medRxiv* preprint server, a team of researchers from Norway used contact tracing data to measure and compare the household secondary attack rate (SAR) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron and Delta variants at a time of prominence or both variants in the country. … Read more

Clinical severity of COVID-19 caused by SARS-CoV-2 variants and the effectiveness of mRNA vaccines against them

A recent study posted to the medRxiv* preprint server examined the clinical severity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Alpha, Delta, and Omicron variants of concern (VOCs) and compared vaccine effectiveness against each VOC. Study: Clinical Severity and mRNA Vaccine Effectiveness for Omicron, Delta, and Alpha SARS-CoV-2 Variants in … Read more

Rapid generation and evaluation of an mRNA vaccine candidate specific to Omicron

A recent study posted to the bioRxiv* preprint server demonstrated the development of a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant-specific messenger ribonucleic acid (mRNA) vaccine candidate, called receptor-binding domain (RBD)-Omicron mRNA (RBD-O mRNA) vaccine and the evaluation of the same in mice models. Study: An mRNA vaccine candidate … Read more
