New tests may help reveal the transcriptome of SARS-CoV-2 and predict disease course

As the COVID-19 pandemic continues to infect people in their hundreds of thousands around the world, a new study describes a panel of novel tests for genomic (g) and subgenomic (sg) mRNAs generated by SARS-CoV-2. Most assays in use at present are either qualitative or semi-quantitative, and cannot evaluate the transcription molecules in detail.

MVA SARS-CoV-2 vaccine candidate shows strong immunogenicity in preclinical trials

A new study reports the preclinical testing of a recombinant MVA (rMVA) candidate vaccine against SARS-CoV-2, the agent that is causing the current COVID-19 pandemic.

Could intranasal SARS-CoV-2 vaccines be a practical alternative to intramuscular shots?

The unchecked advance of COVID-19 has made it a top public health priority to produce a vaccine capable of inducing a safe and powerful protective response against its causative pathogen: SARS-CoV-2. An encouraging new study shows the immunogenicity, safety, and protective efficacy, of a Newcastle disease virus (NDV)-based intranasal vector vaccine in animal studies.

Study identifies features of potent SARS-CoV-2 neutralizing antibodies

Researchers at Columbia University have provided important insights into features of viral binding and recognition within a class of potent neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

How has the UK-derived SARS-CoV-2 mutant strain spread internationally?

Researchers analyzed Facebook-based mobility data and found that travelers from UK may have spread the new SARS-CoV-2 strain that originated in the UK to at least 16 countries by the beginning of December 2020.

Researchers map genetic changes that may have facilitated SARS-CoV-2’s jump from bats to humans

Researchers from the University of Cambridge and the Pirbright Institute in the UK have identified key genetic changes in SARS-CoV-2 that may be responsible for the virus’s jump from bats to humans. The team also determined which animals contain cellular receptors that allow the virus to enter cells more effectively, zoning in on potential animals that acted as an intermediary host in facilitating SARS-CoV-2’s zoonosis.

New findings could help better understand the mechanisms underlying severe malaria

The levels of small molecules called microRNAs (miRNAs) circulating in blood could help identify early on children with life-threatening forms of malaria, according to a study led by the Barcelona Institute for Global Health, an institution supported by "la Caixa" Foundation, in collaboration with the Manhiça Health Research Center (CISM) in Mozambique.

New UK-derived SARS-CoV-2 variant does not affect neutralizing antibodies efficiency, study says

A team of scientists conducted structural analysis of a newly emerged UK variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They present evidence that suggests that while the new variant has increased infectivity it is not resistant to neutralizing antibodies.
