Estimation of the SARS-CoV-2 infectious period

A new study focused on estimating the temporal dynamics of transmissibility of infected cases in the absence of intervention measures (unmitigated generation interval).

Relaxation of COVID-19 restrictions led to the reemergence of seasonal respiratory viruses in Houston

A Houston Methodist study showed a rapid return of seasonal respiratory viruses after COVID-19 restrictions were relaxed in Texas, demonstrating the effectiveness of masking, distancing and other precautionary measures at stopping the spread of many respiratory illnesses, not just COVID-19.

Limited immune responses three months after Pfizer-BioNTech vaccination among elderly

In this study, published on the medRxiv* preprint server, the humoral response to SARS-CoV-2 was assessed before and after three months of administration of the BNT162b2 mRNA COVID-19 vaccination (Pfizer-BioNTech). In addition, elders' humoral responses were compared to those of a younger group, and a functional neutralization experiment against the Wuhan-Hu-1 (WH1) virus and the Delta variant was carried out.

Vaccine-induced immune responses for SARS-CoV-2 in patients receiving anti-CD20 B-cell depleting therapies

A new study published on the medRxiv* preprint server analyzed the trajectories of anti-SARS-CoV-2 antibodies in patients from the RituxiVac study were compared to healthy volunteers. In addition, they investigated the immunogenicity of a third vaccine dose in previously non-responding patients.

CDC study finds Pfizer-BioNTech COVID vaccine provides high protection against hospitalization in adolescents

New research from the Centers for Disease Control & Prevention (CDC) suggest vaccines are highly protective against severe acute respiratory coronavirus 2 (SARS-CoV-2). Two doses of the Pfizer-BioNTech vaccine showed a 93% effectiveness against hospitalization. The findings add to a previous clinical trial that found vaccinated adolescents with 100% protection against SARS-CoV-2 infections.

Higher antibody level correlates with greater vaccine protection against COVID-19

By measuring antibodies against the SARS-CoV-2 spike protein in participants in a phase 3 trial of the Moderna COVID-19 vaccine, researchers found that the higher the antibody level, the greater the vaccine protection against COVID-19.

Discovery of a broad-spectrum antiviral activity in self-assembling immunostimulatory duplex RNAs

A new study, published on the bioRxiv* preprint server, has discovered a class of new immunostimulatory RNAs while studying influenza infection-associated host genes in human lung epithelial cells using small interfering RNAs (siRNAs). Scientists revealed that these short duplex RNAs could induce type I and type III interferons (IFN-I/III) in a wide variety of cells.

A novel reverse epitope discovery approach to characterize SARS-CoV-2 public CD4+ αβ T cell clonotypes

A new study, published on the bioRxiv* preprint server, has focused on public clonotypes, i.e., clones found in multiple individuals, for the development of a novel reverse epitope discovery technique. This technique holds greater potential for population-wide applications.

Mouthwash containing an antiviral phthalocyanine derivative shortens hospitalizations due to COVID-19

In a study published in the journal Scientific Reports, a research group from Brazil showed how antiviral anionic phthalocyanine derivative used in a mouthwash protocol may not only reduce the symptoms of coronavirus disease (COVID-19), but also hamper the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Oral Hsp90 inhibitor SNX-5422 interferes with replication machinery of SARS-CoV-2

A new study evaluates the efficacy of SNX-5422 as a post-exposure prophylactic treatment.

23 Nov 2021

Study shows risk of MIS-C post mRNA vaccination against COVID-19 in children with autoimmune complications

Researchers discuss two cases of MIS-V after the patients had received the SARS-CoV-2 vaccine from Pfizer/BioNTech (BNT162b2).

23 Nov 2021

Strong antibody responses against harmless coronaviruses may protect against SARS-CoV-2

Infections with the novel coronavirus and vaccination lead to strong antibody responses against SARS-CoV-2. Immune responses to other human coronaviruses, which mostly only cause harmless colds, also provide some protection against SARS-CoV-2.

23 Nov 2021

SARS-CoV-2 moves between permissive cells and non-permissive neuronal cells via tunneling nanotubes (TNT)

Scientists investigate the neuroinvasive potential of SARS-CoV-2 and the role of tunneling nanotubes (TNTs) in spreading the infection to neighboring cells.

23 Nov 2021

Antigenic cocktail produced in Nicotiana benthamian plant as a potential COVID-19 vaccine candidate

Scientists utilize N. benthamiana for producing the N-protein and an antigenic cocktail containing the N-protein and SARS-CoV-2 S RBD.

23 Nov 2021

Tobacco mosaic virus nanoparticle-based novel COVID-19 vaccine candidate

Scientists generate a VLP type NP platform made of recombinant viral antigens conjugated with TMV virions.

23 Nov 2021

Inactivated virion-based vaccine confers robust cell-mediated immunity against major SARS-CoV-2 variants

Indian researchers determine the magnitude, quality, and persistence of cellular and humoral memory responses after vaccination with BBV152/Covaxin.

WHO’s C-TAP and MPP finalize licensing agreement with CSIC for COVID-19 serological antibody technology

WHO's COVID-19 Technology Access Pool and the Medicines Patent Pool today finalized a licensing agreement with the Spanish National Research Council for a COVID-19 serological antibody technology.

KHN’s ‘What the Health?’: The big Biden budget bill passes the House

President Joe Biden's "Build Back Better" social spending bill passed the House last week, but the legislation faces a new and different set of hurdles in the Senate, where it will need the support of every single Democrat, plus approval by the Senate parliamentarian.

23 Nov 2021

Systematic review finds COVID-19 vaccine efficacy remains high for at least six months

Scientists have conducted a systematic review of published studies investigating the duration of efficacy of COVID-19 vaccines against SARS-CoV-2 infection and disease severity.

23 Nov 2021

An increase in the half-life of remdesivir for COVID-19 treatment

In this study, researchers analyzed several drug candidates to investigate their efficacy against a broad spectrum of coronaviruses in cell culture studies.
