Pfizer-BioNTech mRNA vaccine reduces both symptomatic and asymptomatic COVID-19 infection in case study

Follow-up of vaccinated and unvaccinated individuals at St. Jude Children’s Research Hospital revealed asymptomatic infection reduced by 90% and symptomatic infections reduced by up to 96% in vaccinated people compared to those not vaccinated.

How did SARS-CoV-2 first evolve in humans?

In a perspective article recently published in the journal Science, Hyeryun Choe and Michael Farzan from the Scripps Research Institute, USA, have described the early-stage evolution of SARS-CoV-2 in humans. They have provided a detailed overview of how early mutations in SARS-CoV-2 spike protein facilitate its adaptation in human systems.

Immunosuppression in COVID-19 promotes emergence of multiple immune escape mutants

An interesting new study describes the emergence of several such variants from a chronically immunosuppressed COVID-19 patient, who remained infected for over 170 days before clearing the virus.

The ancestor of SARS-CoV-2’s Wuhan strain was circulating in late October 2019

The SARS-CoV-2 was first reported in a case from Wuhan, China, in December 2021, and subsequently became the cause of the COVID-19 pandemic that is ravaging the world today. A new study in the journal Molecular Biology and Evolution tracks its variants all over the world since the onset of the pandemic.

Are infants at greater risk of COVID-19 than children?

The widely circulating SARS-CoV-2 has caused the devastating COVID-19 pandemic. The impact of this infection varies significantly with age, sparing young children for the most part, though not completely. However, a new study, released as a preprint on the medRxiv* server, shows that infants are not as resistant to the virus as children are. The researchers trace this to the expression of ACE2 to varying extents in different groups.

Could antiviral surface designs help reduce SARS-CoV-2’s spread?

In an effort to improve surface decontamination methods, researchers from the Indian Institute of Technology (IIT), Bombay, looked at fabricating surfaces with virucidal properties. More specifically, these scientists investigated surface properties that could prevent the survival of viruses on these surfaces, particularly SARS-CoV-2.

Human organoids useful for modeling COVID-19 variants of concern, finds study

A new study published on the bioRxiv* preprint server found that using human organoids could help with better characterizing the phenotype of several viral variants, including B.1.1.7. Their findings show the ribonucleic acid (RNA) shedding of the SARS-CoV-2 variant correlated with viral fitness and infectiousness.

COVID-19 may impact the heart health of young, healthy adults

New research published in Experimental Physiology highlight the possible long term health impacts of COVID-19 on young, relatively healthy adults who were not hospitalized and who only had minor symptoms due to the virus.

Increased symptomatic levels of COVID-19 may be associated with psychiatric symptoms

A significant level of symptoms of depression, anxiety and post-traumatic stress may follow COVID-19 independent of any previous psychiatric diagnoses, according to new research by Columbia University Mailman School of Public Health with colleagues at Universidade Municipal de São Caetano do Sul in Brazil.

Highly efficient immune response in asymptomatic SARS-CoV-2 patients

Researchers in Singapore have investigated the role of SARS-CoV-2-specific antibodies and T-cells in asymptomatic individuals suffering from COVID-19. They found that, contrary to some initial hypotheses, asymptomatic individuals mount an adaptive immune response on par with symptomatic individuals, demonstrating that T cell response does not appear to be correlated with symptom severity.

SARS-CoV-2 infection prolongs viral shedding and lymphocyte loss in patients with cancer

Patients with cancer have a more challenging time with infections while undergoing treatment — placing them as high-risk for severe COVID-19 illness and death. However, how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interacts with cancer therapies remains poorly understood.

Global spread of COVID-19 has raised serious concern for patients with transthyretin amyloidosis

The global spread of COVID-19 has raised serious concern for patients with chronic disease. A correlation has been identified between the severity of COVID-19 and a patient's preexisting comorbidities.

Cryptic pocket on the surface of SARS-CoV-2 may be a promising treatment target

In a new study currently available on the bioRxiv* preprint server, a multinational group of researchers modeled an entire membrane-embedded spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and highlighted the potential of a specific mapping approach for unveiling cryptic, potentially druggable pockets on the viral surface.

Study may lead to personalized treatments for cystic fibrosis

Some 2,103 mutations have been identified in patients with cystic fibrosis (CF), the most common fatal genetic disease in Canada, and together they pose huge challenges for patients and researchers, including those affiliated with Université de Montreal and its teaching hospital, the Centre hospitalier de l'Université de Montréal (CHUM).

Study reports vitamin C inhibits SARS-CoV-2 virus main protease

Based on structural analysis, researchers found that vitamin C binds to 3CLpro, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease essential in viral replication. In vitro cell inhibition studies also showed vitamin C could inhibit 3CLpro, indicating a possible new antiviral treatment method.

Israeli study shows real-world efficacy of Pfizer-BioNTech’s COVID-19 vaccine

Researchers have conducted an analysis of nationwide surveillance data from Israel demonstrating the real-world effectiveness of Pfizer-BioNTech’s BNT162b2 vaccine at protecting against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Indian SARS-CoV-2 variant shows enhanced host cell entry and immune evasion

A study conducted by researchers in Germany has found that the B.1.617 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in India entered certain types of lung and intestine cells with slightly increased efficiency compared with the original wild-type strain.

Study investigates 12-month respiratory outcomes in patients hospitalized for COVID-19

A new study has shown that most patients discharged from hospital after experiencing severe COVID-19 infection appear to return to full health, although up to a third do still have evidence of effects upon the lungs one year on.

Study: Novavax Covid-19 vaccine is efficacious against the B.1.351 South African variant

The published data provide additional detail of an initial analysis conducted in January, while more robust data from a complete analysis of the study was subsequently shared in March 2021.
