Reducing COVID-19 burden with monoclonal antibodies and vaccination

Researchers in the United States, the UK and France have shown that using antiviral monoclonal antibodies in combination with vaccination can be expected to suppress the transmission of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) and reduce the burden of coronavirus disease 2019 (COVID-19) more than vaccination alone.

Will SARS-CoV-2 eventually become just another seasonal coronavirus?

Could SARS-CoV-2 become just a seasonal nuisance in the next decade, causing just coughs and sniffles like a common cold, suggests new research? Scientists at the University of Utah, USA, tried to predict the possible future of the novel coronavirus using mathematical models that use learnings from the current pandemic on changes in human immunity over time.

Intensity and duration of SARS-CoV-2 immunity may depend on ABO blood group

A team of scientists from Canada and Spain recently evaluated the durability of antigen-specific immune responses in COVID-19 recovered individuals. They have also identified potential host factors associated with robust and long-lasting anti-SARS-CoV-2 immunity.

Tissue-resident memory T cells found in lungs of people who had COVID-19 10 months ago

In recent research by Judith Grau-Expósito et al., scientists identify circulating virus-specific T cell responses during acute SARS-CoV-2 infection with functional, migratory, and apoptotic patterns modulated by viral proteins and associated with clinical outcome.

An exploratory study of T-cell and antibody responses after COVID-19 mRNA vaccination

Recent COVID-19 investigations have found that up to half of immunocompromised individuals struggle to produce antibodies after receiving their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations.

Immunologists decode T cell responses that occur during COVID-19 infection

An international team of researchers from the Institute for Research in Biomedicine, affiliated to the Università della Svizzera italiana, has deciphered, at single cell resolution, the T cell responses occurring during COVID-19 infection.

Moderna's COVID vaccine proves effective against South African variant in primates

Researchers in the United States have demonstrated the efficacy of Moderna’s coronavirus disease 2019 (COVID-19) vaccine at protecting against the South African B.1.351 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in non-human primates.

NFCR announces winners of 2021 Salisbury Award Competition

The National Foundation for Cancer Research (NFCR) announced winners of the 2021 Salisbury Award Competition for Entrepreneurial Translational Research, selected from among eight semi-finalists after pitch presentations in front of a judging committee consisting of prominent cancer research scientists, clinicians, early-stage investors and business leaders.

Study attempts to standardize humoral immune Correlates of Protection (CoP) in COVID-19

A new study aims to identify antibody-based biomarkers associated with the humoral immune response that could be a standard CoP candidate for COVID-19. Further, standardization of research methods to measure these biomarkers has also been conducted.

Modeling the risk of SARS-CoV-2 outbreaks upon lifting non-pharmaceutical interventions (NPIs)

In a paper recently uploaded to the preprint server medRxiv* by Sachak-Patwa et al. (May 22nd, 2021), mathematical models are developed to assess the probability and impact of such localized outbreaks, accounting for changing general immunity levels in the population as vaccines are distributed.

Person infected with SARS-CoV-2 can transmit infection to three to five other people

What started as the preliminary analysis of routine laboratory data has since evolved into the largest-ever study of viral load levels in patients with SARS-CoV-2.

Next-generation SARS-CoV-2 subunit vaccine candidate elicits powerful immunity in preclinical trials

New research – by scientists at the University of Chicago, Johns Hopkins School of Medicine and the University of Iowa in the USA – describes a novel COVID-19 vaccine candidate that has achieved impressive immunologic results in mouse studies.

SARS-CoV-2 UK variant may induce more inflammation, study suggests

Since COVID-19 was first detected in December 2019 in Wuhan, China, many different variants of its causative virus – SARS-CoV-2 – have emerged. Through increased viral fitness, some of these have risen to predominance over earlier variants in a remarkably short period of time. New research, by a team of scientists at major institutions in France, examines the reasons behind this phenomenon in one such variant of concern (VOC), the so-called UK variant.

Do vaccinations result in anti-SARS-CoV-2 antibodies in human milk?

The aim of this study investigates the impact of different types of vaccines on the anti-SARS-CoV-2 Immunoglobulin A (IgA) and Immunoglobulin G (IgG) antibody levels found in human milk.

Healthcare workers were three times more likely to get infected by COVID-19, shows study

A study of healthcare workers shows they were three times more likely to become infected during the COVID-19 pandemic compared to the general population. Around one in five of workers who were infected were asymptomatic and unaware they had COVID-19.

Do mixed COVID-19 vaccines provide immunity?

The initial results of the CombivacS trial found that the antibody levels in individuals increased by 150 times when the Pfizer messenger ribonucleic acid (mRNA) vaccine was given after a first dose of the AstraZeneca severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine, with only mild common side effects.

Novel natural compounds may help treat COVID-19, study suggests

A new study in the journal Chemistry Europe reports two natural compounds identified by virtual screening and computational modeling as having great promise for the development of drugs against SARS-CoV-2.

Mild cases of COVID-19 provide lasting antibody protection, shows study

Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all the while.

Could saffron be an effective supplement for helping manage COVID-19?

A new study, published in the journal Cell Press, explores the potential use of saffron (Crocus sativus L.) as a drug supplement for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19).
