Latest Coronavirus Disease COVID 19 News and Research

Can limiting the priming dose of a SARS-CoV-2 vaccine improve immunity?

Researchers from Northwestern University and the University of Rochester in the U.S. addressed this question in their study. The researchers also explored whether the vaccines administered across the world could confer sterilizing immunity while preventing severe disease and death.

Is non-severe SARS-CoV-2 infection characterized by early T cell proliferation?

To date, little evidence has been documented regarding the immune responses after the onset of the symptoms or virus detection. Further, no cross-sectional studies have been conducted that define the time of infection. Thereby, no report is available that explains the relationship between the earliest immune responses to COVID-19 and temporal kinetics. New research deals with this research gap using blood transcriptomics, multiparameter flow cytometry, and T cell receptor (TCR) sequencing methods.

What Covid means for the athlete’s heart

For sports fans across the country, the resumption of the regular sports calendar has signaled another step toward post-pandemic normality. But for the athletes participating in professional, collegiate, high school or even recreational sports, significant unanswered questions remain about the aftereffects of a Covid infection.

Colleges and universities plan for normal-ish campus life in the fall

Dr. Sarah Van Orman treads carefully around the word "normal" when she describes what the fall 2021 term will look like at the University of Southern California in Los Angeles and other colleges nationwide.

Study suggests T-cells don't determine survival in severe COVID-19

In the study, which appeared on the pre-print server medRxiv, the team found that when the monkeys were reinfected, the T cell-depleted animals showed anamnestic immune responses, the enhanced reaction of the body's immune system to an antigen that is related to an antigen previously encountered.

Research shows efficacy of early warning signals for disease emergence amid COVID-19

The study, published on the pre-print server medRxiv, shows that early warning signals (EWS) provide expected trends, predicting future epidemics and disease emergence.

CAL20.C SARS-CoV-2 variant skyrocketing in California evades host immune response

In a study published on the bioRxiv* preprint server, researchers report the effect of neutralizing antibodies from recovered patients or mRNA vaccinated individuals on neutralizing this variant.

Researchers take key step toward new drugs and vaccines to combat COVID-19

Researchers in the Oregon State University College of Science have taken a key step toward new drugs and vaccines for combating COVID-19 with a deep dive into one protein's interactions with SARS-CoV-2 genetic material.

Novel hydrogel-based vaccine formulation shows high efficacy against SARS-CoV-2

A fascinating new preprint research paper posted to the bioRxiv* server discusses impressively high neutralizing responses elicited with a single dose of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine formulation, which could help turn the tide of the current pandemic if validated.

Research explores sex differences in placental defenses against SARS-CoV-2 infection

A plethora of earlier studies has reported on the differences between the sexes in susceptibility to the currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as its severity. A new preprint research paper posted to the bioRxiv* server extends this to the placenta in pregnancy.

South Africa SARS-CoV-2 variant B.1.351 easily escapes Sputnik vaccine

A new preprint research paper posted to the medRxiv* server reports on vaccine resistance data that pushes the end of the pandemic further away.

Researchers to test a promising treatment for high-risk COVID-19 outpatients

The nation has been coping with the pandemic for more than a year, and in this time, researchers have learned a great deal about how to treat COVID-19.

New nanoparticle SARS-CoV-2 vaccine confers robust protection with single dose after two weeks

In a methodologically ‘state-of-the-art’ approach, US researchers have developed a protein-based nanoparticle vaccine against coronavirus disease (COVID-19), with a swift generation of antibodies and the potential to protect individuals who cannot receive other COVID-19 vaccines for medical reasons. The research is posted to the bioRxiv* preprint server.

Vermont to give minority residents vaccine priority

States have tried with limited success to get covid vaccines to people of color, who have been disproportionately killed and hospitalized by the virus.

Survey: Public trust in the CDC has declined during COVID-19 pandemic

Public trust in the federal Centers for Disease Control and Prevention has fallen during the coronavirus pandemic, with the decline bringing overall population-level trust in the agency to the same lower level of trust long held by Black Americans about the agency, according to a new RAND Corporation study.

Phase 1 clinical study of unique vaccine to protect against COVID-19 begins

A unique vaccine to protect against COVID-19 begins clinical testing Tuesday, 6 April, at the Walter Reed Army Institute of Research (WRAIR), part of the U.S. Army Medical Research and Development Command.

5 Apr 2021

Can universal vaccines and treatments against future SARS-CoV-2 variants be developed?

A team of researchers from Saudi Arabia and Spain recently quantified the rapid evolution of SARS-CoV-2 by tracking the mutations of the virus globally, focusing on the receptor-binding domain (RBD) of the virus’s spike protein, which determines its infectivity.

Researchers Identify potent small molecule inhibitors against SARS-CoV-2

A team of scientists from the USA and Sweden has recently screened 8 million small molecule inhibitors against SARS-CoV-2.

SARS-CoV-2 cryptic transmission modeling shows emergence of first wave in US and Europe

To analyze this cryptic transmission phase and the first wave of the pandemic that ensued, researchers from Italy, UK, and the US used a data-driven, spatial, stochastic, and age-structured epidemic model. They developed a mechanistic understanding of the evolution of the epidemic and estimated the time required for local transmission in various states and countries. The model developed by the team offers a statistical idea of SARS-CoV-2 introductions across European countries and many states in the US.
