Disparities in COVID-19 burden among high-risk communities

New study findings demonstrate that non-Whites, lower-income individuals, and individuals with lower education levels have the highest SARS-CoV-2 seroprevalence and lowest vaccination seroprevalence.

Never mind toys, it’s time to ask Santa for crutches and catheters

America's hospitals, strained by nearly two years of fighting the covid-19 pandemic, are now scrounging for basic medical supplies.

Health experts worry CDC’s covid vaccination rates appear inflated

For nearly a month, the Centers for Disease Control and Prevention's online vaccine tracker has shown that virtually everyone 65 and older in the United States — 99.9% — has received at least one covid vaccine dose.

Kinetics and persistence of SARS-CoV-2 antibody responses

New study findings indicate that antibody detection shows a distinct pattern depending on the type of antibody detected, the target antigen, the test design, antibody avidity level, and COVID-19 severity.

Effect of SARS-CoV-2 variant emergence on efficacy of neutralizing antibodies and vaccines

A review article focuses on the efficacy of neutralizing antibodies and vaccines against the SARS-CoV-2 variants.

Immune responses against SARS-CoV-2 Delta variant after BNT162b2 vaccination in people living with HIV

Researchers from Sorbonne Universite have been investigating the effect of the BNT162b2 mRNA vaccine on HIV-positive individuals.

Increased risk of COVID-19 breakthrough infections in fully vaccinated people with HIV

New study results showed a 41% greater incidence of breakthrough infections in people with HIV compared to that of people without HIV.

Glycans strengthen and lengthen SARS-Cov-2 spike binding to ACE2

New study results provide evidence that the binding between SARS-CoV-2 RBD and host ACE2 receptor is aided by the glycosylation on each protein.

Youths did not seek healthcare both before and during the COVID-19 pandemic

New study results show that although healthcare access patterns among youth were similar before and during the pandemic, COVID-19 has added some new barriers to seeking medical care when needed.

Potential association between senescence and aging in COVID-19

A review published in Cells discussed characteristics of cellular senescence and its potential role in COVID-19.

Immunogenicity and safety of COVID-19 subunit vaccine Nanocovax in animal models

Researchers have developed Nanocovax, a COVID-19 subunit vaccine based on recombinant protein technology to produce the extracellular (soluble) portion of the S protein of SARS-CoV-2.

Positive results from Phase 3 study of Medicago’s plant-based COVID-19 vaccine candidate announced

Medicago, a biopharmaceutical company headquartered in Quebec City, and GlaxoSmithKline today announce positive efficacy and safety results from the global Phase 3 placebo-controlled efficacy study of Medicago’s plant-based COVID-19 vaccine candidate in combination with GSK’s pandemic adjuvant, conducted in over 24,000 subjects, adults 18 years and above, across six countries.

Sugar-binding pockets in N-terminal domain may increase SARS-CoV-2 infectivity

The N-terminal domain has a fold that can bind sugar, and new research led by Jonathan Lees from Oxford Brookes University found the sugar-binding pockets near the N-terminal domain help to increase viral infectivity. Furthermore, the findings show that the SARS-CoV-2 sugar-binding pockets are evolving with added loops observed in the pockets of new variants.

Mass-spectrometry and PCR testing identifies various targets related to SARS-CoV-2 VOCs

New research posted to the medRxiv* preprint server suggests that the Agena MassARRAY SARS-CoV-2 Panel PCR test effectively detects a variety of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants.

9 Dec 2021

SARS-CoV-2 variants are evolving new ways to evade antibodies and vaccines

Continued replication of severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2) under selective pressure from natural and vaccine-induced immunity has led to the emergence of variants of concern (VOCs) with increased transmissibility or virulence.

For most young people, COVID vaccine-related myocarditis is not serious

A new study published in the journal Circulation aimed to describe a large case series of suspected myocarditis temporally related with the COVID-19 vaccine in adolescents and young adults below 21 years of age across the United States and Canada.

Neutralization antibodies elevated in nursing home residents after COVID-19 mRNA boosters

Researchers from the United States, in their recent study published on the preprint server medRxiv*, have evaluated the humoral responses to third vaccine dose in nursing home residents and healthcare workers (HCW) and found that that second booster (or third vaccine dose) significantly increased anti-spike, anti-receptor binding domain (RBD), and neutralization titers in almost all nursing home residents and HCW to considerably higher levels than what was attained after the completion of the initial two-dose vaccine series.

Routine immunization coverage declined in first year of COVID

A new study published on the medRxiv* preprint server investigated changes in RI coverage using two key indicators – diphtheria-tetanus-pertussis first-dose (DTP1) and third-dose (DTP3). DTP3 serves as a general marker for immunization system performance, while DTP1 is used as a proxy for inequity - quantifying Zero Dose (ZD) children––those that receive no childhood vaccinations

Researchers identify a molecular culprit for COVID-19's seasonal nature

Not to pile on, but winter is coming and the COVID-19 pandemic is about to get worse. Not necessarily because of omicron – scientists are still working that one out – but because there’s more evidence than ever that COVID-19 is a seasonal disease.
