Should a COVID-19 vaccine be mandatory for children?

As the search for a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine continues, with some candidate vaccines nearing the completion Phase III clinical trials, a trio of experts weighs in with some sound reasoning as to whether any future vaccine should be considered mandatory for children. The viewpoint article is published in the journal JAMA Pediatrics in September 2020.

Study indicates factors that could have contributed to delayed detection of SARS-Cov-2 in the US, Europe

SARS-CoV-2 arrived in Washington State somewhere between late January and early February 2020, sparking rapid community transmission of the virus that went undetected for several weeks before this community spread became evident, prompting a change in testing criteria to emphasize individuals with no travel history.

Blood clots can be an early indication of COVID-19, shows study

A new paper by vascular surgeons at the University of Miami Miller School of Medicine, published in the Journal of Vascular Surgery, describes how thrombosis (blood clots in the circulatory system) was an early indication of infection in a COVID-19 patient.

Study compares clinical features of COVID-19 and seasonal influenza in children

As the fall approaches, pediatric hospitals will start seeing children with seasonal influenza A and B. At the same time, COVID-19 will be co-circulating in communities with the flu and other respiratory viruses, making it more difficult to identify and prevent the novel coronavirus.

Scientists find new way to capture "live" images of immune cells inside the lungs

University of Calgary scientists have discovered how to capture "live" images of immune cells inside the lungs.

A better understanding of SARS-CoV-2 in children

Researchers at Duke University School of Medicine in Durham, North Carolina, have conducted a study showing that Hispanic ethnicity is associated with an increased risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among children.

Single-dose adenovirus-vectored vaccine protects mice against SARS-CoV-2

The researchers selected the human adenovirus type 5 on which to base their vaccine because this replication-defective vector had already been used in their Ebola vaccine, with an excellent safety and immunogenicity profile in a phase 1 trial. The current study aimed to produce a vaccine that could offer mucosal vaccination and enhanced protection against this respiratory virus.

New technique enables real-time observation of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

People may have a pre-existing immune response to COVID-19 thanks to common colds

Now, a new study shows that some people have immune responses against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, thanks to how the body reacted the last time it caught a cold. This means that even if a person has not been exposed to the novel coronavirus, the body has a memory of it and can trigger an immune response to fight the infection.

Iota-carrageenan from red seaweed inhibits SARS-CoV-2 in laboratory conditions

In a recent bioRxiv paper, a research group from the Marinomed Biotech biopharmaceutical company in Austria showed that a sulfated polysaccharide iota-carrageenan has the propensity to inhibit cell entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by using an in vitro neutralization assay.

Face masks do not lead to false sense of security, shows study

Existing limited evidence suggests that wearing face coverings to protect against COVID-19 does not lead to a false sense of security and is unlikely to increase the risk of infection through wearers foregoing other behaviours such as good hand hygiene, say researchers from the University of Cambridge and King's College London.

Researcher receives Outstanding Investigator Award for groundbreaking microvascular and circulation research

Sarah Yuan, MD, PhD, professor and chair of the Department of Molecular Pharmacology and Physiology at the USF Health Morsani College of Medicine, has received a highly competitive National Heart, Lung, and Blood Institute (NHLBI) Outstanding Investigator Award to continue breaking new ground in microvascular and circulation research.

BATM introduces three new diagnostic kits for COVID-19 and other respiratory illness

BATM, a leading provider of real-time technologies for networking solutions and medical laboratory systems, announces the launch of three new diagnostic kits to significantly advance the diagnosis of COVID-19 and other respiratory illnesses.

Scientists identify compounds that block replication of COVID-19 virus

As the death toll from the COVID-19 pandemic mounts, scientists worldwide continue their push to develop effective treatments and a vaccine for the highly contagious respiratory virus.

Genes associated with SARS-CoV-2 human lung cell infection

Now, a new study published on the preprint server bioRxiv in June 2020 attempts to make sense of this data to identify viral genes that are explicitly expressed in the cells infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could help reveal new therapeutic targets.

Steroidal drugs subvert SARS-CoV-2 interaction with ACE2 receptors

A new study by Italian researchers and published online on the preprint server bioRxiv* in June 2020 reports the ability of several existing steroidal drugs to reduce the binding of the SARS-CoV-2 to the ACE2 receptor. This could help define newer strategies using viral entry blockers to reduce viral load.

COVID-19 mouse model could accelerate the search for treatments, vaccines

The global effort to quickly develop drugs and vaccines for COVID-19 has been hampered by limited numbers of laboratory mice that are susceptible to infection with SARS-CoV-2, the virus that causes COVID-19.

Universal preoperative screening of pediatric patients for COVID-19 improves safety

Universally screening pediatric patients for COVID-19 before they undergo surgical procedures has allowed hospitals to improve safety by identifying all patients who test positive for the virus, half of whom have no symptoms, according to new research led by Children's Hospital of Philadelphia

Study sheds new light on how respiratory virus breaks into cells to cause infection

New research from University of Alberta microbiologists has shed new light on how the respiratory syncytial virus (RSV)--one of the most common viral infections--breaks into our cells to cause infection.

High prenatal choline levels may mitigate negative effects of COVID-19 on newborns

Pregnant women who take extra choline supplements may mitigate the negative impact that viral respiratory infections, including COVID-19, can have on their babies, according to a new study from researchers in the Departments of Psychiatry and Obstetrics and Gynecology at the University of Colorado Anschutz Medical Campus.
