Frequent testing increases chance of detecting COVID-19 infections

The chance of detecting the virus that causes COVID-19 increases with more frequent testing, no matter the type of test, a new study found. Both polymerase chain reaction and antigen tests, paired with rapid results reporting, can achieve 98% sensitivity if deployed at least every three days.

Antibody development against SARS-CoV-2 following Moderna vaccine

In a paper recently uploaded to the preprint server medRxiv* by Belda et al. (June 27th, 2021) two seroconversion panels containing the sera of individuals that received the Moderna (mRNA-1273) vaccine are compared, and the impact on neutralizing IgG antibody titers in these individuals is analyzed.

Moderna's COVID vaccine effective against emerging variants including Delta

Researchers in the United States have analyzed the neutralizing activity of Moderna’s mRNA-1273 vaccine against several variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Study shows effects of COVID-19 pandemic on the health of women aged 50 to 70 years

In a study involving 34 women aged 50-70, researchers at the University of São Paulo (USP) in Brazil performed objective measurements of the impact on the subjects' health of the decrease in physical activity observed during the period of social distancing and isolation imposed by COVID-19.

Solar irradiation inactivates SARS-CoV-2 and other human coronaviruses, finds study

Coronaviruses irradiated with simulated sunlight used to infect cells showed reduced infectivity and reduced viral replication compared to viruses that were not irradiated.

Intranasal COVID-19 vaccine developed from bacterial extracellular vesicle induces robust antibody response in preclinical trials

A team of US-based scientists recently developed a novel vaccine candidate against SARS-CoV-2, the causative pathogen of COVID-19. The vaccine is composed of extracellular vesicles of Salmonella typhimurium incorporated with the spike receptor-binding domain (RBD) of SARS-CoV-2. Upon intranasal administration in hamsters, the vaccine induces strong blood antibody titers and protects against severe COVID-19.

Is the SARS-CoV-2 delta variant threatening vaccine efficacy?

A new study in the UK, by researchers at Imperial College London, The Francis Crick Institute and the University of Glasgow, explores the loss of coronavirus disease 2019 (COVID-19) vaccine efficacy against the virus behind the current pandemic caused by the emergence of newer variants that have undergone mutational escape.

Effectively monitoring COVID-19 in reopened educational institutions: the San Diego model

An interesting new study from the University of California San Diego (UCSD) shows that using preventive measures to block viral transmission, coupled with repeated testing and rapid turnaround times for the results, can successfully prevent outbreaks associated with the reopening of educational institutions.

Is mild COVID-19 in children due to stronger antiviral innate immunity in the upper airway?

A new preprint on the medRxiv* server adds fuel to this train of thought, showing that the required cell program is already active in children – namely, a higher expression of specific pattern recognition receptors (PRRs), which mediate an interferon (IFN) response.

Assessing the safety of inactivated SARS-CoV-2 vaccine (CoronaVac) in healthy children and adolescents

New clinical trial data, recently published in The Lancet’s Infectious Diseases, presents an initial report on the effect of an inactivated SARS-CoV-2 vaccine, CoronaVac, on children and adolescents from ages 3-17 in a double-blind, randomized setting.

Researchers launch a new smell training device for rehabilitation after Covid-19

Smell training used to be mainly a thing for wine enthusiasts, gourmets, and perfumers. But Covid-19 changed all that, and now Malmö University researchers have launched a new smell training device.

SARS-CoV-2 inhibited by pyrimidine biosynthesis inhibitors in conjunction with nucleoside analogs

In an effort to hasten the research on identifying antiviral drugs for SARS-CoV-2 infection, researchers from the U.S. and Switzerland performed extensive drug screening for antiviral activity using live virus infection in human respiratory cells. As a result, they identified a set of possible drug candidates that could potentially be tested in clinical trials.

COVID-19 prevalence among hospitalized infants may depend on levels of community transmission

How common COVID-19 is among infants may depend on the degree of the pandemic virus circulating in a community, a new study finds.

Study shows SARS-CoV-2 breakthrough infections fewer among fully vaccinated

A team of researchers at Indiana University reports genomic evidence of breakthrough infections in fully vaccinated individuals. The study, posted to the pre-print server medRxiv*, suggests that fully vaccinated individuals, including those with asymptomatic infections, are less likely to serve as a source of infection for others.
