Limited SARS-CoV-2 spread in childcare centers, finds study

A new study adds to the sum of evidence that children do not play a key role in the transmission of the SARS-CoV-2, the pathogen behind the current pandemic of COVID-19.

Can an immunosuppressive cancer drug promote SARS-CoV-2 entry into host cells?

A new study shows that rapamycin, an immunosuppressive drug used in some cancers, and its analogs, may have an undesirable effect on viral entry into the host cells. This finding could inform their use to treat symptomatic COVID-19.

Humoral immunity developed by DNA vaccine INO-4800 is effective against SARS-CoV-2 variants

A team of international scientists recently demonstrated that antibodies generated in response to the DNA vaccine INO-4800 can effectively neutralize some of the recently emerged variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), such as G614, 501Y.V1, and 501Y.V2.

Study examines SARS-CoV-2 seropositivity in healthy young adults and risk of reinfection

New research has been published in The Lancet Respiratory Medicine, which focuses on evaluating the effect of SARS-CoV-2 seropositivity on the possibility of developing SARS-CoV-2 infection in a young and healthy population. This study is based on the longitudinal prospective cohort study that involves the COVID-19 Health Action Response for Marines (CHARM).

Can fingerprick blood tests help evaluate antibody response and longevity against SARS-CoV-2 post-vaccination?

To monitor antibody level duration of vaccine-induced immune responses, a team of researchers in the U.S. – at Diacarta, University of California and VA Healthcare System, and the Franciscan University of Steubenville – evaluated the feasibility of using a single drop of fingerstick blood collected with flocked swabs for quantitative antibody response evaluation after COVID-19 vaccination.

Could virosome-based nanovaccines be a promising new approach to preventing viral diseases?

A recent review in the International Journal of Biological Macromolecules provides a novel overview of 'virosome'-based nanovaccine production, its properties, and its application in viral diseases, emphasizing its importance in SARS-CoV-2 vaccine discovery.

Public restrooms could serve as hotbeds for COVID-19 transmission

Flushing a toilet can generate large quantities of microbe-containing aerosols depending on the design, water pressure or flushing power of the toilet. A variety of pathogens are usually found in stagnant water as well as in urine, feces and vomit.

New mathematical model could help design new probiotics and tailored diets to prevent diseases

A new mathematical model for the interaction of bacteria in the gut could help design new probiotics and specially tailored diets to prevent diseases. The research, from Chalmers University of Technology in Sweden, was recently published in the journal PNAS.

Gut's immune response in COVID-19 patients may not provide adequate protection to other organs

Our guts may not provide long-lasting systemic immunity from COVID-19, which is where immune cells circulate through the body to provide protection to other organs, finds a new study published in Frontiers in Immunology.

Eviction bans authorized during COVID-19 pandemic reduced the infection rate, indicates study

A new study led by researchers at Johns Hopkins and the University of Pennsylvania uses computer modeling to suggest that eviction bans authorized during the COVID-19 pandemic reduced the infection rate and not only protected those who would have lost their housing but also entire communities from the spread of infections.

New machine-learning program accurately identifies COVID-19 conspiracy theories on social media

A new machine-learning program accurately identifies COVID-19-related conspiracy theories on social media and models how they evolved over time--a tool that could someday help public health officials combat misinformation online.

Despite global efforts, allocation and distribution of COVID-19 vaccines are not equitable

Ensuring COVID-19 vaccine access for refugee and displaced populations, and addressing health inequities, is vital for an effective pandemic response.

Use of ozone as a decontaminant for SARS-CoV-2

Researchers in Germany have demonstrated how an ozone-based decontamination device significantly reduces the volume of viral residue left on surfaces of two surrogate viruses for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Screening drug candidates for COVID-19 treatment using computational methods

Researchers identified two potential drug candidates that can inhibit SARS-CoV-2 in vitro. Their combination can work synergistically and increase their inhibitory effect.

New infectious hospital framework employs robotic tools for pandemic mitigation

In December 2019, a new viral infection was detected in Wuhan, China. On January 30, 2020, the World Health Organization declared the outbreak a public health emergency of international concern, and on March 11, the COVID-19 pandemic.

Sinovac COVID-19 vaccine shows 50% effectiveness in a cohort of Brazilian healthcare workers

CoronaVac is a well-tolerated vaccine containing inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and it induced humoral responses in phase 1 and 2 studies. Analysis of a Brazilian phase 3 clinical trial that evaluated 12,607 participants showed that the vaccine had an efficacy of 50.39% 15 days after the 2nd dose.

Study identifies COVID-19 vaccine inequity in Massachusetts

A new study led by Bisola O. Ojikutu of Brigham and Women’s Hospital in Boston suggests not only do these communities have a higher infection, but they are also experiencing lower vaccine distribution. The team suggests that reformation for equitable vaccine delivery is necessary to eliminate the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

COVID-19 patients who are overweight or obese may develop a more severe infection

COVID-19 patients who are overweight or obese are more likely to develop a more severe infection than patients of healthy weight, and they require oxygen and invasive mechanical ventilation more often. There is no increased risk of death .

Just one mRNA vaccine dose sufficient for people with prior SARS-CoV-2 infection

A small study, previously posted to the medRiv preprint server in early March, was recently published in the journal Science Immunology. The now peer-reviewed research led by E. John Wherry of the University of Pennsylvania Perelman School of Medicine finds people previously exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produced a more robust immune response after receiving the first — but not the second mRNA vaccine.

Chemical biomarker could be used to better manage treatments for COVID-19

Varying severity of COVID-19 symptoms in patients is reflected by levels of a chemical biomarker in their body which scientists say could be used to better manage treatments and other interventions, including vaccinations.
