Exosome-mediated mRNA delivery generates broad immune response to multiple SARS-CoV-2 proteins

Recently, researchers from The Johns Hopkins University School of Medicine, Baltimore, MD, USA, and Capricor Therapeutics, Inc., Beverly Hills, CA, USA, described a new approach to SARS-CoV-2 vaccine development using exosomes to deliver mRNAs that encode the antigens from multiple structural proteins of the virus.

Using wastewater epidemiology to monitor SARS-CoV-2 in Houston

Now, a team of researchers at Rice University, Baylor College of Medicine, and the Houston Health Department show SARS-CoV-2 RNA wastewater levels to be a strong predictive of trends in the nasal positivity rate two weeks in advance. This could help track the positivity rate for populations, speeding up the isolation and treatment of infected people.

Wake Forest Baptist scientists use pre-clinical model to develop a safe, effective flu vaccine for infants

Newborns and young infants are particularly susceptible to the flu and are six times more likely to die from the infection than older children. Currently there is no flu vaccine available for babies less than 6 months old.

Study suggests herd immunity to COVID-19 in New York City is low

Researchers in the United States have estimated that the proportion of people in New York City who developed antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first wave of the coronavirus disease 2019 (COVID-19) pandemic is around one in eight.

Promising yeast-expressed SARS-CoV-2 vaccine candidate effective in mice

Researchers at the Texas Children's Hospital Center for Vaccine Development, USA, have published a report on the preprint server bioRxiv that describes a yeast-expressed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) protein, a key target of current vaccine development efforts.

ACE2 and TMPRSS2 not the only virus-receptors to mediate SARS-CoV-2 entry

However, a recent study published on the preprint server bioRxiv in November 2020 uncovers the major role played by the N-terminal domain of the SARS-CoV-2 virus in host infection. This could be of great use in measuring the usefulness of antibodies used in convalescent plasma therapy for COVID-19.

Immune-evading variants can emerge in SARS-CoV-2, researchers warn

An international team of researchers has shown that a mutation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) – enables the pathogen to evade antibody-mediated immunity while maintaining replication fitness and increasing viral loads.

‘A great day for science and humanity’; Pfizer’s COVID-19 vaccine is found to be 90% effective

Pfizer and BioNTech have today announced their new vaccine candidate (BNT162b2) is 90% effective against SARS-CoV-2.

Researchers compare rhesus and cynomolgus macaques for SARS-CoV-2 vaccine trials

A team of researchers at the Biomedical Primate Research Centre based in the Netherlands have aimed to determine the effects of the SARS-CoV-2 pathogen on these monkeys and, subsequently, whether they make good animal models for future research in the area.

Study suggests honey and Nigella sativa expedites viral clearance in COVID-19 patients

A team of researchers from various institutes across Pakistan, Chile, Canada, and the USA recently conducted a clinical trial to investigate the potential effectiveness of a combination of honey and Nigella sativa (HNS) in treating COVID-19 patients. Their study is published on the preprint server medRxiv prior to the scientific peer review process.

Innate immunity key to limiting viral load in COVID-19 cases

As the coronavirus disease 2019 (COVID-19) pandemic continues to cause many difficulties for public health authorities, research is ongoing to understand how the virus can cause fatal effects on those infected and thereby suggest effective preventive and therapeutic measures against it.

People of color with rheumatic disease have worse COVID-19 outcomes

New research at ACR Convergence, the American College of Rheumatology's annual meeting, reveals that people of color with rheumatic disease have worse health outcomes from COVID-19 infection, are more likely to be hospitalized to treat their coronavirus infection, and are more likely to require invasive ventilator treatment

Study: Genetically edited form of herpes simplex virus outperforms leading vaccine candidate

A genetically edited form of a herpes simplex virus -- rewired to keep it from taking refuge in the nervous system and eluding an immune response -- has outperformed a leading vaccine candidate in a new study from the University of Cincinnati, Northwestern University and the University of Nebraska-Lincoln.
