COVID-19 mRNA vaccines safe and effective for pregnant and breastfeeding women

The current coronavirus disease 2019 (COVID-19) pandemic has brought untold devastation in its wake, with its rapid and asymptomatic spread to hundreds of millions of people the world over. Vaccines have been hailed as the way out of this situation, and a dozen or so are being rolled out in many different countries.

Breastfeeding safe and beneficial in SARS-CoV-2 infection

\With the onset of the coronavirus disease 2019 (COVID-19) pandemic, hundreds of millions of people became infected worldwide, including thousands of pregnant women near term. The question of vertical transmission to the infant via the placenta or breast milk was very real, leading to a near-total ban on breastfeeding in this group.

Nanotechnology and COVID-19 diagnosis and treatment

The development of nano-biosensors and nanoparticle-based vaccines and medicines has opened a new path toward better management of the coronavirus disease 2019 (COVID-19) pandemic. In a recently published article in the journal ACS Biomaterials Science & Engineering, scientists have reviewed recent advancements in nanotechnology-based diagnostic and therapeutic interventions against human coronaviruses.

Nanopore analysis identifies pseudouridine modifications in SARS-CoV-2

In a paper recently uploaded to the preprint server bioRxiv* by Fleming, Mathewson & Burrows (May 10th, 2021), nanopore devices are developed that allow identification of the passage of pseudouridine through a protein sensor. This further allowed the group to identify five conserved pseudouridine sites on the 3’ end of SARS-CoV-2 sub-genomic RNAs, which could potentially be beneficial to the virus in immune evasion.

Single dose of Oxford-AstraZeneca vaccine protective in previously infected recipients, suggests study

A recent report on the medRxiv* preprint server suggests that a single dose of the Oxford-AstraZeneca (ChAdOx1 nCoV-19) vaccine could elicit higher titers of neutralizing antibodies, effectively acting as a booster dose, in people who have already been infected by the SARS-CoV-2.

Phosphatidic acid is a key common substrate for hepatitis C and SARS-CoV-2 replication

A new study, released as a preprint on the bioRxiv* server, focuses on the lipid molecule called phosphatidic acid (PA), showing its crucial role in the replication of this virus, and thus its potential as a target for therapeutic intervention.

Designer SARS-CoV-2 RBD vaccine produces dramatically improved antibody response in preclinical trials

The importance of computational modeling in the prediction of the course of the ongoing COVID-19 pandemic, as well as evaluating multiple potential drug leads, has never been more clear. Now, a new study describes a set of designer vaccine antigens that may improve vaccine stability as well as enhance the neutralizing antibody response.

Research suggests Pfizer-BioNTech COVID-19 vaccine reprograms innate immune responses

Researchers in The Netherlands have warned that Pfizer-BioNTech’s coronavirus disease 2019 (COVID-19) vaccine induces complex reprogramming of innate immune responses that should be considered in the development and use of mRNA-based vaccines.

Total COVID-19 deaths could be 7 million

A new analysis from the Institute for Health Metrics and Evaluation (IHME), which independently researches health at the University of Washington School of Medicine, shows that the total global toll due to coronavirus disease 2019 (COVID-19) could be more than twice the officially reported number of deaths, at almost 7 million.

Combo COVID-flu vaccine protects against current and emerging variants in animal model

Now, in new research posted to the bioRxiv preprint server, scientists at Novavax, Inc. present a vaccine including recombinant influenza hemagglutinin (HA) antigen along with recombinant SARS-CoV-2 spike protein, with saponin Matrix-M adjuvant. Both have passed independent safety tests in phase 1 trials.

Human organoids useful for modeling COVID-19 variants of concern, finds study

A new study published on the bioRxiv* preprint server found that using human organoids could help with better characterizing the phenotype of several viral variants, including B.1.1.7. Their findings show the ribonucleic acid (RNA) shedding of the SARS-CoV-2 variant correlated with viral fitness and infectiousness.

COVID-19 in pregnancy does not significantly increase respiratory illness in newborns, says study

A new study published in the journal JAMA offers reassuring evidence that infants born to mothers with coronavirus disease 2019 (COVID-19), or even asymptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have little increase in respiratory symptoms over babies born to uninfected mothers.

Could in vitro glycoengineering help produce better SARS-CoV-2 spike candidates for vaccine research?

A vexing problem in the development of vaccines has been the need to achieve the right glycosylation profile for the viral antigens. A new study, recently released as a preprint on the bioRxiv* server, shows how a sequential cell-free approach produced complex N-glycans from simpler types, in a one-pot reaction.

Could COVID-19 rapid antigen tests aid international border control measures?

A recent study has explored the use of rapid antigen testing for COVID-19 at borders to reduce community transmission, and concluded that it would be effective only at lower volumes of passenger traffic.

Is Hong Kong’s fourth wave of COVID-19 due to the Q57H SARS-CoV-2 variant?

A recent article in the Centers for Disease Control and Prevention (CDC)’s Emerging Infectious Diseases reveals that the last of these was probably due to the introduction of a new variant from Nepal. This novel variant had been circulating in the community for about a month before the last outbreak was reported.

Peptide nucleocapsid vaccine candidate elicits protective T cell immunity against SARS-CoV-2 in vivo

A new study describes a synthetic peptide used as a platform to generate protective adaptive cellular immunity to the virus in rhesus macaques, which are the gold standard for preclinical testing in humans.

Novel platform has potential to detect many disease-related biomarkers in just one test

Most conventional molecular diagnostics usually detect only a single disease-related biomarker. Great examples are the PCR tests currently used to diagnose COVID-19 by detecting a specific sequence from SARS-CoV-2.
