Pfizer COVID-19 vaccine elicits antibodies in blood and breastmilk simultaneously, finds study

A new study adds to the sum of knowledge around this issue, showing a highly synchronized and rapid development of an antibody response in breast milk and serum, which reached stable levels around two weeks after the second dose of the vaccine was administered.

Tiny antibodies naturally generated by llamas can be effective against COVID-19

As the fight against COVID-19 continues, scientists have turned to an unlikely source for a potentially effective treatment: tiny antibodies naturally generated by llamas.

Research demonstrates multivalent nanobodies overcome SARS-CoV-2 variant mutations

In a recent bioRxiv* preprint paper, researchers isolated anti-RBD nanobodies from llamas and “nanomice” (they engineered to produce VHHs cloned from alpacas, dromedaries and camels).

Analysis shows moderate evidence for SARS-CoV-2 recombination

Recently, a team of researchers from the US performed a comprehensive recombination analysis across all medically relevant human coronaviruses, including 158,118 public seasonal hCoV, SARS-CoV-1, SARS-CoV-2, and MERS-CoV genome sequences with the help of the RDP4 software. They aimed at identifying the current and future risks of the emergence of recombinants of SARS-CoV-2

2% of individuals carry 90% of SARS-CoV-2 virions: Study of 72,500 tests

In a new study published on the medRxiv* preprint server, researchers analyzed viral loads from pre-symptomatic and asymptomatic individuals in an extensive university surveillance program.

SARS-CoV-2 variants rapidly arise in non-human hosts, potential risk for human reinfection

The study, published on the preprint server bioRxiv*, highlights the need to study viral evolution and pathogenesis in human and animal hosts. This could help prevent future outbreaks that may mimic the magnitude of the current COVID-19 pandemic.

Scientists study seven human coronavirus envelope proteins using topology prediction and molecular modeling

A new study by researchers at the University of the Western Cape aimed to determine why some coronaviruses are more virulent than others. The team speculates that the increased flexibility of the PDZ-binding motif (PBM) of SARS-CoV, MERS-CoV, and SARS22 CoV-2 to be more flexible than the PBM of hCoVs 229E, NL63, OC43, and HKU1.

Vaccine mRNA not found in breast milk after COVID mRNA vaccination

A study conducted by researchers in the United States has found no evidence to suggest that the messenger RNA (mRNA) present in the Pfizer-BioNTech and Moderna vaccines that protect against coronavirus disease 2019 (COVID-19) can be transferred to human breast milk.

UK variant of SARS-CoV-2 could be more deadly than previous strains

Researchers have conducted a study showing that the B.1.1.7 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in the UK is associated with a significantly increased risk of death compared with the viral strain previously circulating in the country.

A genetic variant of TMPRSS2 may confer protection against severe COVID-19

Among a large sample of COVID-19 patients, researchers found that a genetic variant – caused by an amino acid substitution from valine to methionine – is associated with a reduced chance of severe disease.

Researchers examine susceptibility of raccoons and striped skunks to SARS-CoV-2 infection

Researchers from the University of Georgia, USA, have found some members of the superfamily Musteloidea – the group that includes badgers and weasels – appear to not only have no effects of the virus, but do little in spreading it.

Researchers report zoonotic spillover of adapted SARS-CoV-2 from minks to humans

In a recent report made available on bioRxiv* preprint server, researchers from Poland and Finland reveal a spillover event of mink-adapted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from farmed mink to humans after an extensive adaptation process.

SARS-CoV-2's amyloid-driving nucleoprotein could inform future therapeutic research

New research led by researchers at the University of California Los Angeles and the University of Texas Southwestern Medical Center in the US suggests that functional amyloid fibrils could play an integral role in developing COVID-19 treatments.

Greater cross-neutralization against UK SARS-CoV-2 variant in vaccinated individuals with prior infection

A team of researchers in Spain has observed that, of those who have been vaccinated against SARS-CoV-2, higher titers of neutralizing antibodies for the B.1.1.7 variant (originating in the UK) were present in those who had previously been infected with the virus.

Optimized SARS-CoV-2 vaccine candidate could be less reactogenic, say researchers

A new study, released as a preprint on the bioRxiv* server, reports an optimized coronavirus disease 2019 (COVID-19) vaccine candidate, which, claim the researchers, may be less likely to produce reactions like fevers. It may also have increased protective potential against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes COVID-19.

Proteomics shows SARS-CoV-2 NSP7 and NSP8 forms stable dimeric unit

A new preprint, released on the bioRxiv* preprint server, describes the structure of part of the dynamic protein-RNA complex known as the replication-transcription complex (RTC), which is crucial in the replication of the large ribonucleic acid (RNA) genome of this virus.
