Antibody response following SARS-CoV-2 mRNA vaccine is greater than natural infection

Researchers in the United States have provided the first evidence that messenger RNA (mRNA)-based vaccines against severe acute respiratory coronavirus 2 (SARS-CoV-2) induce a broader array of antibody subtypes against the viral spike protein than natural infection does.

SARS-CoV-2 B.1.1.420 and B.1.617.1 immune escape variants reported in France

Researchers discovered the first N440K variant and the new E484Q and L452R Indian variants isolated in France in a recent study. They presented the genetic mutations in the isolated genomes and the phylogenetic tree, including these strains among different SARS-CoV-2 clades. This work is posted on the bioRxiv preprint server.

Scientists develop experimental direct-acting antiviral therapy to treat COVID-19

An international team of scientists from the Menzies Health Institute Queensland (MHIQ) at Griffith University and from City of Hope, a research and treatment center for cancer, diabetes and other life-threatening diseases in the U.S., have developed an experimental direct-acting antiviral therapy to treat COVID-19.

New imaging technique helps reveal the best antibodies for COVID-19 detection

Vaccines are turning the tide of the pandemic, but the risk of infection is still present in some situations. If you want to visit a friend, get on a plane, or go see a movie, there is no highly accurate, instant test that can tell you right then and there whether or not you have a SARS-CoV-2 infection.

SpaceX study profiles evolution of antibody response during COVID-19 infection

New research published on the preprint server bioRxiv* suggests S2-specific antibody responses are critical in recovering from mild to severe COVID-19 infection. Compared to patients who died within 28 days of their COVID-19 diagnosis, patients who produced a wide range of S2-specific responses were more likely to survive.

A possible human-to-canine transmission of SARS-CoV-2

Now, researchers at the U.S. Centers for Disease Control and Prevention (CDC) identified a case of human to animal transmission when SARS-CoV-2 was detected in a healthy poodle dog living with four family members who had COVID-19.

Moderna's COVID-19 vaccine elicits six-month antibody responses to variants

Researchers in the United States have demonstrated the long-term durability of the antibody responses elicited by Moderna’s mRNA-1273 vaccine against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Researchers investigate immune molecule that helps protect transplanted kidneys

Looking to improve organ transplant success, researchers are working to learn more about how an immune molecule, which also protects a fetus, helps protect some transplanted kidneys, and to develop a synthetic version of that molecule that could help more patients.

A promising drug delivery system for therapeutics that shut down harmful genes

Viruses attack the body by sending their genetic code -- DNA and RNA -- into cells and multiplying. A promising class of therapeutics that uses synthetic nucleic acids to target and shut down specific, harmful genes and prevent viruses from spreading is gaining steam.

Stabilizing mutations in SARS-CoV-2 immunogens improve vaccine design

Researchers in the United States have developed stabilized immunogens presenting the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that may improve the scalability of RBD-based coronavirus vaccines.

Milder COVID-19 in children may be due to higher memory B cells responses to SARS-CoV-2

A new research paper published in the journal Science explores the differences in coronavirus-specific B memory cell repertoires in children versus adults, as well as the functional importance of this discovery.

New technology tricks tumors to eliminate itself through the production of anti-cancer agents

Scientists at the University of Zurich have modified a common respiratory virus, called adenovirus, to act like a Trojan horse to deliver genes for cancer therapeutics directly into tumor cells. Unlike chemotherapy or radiotherapy, this approach does no harm to normal healthy cells.

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.

ACROBiosystems makes donations to BEI Resources, accelerating the process of attacking SARS-CoV-2 variants globally

Multiple SARS-CoV-2 variants are emerging and circulating globally; the battle against COVID-19 pandemic is still challenging. Recently, ACROBiosystems donated SARS-CoV-2 mutant proteins to BEI Resources, a NIAID funded bioresource program, joining in the collective effort in attacking SARS-CoV-2 variants globally.

Antibody to SARS-CoV-2 inhibits complement hyperactivation

Although several monoclonal antibodies against the SARS-CoV-2 spike protein have been developed and clinically tested, little is known about antibodies to the nucleocapsid protein. In a paper published recently in the journal Nature Communications, researchers report a human monoclonal antibody that targets the nucleocapsid protein.
