Protection of upper respiratory tract will require vaccines that mimic natural infection by SARS-CoV-2

Recently, a team of researchers studied the transmission modes of SARS-CoV-2 and the protection against re-infection in ferret models in work published on the preprint server, bioRxiv.

Mild COVID-19 disease may trigger long-term immunity

Researchers in the United States have conducted a study showing that individuals who have recovered from mild coronavirus disease 2019 (COVID-19) developed sustained protective immune memory against the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Penn State researcher to study how vitamin D regulates host immunity to viral infection

Funding from the National Institutes of Health will enable a Penn State researcher to study whether vitamin D supplementation could help people ward off or reduce symptoms caused by COVID-19.

The role of micro-RNA in SARS-CoV-2 infection and COVID-19

A team of researchers based in Iran have explored the role of micro-RNA in COVID-19. Their study titled, “The emerging role of microRNAs in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection,” was published in the latest issue of the journal International Immunopharmacology.

Researchers recommend antibody cocktail to tackle SARS-CoV-2 mutations

A new study released on the medRxiv* preprint server indicates that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic – is developing multiple mutations that affect neutralization by antibodies.

Biosensor assay SARS-CoV-2 antibody test may predict COVID-19 severity in patients

Researchers in New York, USA, have found an association of mortality with an early humoral response to SARS-CoV-2 infection within the first few days after onset of symptoms (DAOS), using a highly sensitive and automated testing-on-a-probe (TOP) biosensor assays for SARS-CoV-2.

Mauritian Prime Minister calls upon world leaders to ensure fair distribution of Covid-19 vaccines

Mauritian Prime Minister Pravind Jugnauth calls for Covid-19 vaccines to be ‘distributed fairly’ amid fears that some parts of the world might be left behind in the dash for coronavirus immunity.

New technology can provide immunization against infectious diseases

A single-use, self-administered microneedle technology developed by UConn faculty to provide immunization against infectious diseases has recently been validated by preclinical research trials.

SARS-CoV-2 spike deletion mutations may evade current vaccine candidates, study finds

A thought-provoking new study reports that the anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike antibodies elicited by natural infection may not be able to neutralize emerging strains that display deletion mutations in their genomic RNA.

Chicago seroprevalence study shows COVID-19 cases 16 times higher than currently predicted

A startling new case study of Chicago, led by a team of researchers at Northwestern University in Illinois, USA, suggests a 16-fold higher incidence of SARS-CoV-2 infection than previously thought. This is judging from seroprevalence (antibody presence blood testing) figures, rather than the number of RT-PCR-positives reported there (via swab sample testing of symptomatic patients).

SARS-Cov-2 antibodies are detected up to 3 months after infection, shows study

A new study in health care workers led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa" Foundation and the Hospital Clínic of Barcelona, shows that IgA and IgM antibodies to SARS-CoV-2 decay quickly, while IgG antibody levels are maintained for at least three months after infection.

23 Nov 2020

Study suggests neutralizing SARS-CoV-2 antibodies offer protection against reinfection

A new study published in November 2020 on the preprint server medRxiv* indicates that the chances of symptomatic infection are indeed much lower among the population with antibodies to the virus.

Analysis shows social distancing helped reduce nosocomial SARS-CoV-2 transmission in London

Recently, a team of researchers from the King's College London, Guy's and St Thomas' NHS Foundation Trust, and St Thomas' Hospital, London analyzed comprehensive epidemiological and viral nanopore sequence data from 574 patients with SARS-CoV-2 infection confirmed by a PCR test in March 2020.

Researchers investigate SARS-CoV-2 transmission chain dynamics in the Nordic countries

To date, the coronavirus disease (COVID-19) pandemic has affected over 58.52 million individuals and led to more than 1.38 million deaths worldwide. Second waves of the pandemic are still ongoing in many countries with a massive impact on health care systems and economies.

Study characterizes early chains and patterns of COVID-19 transmission in France

By using data from epidemiological investigations and contact-tracing efforts during the initial phase of the coronavirus disease (COVID-19) epidemic in France, researchers were able to appraise secondary clinical attack rates and factors associated with the risk of a contact becoming a case. Their findings are currently available in a medRxiv preprint paper.

Research reveals T-cell abnormalities in severe COVID-19 cases

There is an idea within the coronavirus research field that there is some kind of T cell abnormality in critically ill COVID-19 patients, but specific details have not yet been clarified.

20 Nov 2020

Scientists explain potential reasons for SARS-CoV-2 re-infection

A study, which was published in the journal New Microbes and New Infections, focused on the possible reasons for SARS-CoV-2 reinfection.

Trump’s lame-duck status leaves governors to wing it on COVID

Not long after the world learned that President Donald Trump had lost his reelection bid, states began issuing a new round of crackdowns and emergency declarations against the surging coronavirus.

Study provides new way to develop unconventional anticancer strategies

There is considerable interest in a new class of anticancer molecules that is currently still under investigation termed the cationic antimicrobial peptides (AMPs).

Mosaic RBD nanoparticles elicit neutralizing antibodies against SARS-CoV-2

The researchers show that the mice immunized with homotypic or mosaic nanoparticles produced broad binding and neutralizing responses, in contrast to plasma antibodies elicited in humans by SARS-CoV-2 infection. The RBD nanoparticles induced cross-reactive IgG responses in the immunized mice.
