Scientists develop a new vaccine approach for HIV

Unlike so many other deadly viruses, HIV still lacks a vaccine. The virus--which continues to infect millions around the world--has proven especially tricky to prevent with conventional antibodies, in part because it evolves so rapidly in the body.

Genetic modification in ‘coat’ of fatal brain virus may allow it to escape antibodies

A genetic modification in the 'coat' of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers.

Sinovac Biotech's COVID-19 vaccine candidate triggers immune response

Now, Sinovac Biotech's candidate vaccine, CoronaVac, has been found to induce an immune response in healthy adults aged 18–59 years, 28 days post-vaccination. However, the level of antibodies generated was lower than in people who had recovered from the illness.

Antibody combinations may be more effective at preventing, treating COVID-19

Pairs of antibodies may be more effective than single antibodies at preventing and treating COVID-19, according to a new study by researchers at the University of North Carolina at Chapel Hill and The Rockefeller University in New York.

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.

Texas Biomed awarded $1 million to evaluate MAb therapeutics for COVID-19

Texas Biomedical Research Institute in San Antonio, Texas, was awarded $1 million from the Bill & Melinda Gates Foundation to test the efficacy of human monoclonal antibodies (MAbs) for the treatment of SARS-CoV-2 infection.

Seroprevalence meta-analysis predicts 643 million already infected by SARS-CoV-2 globally

A recent systematic review and meta-analysis conducted by a team of international scientists reveal low seroprevalence of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the general population.

Detectable SARS-CoV-2 antibodies 120 days post-infection in Chicago case study

In a recent study, a team of researchers at Northwestern University, USA, had found that nearly 20 percent seroprevalence in the United States metropolitan site, Chicago, over the summer, during a period when lockdown restrictions were eased. They found that three-quarters of seropositive individuals retained detectable antibodies for at least 120 days or four months.

SARS-CoV-2 immunity can last over six months, study finds

US-based scientists have released a study on preprint server bioRxiv*, titled “Immunological memory to SARS-CoV-2 assessed for greater than six months after infection,” contributing to the enormous research effort currently underway in this area.

UK’s COVID-19 vaccine shows similar safety and immunogenicity results in healthy older adults

The UK's vaccine against SARS-CoV-2 shows similar safety and immunogenicity results in healthy older adults (aged 56 years and over) to those seen in adults aged 18-55 years.

Scientists discover potential strategy to prevent inflammation in COVID-19 patients

The COVID-19 pandemic continues to cause significant illness and death while treatment options remain limited. St. Jude Children's Research Hospital scientists have discovered a potential strategy to prevent life-threatening inflammation, lung damage and organ failure in patients with COVID-19. The research appeared online in the journal Cell.

New understanding of glycan signatures of the SARS-COV-2 S1 spike protein

A team of scientists from the University of Oxford, UK, has revealed that site-specific glycosylation differs between spike proteins derived from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and a viral vector-based vaccine candidate.

"Escape mutations" could help SARS-CoV-2 evade immune attack

Researchers in the United States have identified mutations within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – that can reduce antibody binding to the virus, potentially mediating its escape from immune attack.

COVID-19 during pregnancy can cause placental inflammation and impaired immunity

A new study conducted by a team of researchers at Johns Hopkins University, USA, has observed how pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show stunted antiviral immune responses.

Severe COVID-19 complications linked to gut barrier breakdown

A new study claims that severe COVID-19 is caused by a positive feedback loop triggered by systemic inflammation and mediated by abnormal gut permeability. This finding could potentially help open up new avenues of treatment.

Government-funded scientists laid the groundwork for billion-dollar vaccines

When he started researching a troublesome childhood infection nearly four decades ago, virologist Dr. Barney Graham, then at Vanderbilt University, had no inkling his federally funded work might be key to deliverance from a global pandemic.

Children in Melbourne family developed COVID-19 immune response after exposure to virus

Children in a Melbourne family developed a COVID-19 immune response after chronic exposure to the SARS-CoV-2 virus from their parents, a new case report has found.

Study: e-cigarette users have increased susceptibility to flu, COVID-19

In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease.

Immunological memory can protect people against new infection after COVID-19 recovery

Until now, it was unclear whether a survived SARS-CoV-2 infection or COVID-19 leads to persistent immunological memory and thus can protect against a new infection.

Fatal chain reaction in Alzheimer's disease starts much earlier than commonly assumed

Alzheimer's disease develops over decades. It begins with a fatal chain reaction in which masses of misfolded beta-amyloid proteins are produced that in the end literally flood the brain.
