Ten-fold reduced risk of workplace SARS-CoV-2 infection in seropositive essential workers

A reassuring new study supports the opening of workplaces to seropositive workers in view of the extremely low risk of reinfection observed in this cohort.

COVID-19 risks likely to shift from older adults to younger children

Within the next few years, as the SARS-CoV-2 virus becomes endemic in the global population, COVID-19 may behave like other common-cold coronaviruses, affecting mostly young children who have not yet been vaccinated or exposed to the virus, according to new modeling results.

Two-arm molecule can deplete cancer-protecting cells to promote immune responses against tumors

A two-arm molecule can effectively deplete cancer-protecting cells inside tumors, allowing the immune system to fight off tumors without becoming overactive. The finding, published online in Science Translational Medicine, could lead to new types of cancer immunotherapies.

Evaluation of mRNA vaccine responses with a surrogate SARS-CoV-2 viral neutralization assay

In the current study, the authors evaluate several different competitive ELISAs that could be used to measure serum antibodies.

COVID-19 vaccine likely protects people living with HIV, study shows

A Johns Hopkins Medicine research team has shown that people living with the human immunodeficiency virus (HIV) are likely to be protected against SARS-CoV-2, the virus that causes COVID-19, if they are fully vaccinated.

Small NIH clinical trial shows that new monoclonal antibody can prevent malaria

One dose of a new monoclonal antibody discovered and developed at the National Institutes of Health safely prevented malaria for up to nine months in people who were exposed to the malaria parasite.

COVID-19 booster shot in autumn will effectively protect against existing and future variants

Scientists at the University of Nottingham have confirmed that an autumn 'booster' dose of a Covid-19 vaccine will be an effective way to protect people from existing, and potentially future, variants of concern.

COVID-19 vaccines offer better protection than natural immunity alone

Now, the U.S. Centers for Disease Control and Prevention (CDC) reports that among people who were previously infected with SARS-CoV-2, those who were still unvaccinated are more likely to be reinfected than those fully vaccinated after prior infection.

Both mRNA vaccines protect against symptomatic disease with SARS-CoV-2 Delta variant

A new study demonstrates that the two mRNA vaccines have widely varying efficacies against the SARS-CoV-2 Delta variant.

Study defines SARS-CoV-2 antibodies associated with neutralization and effector functions

A new study explores the polyclonal antibody response to SARS-CoV-2 in greater detail.

Green spaces, especially forest, reduce COVID-19 incidence, study says

An intriguing new study reveals that the closer you are to green spaces, especially forests, the less likely you are to be infected with SARS-CoV-2.

Study shows efficacy of gamma irradiation of SARS-CoV-2 vaccine candidate in mouse model

A new study reports a more rapid method of viral inactivation in an effort to increase the appeal of inactivated viral vaccines against the COVID-19 pandemic.

Natural vs. vaccine-induced COVID-19 immunity

A new paper discusses the protection offered by immunity against COVID-19 following vaccination as compared to natural infection.

IMBA researchers may have found the "Achilles' heel" of SARS-CoV-2 virus

Researchers identify two sugar-binding proteins that impede the viral entry of circulating SARS-CoV-2 variants.

Comparative scoring system suggests possibility of global COVID-19 eradication

The global eradication of COVID-19 is probably feasible, and more so than it is for polio, although considerably less so than it was for smallpox, suggests a comparative score of technical, sociopolitical, and economic factors for all three infections, published in the online journal BMJ Global Health.

Beige fat cells mediate subcutaneous fat's brain protection from dementia

Beige is considered a calming paint color, and scientists have new evidence that beige fat has a similar impact on the brain, bringing down the inflammation associated with the more common white fat and providing protection from dementia.

New estimate of total immunity to SARS-CoV-2 in Texas

According to researchers in Texas, a lack of appropriate testing in the US has led to an underestimation of seroprevalence in the U.S., thus making it difficult to estimate population immunity to SARS-CoV-2 or vaccination.

Study shows impaired SARS-CoV-2 mRNA vaccine antibody response in individuals with chronic conditions

A recent study in Colorado used real-world data to evaluate if individuals with chronic conditions have reduced antibody response to COVID-19 mRNA vaccines. The study investigated whether some medical conditions may impact antibody response to the mRNA vaccines.

Long COVID may be due to persistent immune disturbances

A new study discusses abnormalities in the immune response following COVID-19 in samples collected from patients who have recovered from COVID-19.

COVID-19 vaccines offer better protection than natural immunity from prior infections

In today's MMWR, a study of COVID-19 infections in Kentucky among people who were previously infected with SAR-CoV-2 shows that unvaccinated individuals are more than twice as likely to be reinfected with COVID-19 than those who were fully vaccinated after initially contracting the virus.
