Monoclonal antibody prevents HIV infection in monkeys, study finds
- Details
- Category: Research
An experimental, lab-made antibody can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research published in Nature Communications shows.
The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS.
NIH researchers identify potential new antiviral drug for COVID-19
- Details
- Category: Research
The experimental drug TEMPOL may be a promising oral antiviral treatment for COVID-19, suggests a study of cell cultures by researchers at the National Institutes of Health. TEMPOL can limit SARS-CoV-2 infection by impairing the activity of a viral enzyme called RNA replicase. The work was led by researchers at NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). The study appears in Science.
How to obtain immune bovine milk to strengthen the body against COVID-19
- Details
- Category: Research
Physiologically, milk contains biocomponents that are highly protective against infections. In light of this, the AGR-149-Infectious Diseases group at the University of Cordoba's Department of Animal Health is doing research that focuses on cow's milk as a possible source of COVID-19 control. The results have been published, partially, in the journal Frontiers in Immunology.
New study may help explain low oxygen levels in COVID-19 patients
- Details
- Category: Research
A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues. The study also shows why the anti-inflammatory drug dexamethasone has been an effective treatment for those with the virus.
Parler provided echo chamber for vaccine misinformation, conspiracy theories
- Details
- Category: Research
In the early days of COVID-19 vaccine development, a new social media platform provided a place for like-minded people to discuss vaccines, share misinformation and speculate about the motivations for its development. A new study from the University of Kansas shows people flocked to Parler to discuss the vaccines in an echo chamber-type environment, and those conversations can shed light about how to communicate about vaccine efficacy during health crises.
WHO validates Sinovac COVID-19 vaccine for emergency use and issues interim policy recommendations
- Details

WHO today validated the Sinovac-CoronaVac COVID-19 vaccine for emergency use, giving countries, funders, procuring agencies and communities the assurance that it meets international standards for safety, efficacy and manufacturing. The vaccine is produced by the Beijing-based pharmaceutical company Sinovac.
Penn researchers discover drug that blocks multiple SARS-CoV-2 variants in mice
- Details
- Category: Research
The drug diABZI - which activates the body's innate immune response - was highly effective in preventing severe COVID-19 in mice that were infected with SARS-CoV-2, according to scientists in the Perelman School of Medicine at the University of Pennsylvania. The findings, published this month in Science Immunology, suggest that diABZI could also treat other respiratory coronaviruses.
