Researchers identify molecular determinants of prolonged COVID-19 post-infection

In a recent study published in the journal Natural medicineinvestigators presented a whole-transcriptome assessment of changes in blood gene expression that occur in acute COVID-19 (coronavirus disease 2019) and are associated with PASC (post-acute sequelae of COVID-19), commonly known like prolonged COVID-19. PASC comprises a wide range of symptoms such as fatigue, dyspnea, and taste/smell … Read more

Covid nasal sprays could one day stop the virus from replicating or entering the body

We have vaccines to boost our immune response to SARS-CoV-2, the virus that causes Covid. We have medicines that you can take at home (and in the hospital) to treat Covid. Now the researchers are trying something new. They want to develop drugs that stop the virus from entering the body in the first place. … Read more

How SARS-CoV-2 immune responses vary by population due to environmental and genetic factors

People infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show a wide range of clinical variations, from asymptomatic infection to fatal disease. In a recently published study on the bioRxiv* preprint server and an international team of researchers investigated the genetic, immunological, and evolutionary factors that determine the large variability observed in the clinical … Read more

A large COVID vaccination study found that thrombosis and thrombocytopenia are very rare complications.

In a recent nature communications In a journal article, investigators determine rates of thrombosis, thrombocytopenia, and thrombosis with thrombocytopenia after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination and infection. These rates were compared to background (expected) rates assessed in the UK general population. To study: Thrombosis and thrombocytopenia following vaccination and SARS-CoV-2 infection in … Read more

Will the flu and RSV always be so bad?

In the northern hemisphere, this year’s winter has not yet begun. But Melissa J. Sacco, a pediatric intensive care specialist at UVA Health, is already dreading the arrival of the one that could follow. For months, the ICU where Sacco works has been packed with children amid an early surge of respiratory infections. across the … Read more

Novel nasal vaccine approach induces potent lung immunity and protection against SARS-CoV-2

Researchers at the Centenary Institute and the University of Sydney have developed a new nasal vaccination strategy that induces potent lung immunity and protection against the SARS-CoV-2 coronavirus. The new vaccine approach has been successfully tested in mice and has the potential to be a powerful tool to improve protection against COVID-19 infection and minimize … Read more
