Janssens’ COVID-19 vaccine effective against SARS-CoV-2 Delta variant

Researchers in the Netherlands have conducted a study showing that Janssen’s Ad26.COV2.S coronavirus disease 2019 (COVID‐19) vaccine was effective against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among eight individuals.

Is there a link between circadian rhythms and COVID-19 severity?

This study showed that the time of day of SARS-CoV-2 infection could impact the severity of the viral infection and the host immune response.

New study investigates alternative ways to prevent, treat kidney infections

Ten IU School of Medicine researchers out of a team of 11 scientists, are responsible for the findings of a new study they conducted to investigate alternative ways to treat kidney infections.

How does dexamethasone therapy work in severe COVID-19?

The possible mechanisms that result in dexamethasone being an effective drug against severe SARS-CoV-2 infection are investigated in a new study. The paper’s authors advance the hypothesis that SARS-CoV-2 infection induces cell-specific insensitivity to glucocorticoids, possibly as an unintentional result of the viral replication cycle.

Antibody response following SARS-CoV-2 mRNA vaccine is greater than natural infection

Researchers in the United States have provided the first evidence that messenger RNA (mRNA)-based vaccines against severe acute respiratory coronavirus 2 (SARS-CoV-2) induce a broader array of antibody subtypes against the viral spike protein than natural infection does.
