Even mild SARS-CoV-2 respiratory-only infection can cause long-term neurologic damage

A new bioRxiv* preprint study led by Michelle Monje of Stanford University in California finds that a mild COVID-19 infection can produce long-term neurological damage. Persistent cognitive complications are one of many symptoms of long COVID, and the latest results suggest the severity of COVID-19 induced brain fog is similar to cancer’s “chemobrain.”

Exploring waning vaccine effectiveness over time

New research provides strong evidence against waning protection against symptomatic disease from both ChAdOx1-S and BNT162b2, but points out that protection against hospitalization and death remains at much higher levels for at least 20 weeks post-vaccination.

BNT162b2 COVID vaccine 94% effective against adolescent hospitalization

A recent study revealed the effectiveness of 93% for the BNT162b2 vaccine against COVID-19 hospitalization among adolescents (12 to 18 years). This study included 179 patients at 19 sites in 16 states. The same group of researchers have extended their analysis to 31 locations in 23 states across the U.S. and recruited 266 more patients who had been hospitalized with SARS-CoV-2 infection.
