Reinfection, severe outcome more common with BA.5 variant; virus spike protein toxic to heart cells

Thu, 2022-07-28 17:38 — FNUOvviyaa
Reinfection, severe outcome more common with BA.5 variant; virus spike protein toxic to heart cells Compared with the earlier Omicron BA.2 subvariant, currently dominant Omicron BA.5 is linked with higher odds of causing a second SARS-COV-2 infection regardless of vaccination status, a study from Portugal suggests. Further, they found, in infected heart muscle cells only the SARS-CoV-2 spike interacted with so-called TLR4 proteins (Toll-like receptor-4) that recognize invaders and trigger inflammatory responses.

Hospitalized patients with severe COVID-19 during the Omicron wave benefited from a 4th vaccine shot--Israeli study

Waning vaccine-immunity and an increased incidence of COVID-19 during the Omicron outbreak led the Israeli Ministry of Health to recommend a fourth dose of BNT162b2 for high-risk individuals. This study assessed the effect of that dose for hospitalized patients with severe/critical, breakthrough COVID-19. ...

Among hospitalized patients with severe/critical breakthrough COVID-19, a recent fourth dose was associated with significant protection against mechanical ventilation or death, compared to three doses.
