In his weekly clinical update Dr. Griffin discusses the infectiousness of SARS-CoV-2 breakthrough infections and reinfections during the Omicron wave, virological characteristics of the SARS-CoV-2 XBB variant derived from recombination of two Omicron subvariants, antibody evasion properties of rising SARS-CoV-2 BQ and XBB subvariants, comparative effectiveness of third doses of mRNA-based COVID-19 vaccines in US veterans, time to negative PCR conversion among high-risk patients with mild-to-moderate Omicron BA.1 and BA.2 COVID-19 treated by Sotrovimab or Nirmatrelvir, COVID drug Paxlovid was hailed as a game-changer, what happened?, the Fc-effector function of COVID-19 convalescent plasma contributes to SARS-CoV-2 treatment efficacy in mice, SARS-CoV-2 infection and persistence in the human body and brain at autopsy, long-term cardiovascular outcomes of COVID-19, and how heart-disease risk soars after COVID — even with a mild case.
