In COVID-19 clinical update #104, Daniel Griffin reviews effectiveness of mRNA vaccines among children, number of children affected by disease, accuracy of rapid antigen tests, CDC guidance for prevention strategies, monoclonal antibody effectiveness, predicting progression to severe respiratory failure from pneumonia, risk of long COVID after two vaccine doses, and peripheral neuropathy in long COVID.
TWiV discusses whether or not Omicron should be designated a new serotype of SARS-CoV-2, and the finding that amino acid changes that adapt SARS-CoV-2 to mink or ferret do not increase fitness in the human airway.
In COVID-19 clinical update #103, Daniel Griffin covers immunocompromised people, hospitalization of children, vaccine usage update, Omicron and cross-reactive neutralizing antibodies, reinfection prevents disease in hamsters, repeated infections with endemic coronaviruses, global burden of antimicrobial resistance, ivermectin not protective in hamsters, and Omicron evades therapeutic monoclonals.
TWiV reviews epidemiological and experimental evidence that infection with Epstein-Barr virus leads to the production of antibodies against a viral protein that cross-react with a human protein, leading to multiple sclerosis.
In COVID-19 clinical update #102, Daniel Griffin reviews children and COVID, effectiveness of maternal vaccination, vaccines for immunocompromised, primary care physicians and vaccination rates, booster safety among adults, placentitis, azithromycin, oral Nirmatrelvir, Omicron antibody evasion, EUA for bebtelovimab, IL-1 blocking agents, thromboprophylaxis, effectiveness of vaccines against long COVID, and risks of mental health outcomes.
TWiV reviews an experimental, intranasally administered SARS-CoV-2 vaccine that utilizes adenovirus vectors to deliver three viral proteins and induces immunity to ancestral and variant isolates.
Amy returns to TWiV to discuss her work on the identification of cross-reactive antibody responses among diverse enteroviruses, and the implications for our understanding of viral pathogenesis and seroprevalence studies.
In COVID-19 clinical update #101, Daniel Griffin discusses children and COVID, human challenge study results, effectiveness of mask use, Omicron boost in macaques, mucosal vaccine candidate, long-term cardiovascular outcomes, and global vaccine perceptions.
Monica, John, David, and Marc join TWiV to discuss their work on identifying cryptic SARS-CoV-2 lineages in New York City wastewater, and understanding whether they were shed from humans or other animals.
TWiV reviews the results of a study in which 36 volunteers were infected with SARS-CoV-2, and what was learned about the kinetics of virus reproduction in the nose and throat, development of symptoms, and reliability of lateral flow antigen assays.
