In COVID-19 clinical update #96, Daniel Griffin reviews Omicron in South Africa, rapid antigen tests, viral coinfections, isolation and quarantine, saliva preferred for Omicron, risk factors for severe disease in vaccinated, Paxlovid dosing, and long COVID.
TWiV kicks off 2022 with a review of the virology highlights of 2021, from three virologists, one immunologist, a science writer, and a partridge in a pear tree.
In COVID-19 clinical update #95, Daniel Griffin discusses new CDC guidelines for isolation and quarantine, EUA for Molnupiravir, children and COVID, vaccine safety in 5-11 year olds, Omicron outbreaks in Nebraska and Denmark, Baylor’s COVID vaccine, and COVID-OUT for ivermectin.
TWiV explores the impact of the intestinal virome on seroconversion after rotavirus vaccination, and implications of the ability of the SARS-CoV-2 beta variant to infect wild-type laboratory mice.
In COVID-19 clinical update #94, Daniel Griffin reviews the FDA EUA for Paxlovid, test to stay in school, immunity after infection, variants and therapeutics, quarantine and isolation guidelines, Molnupiravir in non-hospitalized patients, and convalescent serum in outpatients.
In COVID-19 clinical update #93, Dr. Griffin summarizes Omicron fitness, S-gene target failure, monoclonal efficacy against Omicron, vaccination, monoclonals, and disease in children, persistence of memory B cells in the elderly, infection and vaccine induced immunity, protection against severe illness and death by a third mRNA vaccine dose, high flow oxygen versus intubation, and therapeutic anticoagulation.
TWiV provides an update on immunity to Omicron, results of a randomized controlled trial of face masks, and a study of correlates of protection against respiratory syncytial virus infection in the upper and lower respiratory tract of nonhuman primates.
In COVID-19 clinical update #92, Dr. Griffin reviews emerging data on the Omicron variant, much information about monoclonal antibody treatment, including expansion of EUA for Lilly’s cocktail, FDA EUA for pre-exposure prophylaxis, outcomes after treatment, and investigation of subcutaneous or intramuscular administration; effect of adding immunomodulatory agents to usual care on thromboembolic events, and long COVID following infection in previously vaccinated individuals.
In COVID-19 clinical update #91, Dr. Griffin discusses final results of molnupiravir trial, Omicron variant of concern, outcomes in B-cell depleted patients, recovery in T-cell depleted macaques, peptide for induction of T cell immunity, high respiratory viral RNA loads in infants, IgA and T cells transferred to breast milk after vaccination, sensitivity and specificity of ID NOW, post-acute sequelae at 12 months, disease in low and middle income countries.
TWiV reviews why children should be vaccinated against COVID-19, increased risk of infection with SARS-CoV-2 Beta, Gamma, and Delta variant compared to Alpha variant in vaccinated but not recovered individuals, and immune correlates of protection from the mRNA-1273 vaccine efficacy trial.
