In COVID-19 clinical update #52, Daniel Griffin reviews differences in attack rates between children and adults, J&J vaccine phase III data, G6PD deficiency and vaccines, NIH halts convalescent plasma trial, dexamethasone in hospitalized patients, data on tocilizumab, and long COVID in children.

Paul Offit joins TWiV to discuss all things vaccine, including how COVID-19 vaccine development was accelerated, whether the vaccines are safe and efficacious, the difference between an EUA and a licensed vaccine, sterilizing immunity, herd immunity, and much more.

On this episode, a discussion of why modifying the dose schedule of the mRNA vaccines in the US is not a good idea, evidence that lower Ct values on hospital admission is associated with higher mortality, and dose-dependent response to SARS-CoV-2 infection of ferrets.
