Vincent and Brianne review the need to better understand T cell responses to SARS-CoV-2 infection to better inform public health decisions, and how IL-1 and IL-1ra are important regulators of the inflammatory response to RNA vaccines.
TWiV reviews a seminal paper showing that chemically modified bases in RNAs suppress recognition by Toll-like receptors, a finding that that was essential for the development of COVID-19 mRNA vaccines.
Paul Offit returns to TWiV to discuss new CDC guidance on J&J vaccine, why children should be immunized against COVID-19, and whether or not booster doses are scientifically justified.
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.
TWiV reviews the impact of vaccination on SARS-CoV-2, the latest information on Omicron, West Nile virus transmission by organ transplantation, and why a 16 week interval between doses of BNT162b2 vaccine is better than a shorter interval.
A TWiV duo reviews how SARS-CoV-2 attacks the olfactory mucosa but spares the olfactory bulb, vaccination with BNT162b2 induces virus-specific stem cell memory T cells, and development of an oral protease inhibitor for the treatment of COVID-19.
Greg Zuckerman joins TWiV to discuss his book that explores the race to produce COVID-19 vaccines, with insights into the companies, scientists, and executives involved and the rivalries, ambitions, ego, and a desire to save the world.
TWiV reviews how a novel technology enabled development of COVID-19 mRNA vaccines, and discovery of a proton gradient and an incomplete TCA cycle in a giant. virus.
The meteorologicomaniacs discuss the COVID-19 pandemic global death toll, effectiveness of vaccines against the delta variant, and how analysis of ancient viral DNA reveals that two pathogenic human viruses were brought into Mexico during the transatlantic slave trade.
TWiV reviews SARS-CoV-2 infection of wild white-tailed deer in the US, mRNA vaccine-mediated protection by spike-specific T cells before detection of neutralizing antibodies, and recovery from SARS-CoV-2 infection in T-cell depleted rhesus macaques.
