TWiV 1035: Poxvirus wars, warp speed COVID-19 vaccine rollout
TWiV dissects a study of COVID-19 vaccination which shows that the timing of initial rollout affects disease outcomes more substantially than final coverage or degree of socioeconomic disparity, and discovery of a novel cellular defense comprising a nuclease that is activated by poxvirus infection and cleaves a specific tRNA molecule to inhibit protein synthesis.
