By Jennifer Boggs
Arcturus Therapeutics Holdings Inc. reported that ARCT-154, its self-amplifying mRNA COVID-19 vaccine, showed efficacy of 55% against infection and 95% efficacy against severe disease, meeting the primary and key secondary endpoints of the ongoing phase I/II/III trial.

April 19, 2022
By Mark McCarty
The U.S. FDA’s device center reported April 18 that it has revoked the emergency use authorizations (EUAs) for five tests for the SARS-CoV-2 virus, a seemingly significant reduction in the inventory of tests for the COVID-19 pandemic.
