LONDON – The U.K. Medicines and Healthcare products Agency (MHRA) has given approval for the first-in-human study of Codagenix Inc.’s COVI-VAC, a live, attenuated whole virus COVID-19 vaccine, which is engineered to be structurally identical to wild-type SARS-CoV-2, but is much slower to replicate.

LONDON – A third COVID-19 vaccine has turned in positive results in the phase III interim analysis, with Astrazeneca plc/Oxford University reporting an average of 70.4% efficacy across two dose regimens for AZD-1222. Significantly, efficacy increased to 90% in the prime-boost arm of the trial, in which volunteers received half a dose, followed by a full dose. In addition to greater protection, that will make supplies go further.

Developers of tests for the COVID-19 pandemic are deploying an increasingly wider range of test systems for molecular testing, but the FDA’s Toby Lowe said that despite the seeming interchangeability of real-time PCR (rt-PCR) systems, performance of a reference panel for a tweaked test must reflect the use of the rt-PCR system that is listed in the existing emergency use authorization (EUA).
