Potential massive moves There is so much that we've been doing. Perhaps one of the biggest things we announced was the start of some testing in a BSL Four lab - and there are less than 30 of these facilities globally - which has a very strict control for viral outbreaks. Importantly, in this trial we're testing the original COVID-19 variant and then we're also testing the South African variant and Brazil variants. We are expecting news on that trial any day now, for its speed and efficacy for clearing COVID-19 and it will inform dosing and toxicity applications in human trials, which are pending, so really cool progress.
