fouremm - I think you stated it fine regarding trials. The articles written lately were regarding preclinical research which in my uneducated scientific mind is a far cry from clinical human trials. I would surmise preclinical research is ongoing all of the time, these two just showed some promissing collaborative research with some research partners. I would say we have not started any COVID-19 trials unless they have started in recent weeks and we haven't been told. That is just my take on it. That is my thoughts on the difference between research and trials.
