In listening to the Dr. Javitt/Dr Yo youtube video, he uses the words "About to announce" when discusding the two Rx partnerships.
Although I was surprised the day he mentioned during the live video, I took that to mean sometime between the day of live video showing and "by October" (his words) when he describes manufacturing 100,000 doses per month. He never gave a date for the pr release. However, he did say the Memorial Herman 21 patient release would be that next week and it was (although weirdness with the pre-release).
I find Dr. Javitt to be credible and optimistic for partnership announcements soon.
Best. Dave
