Here, this came out six hours ago, it explains all three variations depicted in the PV video. Towards the end they also explain the guy told PV he has no scientific background, which would explain why they can't get exactly what they were looking for out of him. He doesn't even work for Pfizer, he's a consultant, not even a scientific consultant. They explain in the article what he does do, it's at the business end not the scientific end. From the looks of it he appears to be the most honest person in the video, he was out on a date and was trying to impress someone. As much as you are going to hate this but from Pfizers explanations in their release they come out the second most honest, that leave PV out there promoting hyperbole for clicks but hey they got Marco Rubio believing it so don't feel so bad. Another interesting but alarming aspect to the article is that it's not illegal to perform privately funded GOF in the US. I did not know that.
