I found some time ago a Chinese website for clinical trials and I could get results for Covid vaccines using google translate. However, I don’t know their rules about trials registration.

I should admit that I am not sure about the rules in US neither, it looks like phases I don’t have to be registered and that they can register it 21 days after the first patient. Maybe someone is more courageous than me to read the details, I just gave up checking it. I guess that if any information is posted, the PPS will move and we will know somehow. I don’t plan adding to my position anyway, I am just waiting (and trying to relax).
