Well I had an interesting deep dive into this forgotten therapy method, reminds me of phage therapy. Of course as even the most recent (Oct '20) paper on it says: > While there is no reason to propose mass use of UBI or ECP-based protocols against SARS-CoV-2 infection, it is certainly warranted to perform further basic studies about UBI and ECP mechanisms, and then conduct trials for specific applications including SARS-CoV-2 infection. Not that it matters really as Trump already claimed he was being sarcastic so he's already denied he meant putting UV light/disinfectant into the body. Unless he was being sarcastic about being sarcastic? I suppose if this turns out to not work he'll have been sarcastic about being sarcastic about being sarcastic ;)
