I was thinking about the pan-coronavirus comments

I was thinking about the pan-coronavirus comments in some of the more recent PRs and how fortunate we are to have had the RBL testing done to show B's potential effectiveness for viruses (something we did not know last year at this time). It occurred to me that B may be effective for any enveloped virus based upon it's piercing of the envelope MOA. The link below suggests there are a lot of them that B may be able to treat. I had no idea there were that many....if the current trial confirms the RBL testing, why would any of these be off the table?
