Aytu BioPharma is a small company bringing UV light into the body, and the early trials on COVID last year showed it worked. The same was true for Hydroxychloroquine too. You fell for propaganda.
Maybe UV could help in some way, but was this ever going to be a real solution? I highly doubt Aytu BioPharma was in a position to deliver anything meaningful at the volume and time-scale required.
Trump simply had no clue what a workable solution looked like. He broadcast to the world as the American President the ideas of the most recent crazy to have his ear (or one that he read on Twitter), and then got a bruised ego and doubled down when shown his ideas were worthless.
No propaganda there.
