I think what they do is use training mannequins as stand-ins for the sake of a picture because it's a bit difficult for a photographer to have a hospital patient to sign a waiver. This seems to happen quite a lot. Of course, omicron is BS, but if you've known anyone who was a photographer, they typically have to ask permission to use a photo of themselves for privacy reasons. The stupidity is that they do not make a disclaimer for these photos. The news media pretty much blurs the line of propaganda on a regular basis.
