I was thinking something along these lines.
Perhaps the most potent psyop would be to make it appear to any rational person that he is dead, including using a crisis actor pretending to be Damar. Make it painfully obvious that something odd is going on. All the while you push the narrative that conspiracy theorists are making life hell for Damar and his family. Then at some point Damar comes out of hiding, alive and well, and basically validates what the MSM has been saying. That he made a full recovery, that it has nothing to do with the vaxx, and that conspiracy theorists forced him into hiding. Normies would love this, and few would suspect that the entire thing (or most of it at least) was orchestrated.
I know this is far out there, and I'm not saying it's likely, only that it would seem effective in making antivaxxers look bad, and that nothing would surprise me.
