I actually think that they just don't want blood/plasma from vaccine induced antibodies, they want the real thing from natural immunity. Just like hemoglobin from measles, etc. Why would they want vaccine induced antibodies, (if there is such a thing.
This is my read on it as well. There’s a much greater range of antigenic targets with natural antibodies than just the RBD of the spike protein produced from the vax.
Additionally- convalescent plasma doesn’t really seem to be an effective treatment for covid, so I think they halted this policy already anyways.
