Can CT scan's radiation reduce the effectiveness of rabies vaccines??

[Deejay06]

I had my rabies PEP shots last month and a day before I took the shot, I had a plain CT scan of the brain. Would it have any impact on the effectiveness of the vaccines?? I mean the radiation, can it prevent the vaccines from working properly?? Just for the reference, the vaccines I took were PVRV (prepared on vero cells). I think its just my anxiety asking questions like this but still would like to get some expert opinions. And I am sorry if this question sounds absurd. I saw a local online doctor saying that a CT scan might decrease antibody production as it results in immunosupression by emitting radiation. Asked this question online on various platforms, all of the doctors answered that it won't have any impact on the vaccines but that one doctor, he created some anxiety in my mind.
