I’ve heard about these MCA treatments in articles but am surprised to hear in these comments about it actually already being in use.

My father is an immunocompromised transplant patient and has been isolating now since the start of the pandemic. His first two vaccines had no antibody response and we will get results on his third dose in just over a month from now.

The situation has been really difficult for us as a family and he’s not had human contact this whole time (lives alone, I’m in another country). His renal consultant and local NHS consultants offer no hope or mention of MCA treatment. Has anyone more information on this in the UK?
