                        Does your friend live in Southern California?  The City of Hope was conducting experiments and trying to develop a vaccine for CMV.  This was about 2 1/2 years ago, because I was involved in it.  I was a bone marrow donor for my Brother & was called in to participate in the program for about 2 months.  At that time they were working on my blood type, but I could never find out how the study went.  I would suggest that they be contacted for any update.  I wish you well.
