			If I do recall (and that means reading the article a third time) they're using stem cells. There should be no issue with rejection etc. in that manner. 
If a person is allergic to a vaccine it'll be a different component. (For instance, I haven't had an MMR since I was 11, I'm very allergic to it.) 
I don't think this is an issue. 
Perhaps AKA_Monet could also spill a little on the subject, after her recent discussion about cloning in another thread.
