I just read an article, then checked out the PDF, and it indicates that MMR and Chicken Pox vax should not be given within 11 months of IVIG for Kawasaki Disease.
My son had IVIG in May 1995 and the MMR in October 1995. He also had his Chicken Pox vax in that time frame.
The ONLY reason for delaying LIVE vaccines such as MMR and chickenpox for 11 months after receiving IVIG is that the vaccine might
not be effective and could need to be repeated later.
