I took ds3 for his thrid set of jabs today. He is 10 months old but I have delayed them all and done them with larger gaps so it was the one he would have had at 4 months. Two hours later he came out in blisters. I took him back to the GP who said it was unrelated to the immunisation and was just chicken pox. It has developed since, and I would agree.
So, how on earth will his immune system cope? I don't normally like them to be immunised if they even have a cold let alone chicken pox!
