I agree with Chandra. If at risk, I would not vaccinate at all. As it is, we have vaccinated decidedly off-schedule which we have to defend every time we go in. At 14 mos. ds had:
Hib and Polio at 5 mos. old - developed a mild rash on his back which persisted for almost 3 weeks
1st DTaP at 8 mos. old - no problems
2nd Polio at 11 mos old
2nd Hib at 13 mos. old
2nd DTaP at 14 mos. old.
I am dithering about the Prevnar at present but if and when we do that then it will be the last for a while. Since we are having such a problem with finding singles for the MMR we may do that one but not until after age 2. My brother had the German measles at age 3 or 4 and became deaf in one ear because of it so it is a sensitive subject in my family. I can't just discount the ability to vaccinate against it. DH had polio as a child and so, even though it is much less common now, we did get that one, although not the oral form.
