Is the 3rd DTaP shot at 18 months really the worst?

Question

And:
Do all toddlers nowadays get the HIB?

Or maybe it's the fourth, I can't remember. She's due in a few weeks though.

Answer 1

I had no idea that some of them were worse than others. I'm going to keep reading this question to see what others say. My baby is almost 15 months and will be getting her third in a few days. YIKES!!! Teething AND immunizations!!!! You know, the pain doesn't really stop after the birth......

Answer 2

My son already had three dtaps and he's only 7 months. The more vaccines you have the less reaction the body has to them, since there already are immunities to the agents.
