My son is now 7 1/2. He has not received any vaccines up until now. Tomorrow we have an appt with his pediatrician and I had asked for him to begin the tetanus vaccines. The dr asked if I was ok with the pertussis and diptheria being included as that's what they have. But now I'm getting nervous about it. Should I be? I've read about the pertussis causing more serious reactions in older children - should I ask for a different vaccine?
He's been an extremely healthy child - I'm a bit fearful that starting any vaccines will throw off his immune system. Maybe I'm over reacting?
