L.Z.
I didn't start vaccinating my 1st born till he was 2. Booby juice (breast milk) is the best thing to boost the immune system. I waited till he was a year old to introduce solids under the guidance of his pediatrician. I also use homeopathic medicine. My son is 9 years old now and has never taken a prescription medication and NEVER been on antibiotics.
Keep him/her away from parties etc. during flu season.
Dr.Feder has a list of things you can do to prepare your little one homeopathically before you vaccinate to help curtail the damage.

Just as a side note, my son has suffered some pretty horrible side effects from being vaccinated even though I did wait. If anything compromised his immune system, it was being vaccinated.
