If the infant is too young to receive immunization that means they are protected by maternal antibodies, so there's nothing to worry about. The real problem you are thinking of is that the age of many vaccinations need to be moved up since maternal antibodies from vaccinated mothers wane quicker.

I think I remember something about the MMR vaccine being given at 1 year because it's less effective when given earlier, for that reason.
- nonbel 8y agoYep, that is exactly the reason vaccination is delayed. They originally tried giving them at younger ages but stopped because it wasn't working (I've never seen any report of a health danger).
