If a new born baby is immune to some illness, does that mean one of the parents must be immune?

1 doctor agrees
In brief: Mom's immunity
The fetus gains the benefit of mothers circulating antibodies (a temporary living immune factor) that is actually passed thru to baby at higher per pound levels than mom normally keeps.
Much of this happens in the final 6-8 wks of pregnancy, so premi's don't get as much. These living factors decline in the wks following birth & by 3m baby begins to make their own antibodies by experiencing illness.

In brief: Probably
All i can say is that the infant gets passive immunity from the mother. He/she does not develop active immunity (i.
e. Response to vaccination) until about 3 months.
