Don't need to be: Smallpox has been eradicated worldwide so there is no longer any need for vaccination, and no you are not immune.

The vaccination: would not infer immunity to a child that wasn't even conceived. However, it is likely that she still has immunity. A study called “Duration of antiviral immunity after smallpox vaccination.” Hammarlund E. etal (Nat Med 2003) showed that >90 % of volunteers vaccinated 25 to 75 years prior still had significant humoral / cellular immunity. ** http://www.ncbi.nlm.nih.gov/pubmed/12925846**
