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**

In addition, the anamnestic response (immune memory) remains intact in almost all persons who developed antibodies to this virus. Of interest is the fact that immunization with the cowpox virus will not protect you from getting cowpox. This was proven by Jenner in his original studies.

In brief: Yes
The vaccination is with a live cowpox virus and for most individuals provides lifelong lasting immunity.
