Uh, I don't know if I should mention this or not... I had two small boy twins who every time they received a vaccination would go into convulsions within hours. I don't know if you have ever seen two 6 month-olds convulsing but it was pretty frightening for a young parent. After a discussion with the pediatrician, we tried giving half doses. Same effect. The final decision was that potential damage from convulsions trumped protection from small pox. Long story short, you aren't fully vaccinated.
