If you had this disease as a child you cannot catch it again. If you do not know and don't get the blood test you should get the vaccine before you travel. Two doses more than 6 months apart provide optimal protection, lifetime protection. However, at least one dose preferably 4-6 weeks but even up to the week before travel, will protect most travelers. The second dose provides the long term protection. You only need one vaccine before you travel and that will protect you during your trip. You should get a second vaccine 6-12 months after the first and then you are protected for the rest of your life.
