Uncertain: We really are not 100% certain. Cdc feels--if high risk--test every 2 years (e.g. Vet working in rabies zone) latest who consensus is every 10 years. In general, if continued risk, recommend periodic retesting titers though immunity may persist even when antibodies are no longer detectable. Cdc rule? If the titer.
Dr. James Ferguson
Pediatrics 46 years experience
At least 2yr: After completion of a pre-exposure vaccine series, the protective antibody level lasts for at least 2 years. Boosters are only recommended if a serum titer has dropped. People with continuous exposure are advised to have titers done every 6 mo while those with occasional exposure should be tested every 2 yrs.

Sure: You literally can be allergic to anything, including any vaccine. A vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of a vaccine causing serious harm, or death, is extremely small. Serious problems from Rabies Vaccine are very rare. Several brands of Rabies Vaccine are available in the United States, and reactions may vary.

Nothing really: The Immune Globulin given soon post exposure can cause a fair amount of local pain but the vaccine is well tolerated and you do not need to avoid anything.

Well...: If you get the complete post-exposure series then the NEXT time you are exposed you are given only 2 shots and no immunoglobulin. If it has been more than 20 years since first series then the whole series will be given again.
