Interesting ?: The substance injected probably last a few weeks at most. But the response brought about by the vaccine series (all 3 shots) may last forever. I ugh eat checking titters after vaccination in high-risk patients then checking levels again every ten years. Boosters given if needed. ...Read more

Maybe lifelong but..: 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. ...Read more

Confusing question: I'll assume you had the vaccine before pregnancy or early in life. If you have proper antibody levels to the viruses in the vaccine, it protects the fetus from injury or death if you developed the disease during pregnancy. Your OB can check antibody levels prior to any pregnancy & if normal you would not need another. ...Read more
Likely a lifetime: This question has many variables, but our clinical and scientific/experimental experience with these vaccines suggests that life-long immunity is likely. This is demonstrated by current recommendations of not needing booster doses, even when titers are zero in a person who has been fully vaccinated. These vaccines produce strong anamnestic responses in our bodies to confer longterm protection. ...Read moreSee 1 more doctor answer
