Patients who were vaccinated 10 to 15 years ago, especially those who were vaccinated as children, may not be adequately protected. 2  For patients with this history who are at moderate to high risk of hepatitis B infection consider quantitative hepatitis B antibody measurement to determine protective immunity.
The simple answer to âHow long does a hepatitis B vaccine last?â is that the full course of a Hepatitis B vaccine includes three vaccinations that may be enough to last for a life time. The second dose of this series should be given one month after the first one, and third dose should be 6 months after the first one. These vaccines can be given with other vaccines esp. Hepatitis A + B. It is also important to realize that normally protective antibodies induced with hepatitis B vaccine lasts up to 15 years.
