1 Understand that hepatitis B vaccination-induced protective antibodies can last for up to 15 years, but appear to fall off over time.2  Patients who were vaccinated 10 to 15 years ago, especially those who were vaccinated as children, may not be adequately protected. 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.
In studies of the four vaccines used for hepatitis A, nearly 100% of all adults who receive one develop protective levels of antibodies within one month of receiving a single dose. In addition, eight years after receiving two or more doses, 99% to 100% of vaccinated individuals were still fully protected. Results are similar for the hepatitis B vaccine, and experts estimate that both vaccines will give immunity for up to 20 or 30 years and possibly for life. As with all medications, there is the potential for side effects. But the safety record of both vaccines is outstanding.
