Does vaccination against hepatitis B provide immunity for life?

The hepatitis B vaccine provides long-lasting immunity in most people. However, the duration of immunity may vary from person to person, and some individuals may experience a decline in antibody levels over time. To ensure continued protection, some countries recommend a booster dose of the hepatitis B vaccine for certain populations, such as healthcare workers and those with weakened immune systems. Regular monitoring of antibody levels and consultation with a healthcare professional can help determine the need for booster doses and ensure lifelong immunity.
