According to the CDC, how often is a booster shot recommended after successful vaccination against HBV?

A booster shot is not recommended after successful vaccination against hepatitis B virus (HBV) because the primary vaccination series is designed to provide effective long-term immunity in most individuals. Typically, the hepatitis B vaccine series consists of three doses given over a specified duration, leading to the development of protective antibodies that usually last for an extended period.

According to the Centers for Disease Control and Prevention (CDC), most people who complete the HBV vaccination series will achieve protective antibody levels, eliminating the need for routine booster doses. This recommendation is based on studies showing that the immunity generated by the vaccine is durable, lasting at least 30 years for many individuals.

The other options imply a routine need for boosters or doses based on specific events, but the current guidance from the CDC clearly indicates that no booster is necessary in the absence of certain conditions, such as individuals who may be immunocompromised or at higher risk of exposure, who might require monitoring of their antibody levels. However, in a general population that has been successfully vaccinated, the consensus is that additional booster shots are not required.
