Introduction
Hepatitis B refers to hepatitis B virus infection, and a booster shot refers to the hepatitis B vaccine booster. A hepatitis B antibody level of 109 mIU/mL generally does not require a hepatitis B vaccine booster. Hepatitis B antibodies are specific antibodies produced by the immune system to protect the body against hepatitis B virus infection, and they can be classified into hepatitis B surface antibody, hepatitis B core antibody, and hepatitis B e antibody.
HBV refers to hepatitis B, and a booster shot refers to a hepatitis B vaccine booster. A hepatitis B antibody level of 109 mIU/mL generally does not require a hepatitis B vaccine booster.
Hepatitis B antibodies are specific antibodies produced by the immune system to defend against hepatitis B virus infection. They can be classified into hepatitis B surface antibody (anti-HBs), hepatitis B core antibody (anti-HBc), and hepatitis B e antibody (anti-HBe). Testing for these antibodies helps diagnose whether a hepatitis B infection is present, assess disease progression and prognosis, and determine whether an individual has been infected.
A hepatitis B vaccine booster involves receiving another dose of the hepatitis B vaccine after the initial vaccination series to strengthen immunity. A hepatitis B surface antibody level above 10 mIU/mL is considered sufficient to provide protective immunity. Therefore, with a surface antibody level of 109 mIU/mL, immunity is already adequate, and a hepatitis B vaccine booster is not necessary.
In addition, individuals with hepatitis B should follow a daily diet rich in high-quality protein, low in fat, and high in vitamins. They should consume more high-protein foods and vitamin-rich vegetables and fruits. It's also important to ensure adequate sleep and avoid staying up late. If any discomfort occurs, prompt medical attention is recommended.
