The Hepatitis B vaccine primarily targets the prevention of infection caused by the Hepatitis B virus. Vaccination works by stimulating the immune system to produce antibodies against the virus, which helps protect individuals from becoming infected if they are exposed to it in the future. This proactive approach to health is a core component of public health strategies aimed at controlling the spread of infectious diseases.

The focus of the vaccine is on preventing the onset of Hepatitis B, which can lead to serious health issues such as liver disease, cirrhosis, and liver cancer if contracted. In contrast, options related to treatment of existing conditions or reduction of symptoms pertain to management rather than prevention. The improvement of overall health, while a potential indirect benefit of vaccination, is not the primary purpose of the Hepatitis B vaccine itself. Thus, the correct answer emphasizes the vital role vaccines play in stopping infections before they start, demonstrating their importance in maintaining public health.
