Which disease can be prevented through immunization?

The ability to prevent disease through immunization is a key aspect of public health. Hepatitis B is indeed preventable through vaccination, which is a highly effective method of protecting individuals from this viral infection that attacks the liver. The hepatitis B vaccine is typically administered in a series of three doses and is recommended for infants, children, and adults at increased risk.

While the influenza vaccine is also important for reducing the risk of contracting the seasonal flu, it is not the same as a traditional vaccination for long-term disease prevention, as the strains of the virus change annually. Norovirus does not have a vaccine available and is mainly prevented through good hygiene practices. Measles, on the other hand, is also vaccine-preventable and is effectively controlled by the measles-mumps-rubella (MMR) vaccine. In this context, the focus is on Hepatitis B being a widely recognized prevention through immunization, making it the standout among the choices presented.
