Immunization plays a crucial role in infection control primarily by preventing the spread of infectious diseases. When individuals receive vaccines, they build immunity against specific pathogens, which reduces the likelihood of infection in the vaccinated individuals and, importantly, decreases the overall transmission of these diseases within the community. This herd immunity effect protects those who cannot be vaccinated, such as individuals with certain medical conditions, by significantly lowering the prevalence of disease in the population.

While mitigation of symptoms is beneficial, the primary goal of immunization is to prevent infections before they occur. Additionally, while immunization can lead to a decreased use of antibiotics, it does not eliminate their need entirely, as antibiotics are still necessary to treat bacterial infections after they occur. Lastly, although vaccines can enhance immune responses, the main focus in the context of infection control is their preventive capacity in halting disease transmission. Thus, the contribution of immunization to infection control is most accurately reflected in its ability to prevent the spread of infectious diseases.
