What is the difference between immunization and vaccination?

Immunization refers to the general process of gaining immunity, or protection, against disease-causing agents. Vaccination is more specific, referring to the process of receiving a vaccine. More broadly, immunization further protects vulnerable groups through a phenomenon known as herd immunity, in which a large proportion of a population effectively repels an infectious agent, helping restrict its spread to individuals who cannot be vaccinated or are highly susceptible to infection.
