Semantic Notes
Primarily a medical/public health term. Focus is on the process/act, not the biological state (which is 'immunity'). Often used interchangeably with 'vaccination' in general contexts, though 'vaccination' refers specifically to the administration of the vaccine, while 'immunization' emphasizes the resulting protected state.

Common Pitfalls
Translation Traps (for Russian speakers)

- Do not confuse with 'immunology' (иммунология), which is the scientific study.
Common Mistakes
- Using 'immunization' and 'immunity' interchangeably. (Incorrect: 'The immunization from the disease lasted years.' Correct: 'The immunity from the immunization lasted years.')
- Misspelling as 'immunication' or 'imunization'.
- Using a plural verb with it as an uncountable noun (usually). (Incorrect: 'Immunizations are important.' Can be correct if referring to multiple instances/vaccines. Correct (uncountable): 'Immunization is important.')
