Infection Control · single question
Which of the following represents an ELIMINATION control in the hazard control hierarchy?
Show answer and explanation
Correct answer: C. Vaccination of patients and staff against infectious diseases
Vaccination is classified as an Elimination control in the dental/healthcare setting — it eliminates the pathogen as a viable threat to the vaccinated person, effectively removing the hazard of disease transmission. This is one of the most effective and highest-level interventions. Some sources may classify it as Substitution, but in dental infection control, vaccination is consistently taught as Elimination.
