A newly hired dental assistant with no prior vaccination records should receive all of the following immunizations EXCEPT:
Show answer and explanation
Correct answer: B. Tuberculosis (TB) skin test (Mantoux/PPD)
For newly hired dental healthcare personnel, OSHA and the CDC recommend vaccination against: Hepatitis B (blood-borne pathogen risk), influenza (annual), MMR, varicella, and Tdap (pertussis). The TB skin test (Mantoux/PPD or IGRA) is a SCREENING TEST, not a vaccination — it detects exposure to Mycobacterium tuberculosis but does not immunize against it. While TB baseline testing is recommended for new healthcare workers, it is not a mandatory vaccination. The question asks about mandatory vaccinations, so TB testing (not a vaccine) is the exception.
