Which vaccine is NOT routinely recommended for healthcare workers in the United States?

The BCG (Bacille Calmette-Guerin) vaccine for tuberculosis is NOT routinely used in the United States because: (1) the overall risk of TB infection is relatively low in the US; (2) BCG vaccination interferes with tuberculin skin test (PPD) interpretation; and (3) the vaccine has variable efficacy against pulmonary TB in adults. The CDC recommends BCG only in specific high-risk situations. In contrast, Hepatitis B vaccination, Tdap (tetanus, diphtheria, pertussis), and annual influenza vaccination are all required or strongly recommended for healthcare workers including dental professionals.
