Pneumococcal; tetanus, diphtheria, and pertussis; and influenza vaccination increased among high-risk adults in a 2-year study.

Pneumococcal polysaccharide vaccination of healthcare workers during an influenza pandemic is cost-effective from a societal perspective but not from a hospital perspective without external subsidy.

Factors significantly associated with adult vaccination rates in primary care practices were patients’ age, race, scheduled well-visit length, and nurses’ vaccination status.
