To the Editor: The Research Letter by Dr Chapman and colleagues1 demonstrated that an opt-out strategy for influenza immunization significantly improved vaccination rates compared with an opt-in approach. Influenza immunization rates for health care workers have historically been low,2 despite strong recommendations from national organizations. Any method that will improve these rates is potentially useful.
