Vaccine-related standard of care and willingness to respond to public health emergencies: A cross-sectional survey of California vaccine providers

► Respondents in practices with a higher vaccine-related standard of care had a higher willing to respond index (β = 0.190, p = 0.001). ► Respondents who had participated in emergency training or actual emergency response had a higher willing to respond index (β = 1.323, p < 0.0001). ► Improving vaccine-related standard of care may be important to highlight in pandemic preparedness plans.
