The purpose

Using desk location information and employees' building entry/exit swipe card data from a company that offered a free 2-day worksite influenza vaccination clinic, we separately identify the vaccination effects of base proximity—the inverse of walking distance between one's desk and the clinic—and functional proximity—the likelihood of passing near the clinic during the course of a normal work day (ie, days when the clinic is not open).

Provided treatments

  • Other: Functional Proximity
