The Effect of Proximity on Flu-Shot Participation

Completed

Conditions studied: Influenza, Human

In brief

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).
