This experiment is part of a megastudy with a total of ten experimental conditions and a holdout control condition to which patients will be randomly assigned. The focal comparison in this experiment is between a message encouraging vaccination that provides patients with a free round trip ride-share ride to and from any pharmacy near them and a control message telling patients that an updated COVID booster vaccine is waiting for them.
