About

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 comes from a patient's local pharmacy team and a control message telling patients that an updated COVID booster vaccine is waiting for them.
