Summary

This trial is taking place in Los Angeles, CA among patients from primary care practices within the UCLA Health System. Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low. The investigators will assess the effectiveness of message-framing (gain-framed, loss-framed messages, no messages), as well as the effectiveness of a pre-commitment prompt (pre-commitment prompt, no prompt) asking about a patient's intention to get the influenza vaccination, using a 3 x 2 factorial design.
