Summary

This trial is taking place in Los Angeles, CA at clinics 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: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and >65 yrs. (63%). The investigators will assess the effectiveness and cost-effectiveness of 1, 2, 3 MyChart R/R messages as compared to the standard of care control (no messages).
