Brief 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.

Outcome Measures
Primary Outcomes (1)
Receipt of the Annual Influenza Vaccine Among Index Patients.
Receipt of the annual influenza vaccination (between 10/2/19 - 4/1/20) among index patients. Outcomes will be assessed via vaccine data extraction from the electronic health record and external claims and pharmacy data. Index patients will be randomly selected individuals within an included household, eligible for the following groups (\<18, 18-64 non-diabetic, 65+ non-diabetic, and 18+ diabetic). One index patient per group may be selected from each household. The index patients must also be an active UCLA Health MyChart user (\>= 1 login over the last 12 months from 8/1/19, excluding activity on the user's initial profile activation date). Individuals not affiliated with any primary care practice will be excluded from the primary analysis.

Study Arms (6)
Gain-framed portal reminders + Pre-commitment Prompts
ACTIVE COMPARATORParticipants receive gain-framed reminder/recall messages regarding influenza vaccination via the patient portal and a pre-commitment prompt asking if they plan to receive the influenza vaccine in the upcoming season
Gain-framed portal reminders + No pre-commitment prompt
ACTIVE COMPARATORParticipants receive gain-framed reminder/recall messages regarding influenza vaccination via the patient portal and no pre-commitment prompt asking if they plan to receive the influenza vaccine in the upcoming season
Loss-framed portal reminders + Pre-commitment prompt
ACTIVE COMPARATORParticipants receive loss-framed reminder/recall messages regarding influenza vaccination via the patient portal and a pre-commitment prompt asking if they plan to receive the influenza vaccine in the upcoming season
Loss-framed portal reminders + No pre-commitment prompt
ACTIVE COMPARATORParticipants receive loss-framed reminder/recall messages regarding influenza vaccination via the patient portal and a no pre-commitment prompt asking if they plan to receive the influenza vaccine in the upcoming season
No portal reminder + Pre-commitment prompt
ACTIVE COMPARATORParticipants do not receive any reminder/recall messages regarding influenza vaccination via the patient portal but do receive a pre-commitment prompt asking if they plan to receive the influenza vaccine in the upcoming season
No portal reminders + No pre-commitment prompt
NO INTERVENTIONParticipants do not receive any reminder/recall messages regarding influenza vaccination via the patient portal and do not receive a pre-commitment prompt asking if they plan to receive the influenza vaccine in the upcoming season
