No Intervention : Passive Control
Patients in this arm will not be sent any messages.
Active Comparator : Active Control
Patients in this arm will be sent messages encouraging them to ask about Shingrix at their upcoming appointment.
Experimental : High Risk
Patients in this arm will be sent messages informing them that they are at high risk for shingles because they are ages 50+, and encouraging them to ask about Shingrix at their upcoming appointment.
Experimental : Multi-fact
Patients in this arm will be sent messages with facts about shingles and Shingrix, and encouraging them to ask about Shingrix at their upcoming appointment.
Experimental : High Risk + Multi-fact
Patients in this arm will be sent messages informing them that they are at high risk for shingles because they are ages 50+, with additional facts about shingles and Shingrix, and encouraging them to ask about Shingrix at their upcoming appointment.

Baseline Characteristics

For the primary analysis, one patient per phone number was included to preserve independence of observations since randomization occurred on the phone number level. If a phone number was associated with more than one enrolled patient, we prioritized the first patient enrolled if enrollment dates differed, GHP members if enrolled on the same day and GHP membership differed, or selected a patient randomly if all shared the same enrollment date and GHP membership status.

If a phone number was associated with more than one enrolled patient, we prioritized the first patient enrolled if enrollment dates differed, GHP members if enrolled on the same day and GHP membership differed, or selected a patient randomly if all shared the same enrollment date and GHP membership status.
