The purpose of this study is to determine whether contacting the parents of adolescents overdue for routine vaccines or contacting both the parents AND adolescents overdue to routine vaccines improves immunization rates as compared to usual care.
This randomized controlled trial is a 3-armed study designed to evaluate an immunization recall system in adolescents. In the control arm (Group 1), the adolescents will receive usual care, in which they will primarily receive immunizations at annual physical exams, or as recommended by providers at urgent care visits. In one intervention arm (Group 2), the parent/guardian will receive a telephone call informing them that the adolescent is overdue for one or more immunizations (conjugated Neisseria meningitidis (MCV4) vaccine, tetanus-diphtheria-pertussis (Tdap) booster, and/or the second varicella (VZV) vaccine). In the second intervention arm (Group 3), both the parent/guardian and the adolescent will receive a telephone call informing them that the adolescent is overdue for one or more immunizations. Immunization rates will be compared between the 3 groups at a four week and a twelve month follow up period.

|---|---|---|---|
| control | No Intervention | This study arm will receive usual clinical care, but no specific intervention will be made to inform the parent or adolescent that the adolescents is overdue for a routine vaccine. | |
| Parent Only Group | Experimental | Parent Only Phone Call |
|
| Parent and Adolescent Group | Experimental | Parent and Adolescent Phone Call |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Parent Only Phone Call | Other | A telephone call will be made to the parent/guardian informing them that the adolescent has not received one or more vaccines (Td/Tdap in the past 5 years, the MCV4 vaccine, or the 2nd VZV vaccine). The phone call will include a brief informational statement about the vaccine(s) that the adolescent has not yet received. Up to 4 telephone calls will be attempted. As part of the phone call, we will offer to schedule an appointment for the adolescent to receive the missing immunization(s). We will also ask them to mail or fax to the Adolescent/Young Adult Medicine clinic records of immunizations given at other sites. |
| Measure | Description | Time Frame |
|---|---|---|
| receipt of vaccine of interest at 28 days | Vaccination records are assessed 28 days after the intervention to see if Tdap, MCV4, or the 2nd VZV vaccine were administered. | 28 days |
| Measure | Description | Time Frame |
|---|---|---|
| receipt of vaccine of interest at 1 year | Immunization records are assessed 1 year after the intervention to assess for receipt of Tdap, MCV4, and/or the 2nd VZV vaccine. | 1 year |
| receipt of other vaccines at 28 days |

Immunization records are assessed 28 days after the intervention to assess for receipt of any vaccine other than Tdap, MCV4, and the 2nd VZV.
