Reducing Delay in Vaccination of Children: Logistic Barriers

Parents of children less than 11 months of age will be identified as delayed or missing
vaccinations due to logistic barriers in the Kaiser Permanente Colorado population. Parents
identified will be randomized to the intervention arm or the usual care arm. Those in the
intervention arm will receive automated reminders for the 6 month and 12 month vaccine
visits. Reminders will include scheduling information as well as access to a website with
vaccine and scheduling information. They will also have an opportunity to provide preferences
in how they receive the automated reminders (text, phone or email). There will be 2 reminders
before the 6 and 12 month visits and 2 after the 6 and 12 month visits. Parents will be
excluded from receiving reminders if they have received vaccines within the time frame when
they are eligible to receive another vaccine or have a well child visit scheduled.

Inclusion Criteria:

- Parents of children less than 11 months of age

- Currently enrolled at Kaiser Permanente Colorado at the time of identification

- The child is missing recommended vaccinations

Exclusion Criteria:

- Non-english speaking

- diagnosis code indicating parent vaccine refusal
