About this study

Official title: Adolescent Vaccination Reminders Using Email

This protocol describes a study about vaccination uptake among adolescents. The purpose of the study is to determine whether parents who receive email reminders will be more likely to obtain Tdap (tetanus-diphtheria-acellular pertussis), HPV (human papilloma virus), meningococcal, and influenza vaccines for their adolescent children than parents who do not receive email reminders.

Read the detailed description

Adolescents are a reservoir population for a variety of vaccine preventable diseases (VPDs). Despite this, adolescent vaccination rates lag substantially behind national goals of 80% coverage for adolescent vaccines set forth by Healthy People 2020. This has been particularly the case for the vaccines most recently recommended for adolescents, such as the HPV (human papilloma virus) and seasonal influenza (flu) vaccines; national coverage levels in 2010 for HPV were 32% (for series completion among females only) and 35% for flu vaccine. Uptake levels for the two other adolescent-targeted vaccines, Tdap and meningococcal conjugate (MCV4) vaccines are currently at 69% and 63%, respectively.

A major barrier to increased adolescent vaccination levels is the lack of parental and provider recognition that an adolescent is due for vaccine doses. For providers, there are the dual challenges of getting adolescents to come in for annual preventive care visits and also minimizing "missed opportunities" for vaccination (i.e. clinical interactions with a patient where a needed vaccine could have been provided but was not). Reminder/recall systems are one mechanism to help address both of these challenges for providers while also informing parents about the need for adolescent vaccines.

  • Email NotificationBehavioural

    This study will use a targeted email reminder/recall intervention that addresses specific aspects of adolescent under-immunization.

Study groups in NCT01732315
Study groupRoleWhat they receive
Vaccination Email ReminderExperimentalThis group of parents in the study will receive email notifications about due/overdue vaccines for their adolescents. Vaccination records will be reviewed to identify adolescent patients in both practices who are newly eligible for a vaccine and/or overdue for a vaccine at the start of every other month. Email notifications will then be sent to the parents of these children.
Receives: Behavioral: Email Notification
Usual CareNo interventionThis group of parents in the study will not receive email notifications about due/overdue vaccines for their adolescents.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. New immunization doses

    To examine the effect of email vaccination reminders, new immunization doses of children of parents who receive email vaccination reminders, versus those who do not receive email reminders during the study period will be determined. New doses are those for any of four adolescent vaccines which are administered following the reminder notification, and are subsequently recorded following reminder notifications.

    Measured: New immunizations within 60 days of reminder notification

Secondary outcomes (2)
  1. Waived immunization doses

    To examine the effect of email vaccination reminders, waived immunization doses of children of parents who receive email vaccination reminders, versus those who do not receive email reminders during the study period will be determined. Waived doses are those for any of four adolescent vaccines for which medical, religious, or philosophical waivers are subsequently recorded following reminder notifications.

    Measured: Waived immunizations within 60 days of reminder notification

  2. Historical immunization doses

    To examine the effect of email vaccination reminders, historical immunization doses of children of parents who receive email vaccination reminders, versus those who do not receive email reminders during the study period will be determined. Historical doses are those for any of four adolescent vaccines which are administered prior to the reminder notification and are subsequently recorded following reminder notifications.

    Measured: Historical immunizations within 60 days of reminder notification

Questions about this trial

What is this clinical trial studying?

A study testing Email Notification in people with Adolescent Vaccination Status, run by University of Colorado, Denver at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

New immunization doses (time frame: New immunizations within 60 days of reminder notification). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01732315, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2015; AzTrials last refreshed its copy on 27 Oct 2026.
