Short Message Service Reminders to Parents for Increasing Adolescent Human Papillomavirus Vaccination Rates in a Secondary School Vaccine Program: A Randomized Control Trial.

Purpose: In Victoria (Australia), the human papillomavirus (HPV) vaccine is delivered within a state-wide secondary school vaccine program, administered by local government. This study aimed to test the hypothesis that sending a short message service (SMS) reminder to parents who had consented to their child's receiving the HPV vaccine would lead to greater uptake of the vaccine within the program. The secondary aim was to assess the effect of self-regulatory versus motivational message content in the SMS.

Communication-based interventions for increasing influenza vaccination rates among Aboriginal children: A randomised controlled trial.

Background: In Australia, the influenza vaccine is funded for Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) children aged 6 months to <5 years old. In Victoria, only 2% of Aboriginal children are vaccinated against influenza.

Objective: To evaluate whether sending a letter or sending a pamphlet directly to parents/guardians would improve influenza vaccine uptake amongst Aboriginal identified children.
