Summary

This trial will assess the effectiveness of a tailored message intervention on decreasing infant undervaccination.

Detailed description

This intervention is based on the concept of "message tailoring," whereby each mother is provided with individually customized vaccine- related information that addresses their unique concerns, values, questions and logistical barriers. Message tailoring is an evidence-based health messaging strategy that has been shown to improve compliance with a wide variety of preventive health care behaviors among diverse patient populations. In this three-armed trial the investigator will examine how providing mothers with multiple "doses" of a tailored versus untailored version of our intervention compares with "usual care" for the impact on infant under-vaccination. Secondary outcomes will include maternal vaccine-related attitudes (including level of vaccine hesitancy), alignment of maternal values with provider recommendations, and self-efficacy for overcoming logistical barriers to vaccination.

Interventions

Type	Name	Description
BEHAVIORAL	Tailored	Pregnant women will be recruited to the study. The intervention will be delivered to participants prior to the child's 2 month well child visit, when the child is between 4 and 6 months of age, and when the child is 10-12 months of age. The first intervention occurs at enrollment in the study. Participants in the tailored intervention arm will receive vaccine information tailored specific to her concerns and values at each intervention point.
BEHAVIORAL	Untailored	Pregnant women will be recruited to the study. The intervention will be delivered to participants prior to the child's 2 month well child visit, when the child is between 4 and 6 months of age, and when the child is 10-12 months of age. The first intervention occurs at enrollment in the study. Participants in the untailored arm will receive vaccine information at each intervention time point, but it will not be tailored to her specific concerns.
