Vaccine Acceptance in Pregnant Minority Women

实验性的：High Elaboration Video Arm

Women randomized to this arm will be exposed to a handheld/electronic tablet device-based video with detailed vaccine-related information designed to invoke a high level of attention to the message and thought (elaboration) while processing information.

行为的：Maternal Vaccine Education

It is assumed that the women will also receive vaccine education materials from the OB/GYN practices as part of routine care. The intervention for all three arms will be conducted during routine prenatal office visits. Participants will complete a baseline questionnaire to assess attitudes regarding vaccination and will then be randomized to one of three enrollment arms and will be exposed to an intervention designed to take no longer than 20 minutes, so that patients can complete it during the time they are waiting to be seen. While participants are completing the handheld/electronic tablet device-based intervention, the study recruiter will observe them and document dose exposure to the messages being presented. The enrolled women will be contacted a month after the expected date of delivery and a follow up interview will be conducted to ascertain their vaccination status for receipt of influenza vaccine in pregnancy and Tdap during pregnancy or immediately post-partum.

安慰剂比较：Low Elaboration / Control Arm

Women randomized to the control arm will be provided standard CDC vaccine information statements that will likely lead to low elaboration information processing.

Influenza vaccination rates in pregnancy

Data on vaccination status will be collected from participants enrolled in the main phase of the study during follow up starting one month after the expected date of delivery. We will contact healthcare providers to obtain vaccination records for those who provide written consent to release their immunization records.

Tdap vaccination rates in pregnancy

Data on vaccination status will be collected from participants enrolled in the main phase of the study during follow up starting one month after the expected date of delivery. We will contact healthcare providers to obtain vaccination records for those who provide written consent to release their immunization records.

Change in attitudes regarding vaccination

Data on attitudes regarding vaccination status will be collected from participants enrolled in the main phase of the study during follow up starting one month after the expected date of delivery.
