Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to understand why parents do or do not vaccinate their children and explore what information parents need to vaccinate their children. The study will test whether information about vaccinations provided during pregnancy by a health provider (VISTA intervention) may improve the possibility that a child is vaccinated on time.
