Vaccine Misinformation and Its Link to Vaccine Hesitancy and Uptake in Durham (2018-2019)

Background

Vaccinations administered during pregnancy and the first year of a child’s life are crucial for preventing a myriad of potentially deadly and debilitating infections such as polio, pertussis, measles, influenza and tetanus. Despite overwhelming scientific evidence on the benefits of vaccinations, pregnant women and parents of young children often refuse to accept, or choose to space out, vaccinations for themselves or their children. This phenomenon, termed vaccine hesitancy, is blamed for several vaccine-preventable outbreaks in the U.S., including the 2017 measles outbreak in a Somali community in Minnesota. In order to design effective behavior change interventions to mitigate vaccine hesitancy, we need to understand the role of misinformation in the development or promotion of vaccine hesitancy, as well as the subsequent decision to accept vaccines without delay.

Project Description

This Bass Connections project will study vaccine misinformation and its impact on vaccine hesitancy and uptake in Durham. Specifically, the project team will:

  • Conduct secondary data analysis of the coverage and timeliness of maternal and pediatric vaccines in Durham using the Duke Enterprise Data Unified Content Explorer (DEDUCE) database
  • Collect data on and assess the role of media and web-based information sources in shaping vaccine hesitancy concerns among pregnant women and new parents
  • Retrospectively evaluate the link between vaccine hesitancy and vaccination coverage/timeliness in a cohort of 100 parents who have children (ages 3-6 years) attending Duke Health clinics.

By carrying out these objectives, the team will measure the prevalence and distribution of vaccine hesitancy; elucidate the frequency and type of social media promoting vaccine hesitancy; develop or adapt methods to curate and analyze information sources; and analyze the association between vaccine hesitancy and vaccination uptake in pregnancy and early childhood.

Anticipated Outcomes

Presentation of findings to Duke community and/or members of North Carolina Immunization Advisory Board; abstracts submitted to conferences; manuscript(s) submitted to peer-reviewed journals; preliminary data for grant proposals
