Culturally and Linguistically Appropriate Vaccine Education

Summary

The goal of this clinical trial is to test the effectiveness of culturally tailored social media campaigns and WhatsApp-based vaccine training for healthcare workers in increasing childhood routine and HPV vaccine confidence and uptake in mainly indigenous rural communities in Guatemala.

Main Research Questions:

* Does a culturally tailored social media campaign, deployed via Facebook and geographically targeting randomly assigned communities, increase childhood routine and HPV vaccine confidence and uptake in mainly indigenous rural communities in Guatemala?
* Does WhatsApp-based vaccine training for community healthcare workers increase vaccine uptake in these communities?

Participants in this study will be involved in the following tasks:

Community Healthcare Worker WhatsApp Training: Community healthcare workers will participate in WhatsApp training sessions to enhance their knowledge and skills related to vaccine education and communication.

Pre-Post Surveys: Surveys will be collected from individuals who are caretakers of children under 5 recruited from local health facilities. A total of 600 people will participate in the surveys (200 from each study arm and 200 pre-intervention). Surveys will be conducted in Spanish, K'iche', and Kaqchikel languages to compare vaccination uptake, hesitancy, and barriers/facilitators of vaccination.

Researchers will compare the groups receiving the social media campaign and WhatsApp training to those with no intervention to determine the effects on childhood routine and HPV vaccine confidence and uptake in indigenous rural communities in Guatemala.

Conditions

• Vaccine Hesitancy

Interventions

BEHAVIORAL

Social media interventions for vaccine uptake

Culturally Tailored Social Media Campaign: 4 communities receive a culturally tailored social media campaign via Facebook, focusing on geographical targeting. Content aligns with indigenous cultural norms and values, featuring educational materials, testimonials, and messaging addressing vaccine misconceptions on childhood routine and HPV vaccinations' importance and safety. WhatsApp-Based Vaccine Training for CHW: 4 communities receive both the culturally tailored social media campaign and WhatsApp-based vaccine training for CHWs. Interactive training allows CHWs to engage in discussions, seek guidance, and enhance their ability to communicate effectively. This component targets vaccine hesitancy and boosts vaccine uptake rates.
