Official title

Effectiveness of Interactive Voice Response (IVR) for COVID-19 Vaccination Training of Frontline Health Workers: Experimental Evidence From the Democratic Republic of the Congo

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study seeks to evaluate the effectiveness of a remote training course delivered via interactive voice response (IVR) to the mobile phones of frontline providers in the Democratic Republic of the Congo (DRC) during the COVID-19 pandemic. The randomized trial will examine the impact of the training on health workers' knowledge, beliefs and intended behaviors related to COVID-19 vaccines and vaccine administration. Potential enrollees will be consented first, after which the participants assigned to the treatment group will be invited to participate in the training over a one month period, while the control group will receive the intervention following a month delay, which will allow for the comparison of knowledge and beliefs with a group that is controlled for bias introduced by time. We hypothesize that the training will lead to increased knowledge about vaccines, lower vaccine hesitancy, and increased preparedness to administer vaccines among trained health workers.
