Abstract
We intend to conduct a large in-person survey in rural India to understand the determinants of vaccine hesitancy amongst a primarily unvaccinated sample. Our study will be conducted in Uttar Pradesh and Bihar, with an exclusive focus on data collection from rural areas. Our survey will empirically estimate demand for the vaccine, the determinants of this demand or the lack thereof, and hurdles due to supply-side issues. We will also collect information about knowledge related to COVID-19 and COVID-19 vaccines, adherence to COVID-19 protective measures, media consumption and demographics to serve as covariates in our analysis. In addition to the survey, we also intend to test behaviourally informed communications interventions that we hypothesise could improve vaccine agency amongst our sample. Our sample size will be about 6000 respondents and roughly representative of the rural population of each state.

Experimental Design

Experimental Design
We plan to conduct the survey using the proportional sampling method (based on the 2011 Census) in 20 districts of Uttar Pradesh and 12 districts of Bihar. Within these districts, eight villages will be randomly selected for data collection. Each of these villages is sampled entirely, ensuring proportionate sampling. Participants are first screened on vaccination status. All unvaccinated participants will proceed to the survey, and 10% of participants with one dose and 10% of participants with two doses will complete the survey.
Experimental Design Details
Randomization Method
The recruitment of the participants for the survey does not include randomisation. All unvaccinated participants and 10% of participants with one dose and two vaccination doses pass the screening and complete the entire survey. For the Intervention videos, the participants are randomly assigned to one of 3 arms (vaccinated participants) or one of 7 arms (unvaccinated participants).

Experiment Characteristics

Sample size: planned number of clusters
6000 individuals
Sample size: planned number of observations
6000 individuals
Sample size (or number of clusters) by treatment arms
680 per treatment arm
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
We intend to recruit around 6,000 subjects for the study, which allows us to calculate sample estimates for vaccine hesitancy outcomes for the ~247 million rural population of UP and Bihar with a 99% confidence interval and margin of error of about 1.7%.
