Fig. 3: Count of people vaccinated per site before and after the mobile vaccination programme.

The number of the people vaccinated before and by the end of the study. Data are presented as the mean ± s.e.m. The analysis includes 150 villages. In the control group, on average five people were vaccinated, whereas in treatment villages, this was nine people. Treatment increased the count to 55 people, including 22–23 individuals who were enumerated during the census group, 12–13 people from nearby villages and 11–12 short-term, circular commuters or migrant returnees who were not present on the day of the census and could not be matched to our listing records, as well as individuals whose community of origin was unknown. The intent-to-treat treatment effects estimated using OLS and including randomization block fixed effects and heteroscedasticity-robust standard errors are provided in Extended Data Table 4.
