The mechanism for vaccine uptake as a function of Trust and Consumption in Official and Unofficial sources. From left to right: (a) OLS Regression of Trust-Official Source as the dependent variable, Consumption-Official Source and demographics as independent variables; (b) Probit regression of Vaccination Status as the dependent variable, and Trust-Official Source, Trust Unofficial Source, and demographics as independent variables; (c) OLS regression of Trust-Unofficial Source as the dependent variable, Consumption-Unofficial Source and demographics as independent variables.

† OLS Regressions with Trust—Official Source as a dependent variable and Consumption—Official Source as an independent variable as well as other demographic variables. ‡ OLS Regressions with Trust—Unofficial Source as a dependent variable and Consumption—Unofficial Source as an independent variable as well as other demographic variables. ^ Probit Regressions with Vaccination Uptake (1 vaccinated, 0 not vaccinated) as dependent variable, and Trust—Official/Unofficial Sources as independent variables as well as other demographic variables. From regression analyses indicated, significant p-values are denoted by * p < 0.10; ** p < 0.05; *** p < 0.01. 1 The coefficient for Trust—Official Source (0.532) equals to an average 20.68% increase probability of vaccination per unit of trust using the marginal effect of Probit regression. Similarly, the coefficient for Trust—Unofficial Source (−0.321) equals to an average 12.49% decrease probability of vaccination per unit of trust using the marginal effect of Probit regression.
