Summary of simulation results of partially vaccinated populations, assuming an leaky vaccine. Average estimates and intervals extending from the 2.5th and 97.5th percentile of estimates across simulations of (A) ${\alpha }_{\text{AR}}$, (B) ${\alpha }_{\text{EN}}$, and (C) $\varphi$ for the fully observed all-or-none and leaky models, the ecological vaccine model, and the epidemic-endemic model. Red horizontal lines denote the true parameter values. A, $\widehat{{\alpha }_{\text{AR}}}\text{;}$ B, $\widehat{{\alpha }_{\text{EN}}}\text{;}$ C, $\widehat{\varphi }$
