Note: Adding interactions of own experience with population estimates and with social circle perceptions (each separately for vaccination and flu) in addition to own experiences to overall sample model revealed only a significant interaction of own experience x social circle perceptions for vaccination (β=−.09, B=−.15, se=.07, p<.001; see^a).
