This data set is aggregated from three RAND American Life Panel (ALP) surveys that asked respondents their probability of vaccinating for influenza. Their responses were discretized to "Never" (0%), "Always" (100%), or "Sometimes" (any other value). After merging, missing responses were coded as "Missing" and respondents were grouped and counted by all three coded responses. The pre-processed data were kindly contributed by Raffaele Vardavas, and the complete surveys are freely available at the ALP website.
