By combining game-theoretical models with 2014 survey data from 1,015 parents of children aged 10 years or younger, researchers found that concern for others--or prosocial behavior--was a key driver of polio vaccination in Israel during a polio resurgence in 2013, and was more likely to influence vaccination behavior than self-interest; understanding the vaccination campaign's prosocial nature also influenced vaccination behavior, suggesting the importance of communicating health initiatives to improve outcomes.
