  1. Notes: Self-reported risk is the answer to “Are you generally a person who is fully prepared to take risks or do you try to avoid taking risks? Please choose a value on the scale”, where value 1 means ‘not at all willing to take risks’ and the value 10 means ‘very willing to take risks’. Altruism is the answer to “How willing are you to give to good causes without expecting anything in return?”, where 1 is very unwilling to do so and 10 is very willing to do so. Flu effective? is a 5-point Likert answer to “How effective do you think the flu vaccine is?”, where 1 is very ineffective, 5 is very effective. Flu safe is a 5-point Likert answer to “How likely do you think you are to get a bad reaction from the flu vaccine?”, where 1 is very likely, 5 is very unlikely. Vaccinated previously is equal to 1 if the respondent has gotten a flu vaccine in the past, 0 otherwise
