Artikeln behandlar hur ungdomar fattade sina beslut kring den svininfluensavaccination som erbjöds under 2009-2010. Utgångspunkten är en videodagboksstudie som genomfördes i samband med vaccinationskampanjen. I denna studie dokumenterade sju ungdomar sina tankar och beslut kring svininfluensan och den erbjudna vaccinationen. Resultaten visade att ungdomarnas argumentation utgick ifrån begreppen risk, kunskap och solidaritet. Däremot kunde vad som ansågs vara den stora risken, sjukdomen eller vaccinationen skifta. Risk, kunskap och solidaritet var ofta kopplade till aktörer som ansågs som viktiga i debatten, som media, familj och vänner samt samhället. Artikeln diskuterar betydelsen av att kunna fatta beslut i frågor där kunskap och risker kopplade till fenomenet är otydliga eller osäkra.

This article deals with how adolescents made their decision connected to the swine flu vaccination which was offered during 2009-2010. The starting point is a video diary study which was conducted during the vaccination campaign. In this study, seven adolescents documented their thoughts and decisions connected to the swine flu and the offered vaccination. The results demonstrated that the adolescents’ argumentation was based on the concepts risk, knowledge and solidarity. However, what was seen as the large risk, the disease or the vaccination differed. Risk, knowledge and solidarity were often connected to actors who were seen as important in the debate, for instance media, family and friends, and the society. This article discusses the importance of decision-making in subjects where knowledge and risks connected to the phenomena are unclear or unsecure.
