Which factors are important in adults' uptake of a (pre)pandemic influenza vaccine?

Abstract

Since 2008, (pre)pandemic vaccines against H5N1 influenza have been available and pandemic vaccines against new influenza H1N1 are currently produced. In The Netherlands, the vaccination call for seasonal influenza among the recommended groups approximates 70%. These statistics raise the question if adults in Western societies are willing to get a (pre)pandemic influenza vaccination, for example, against avian H5N1 or swine-like H1N1 virus. A questionnaire was performed to determine the predictors of a negative intention to be immunized against pandemic influenza among adults. Demographical, behavioural and organisational determinants were studied. Thirty-four and five percent of the respondents were negatively intended to get a pandemic influenza vaccination in a pre-pandemic or pandemic phase, respectively. On the basis of six behavioural determinants negative intention to get a pandemic influenza vaccination can be predicted correctly in almost 80% of the target group. These determinants should be targeted in pandemic preparedness plans.
