Interview guide.

Initial information: Short presentation by the interviewer about the project, and to remind the student about his previous participation in the intervention, and that there are discussions in Sweden about HPV vaccination of boys, and that we are therefore interested in the opinion of boys on the subject.

What do you know about HPV? If the boy does not know anything about HPV, then the interviewer will briefly inform the boy about HPV and the HPV vaccine. HPV is a virus, that is spread through sexual contact, and most humans present an HPV infection sometime in their life time. HPV can cause condylomas (genital warts), some HPV-viruses can cause cancer, e.g. in the mouth and neck region, or cervical cancer. Vaccines against HPV protect against the most common HPV-types that cause condylomas and cancer. Only girls are offered HPV vaccination within the school based vaccination program.

What do you think about the fact that the Public Health Agency in Sweden is considering offering HPV-vaccination also to boys?

Would you want to be vaccinated if you were offered HPV vaccination free of charge? If yes, where would you like to be vaccinated?
