Chapter 12: Prophylactic HPV vaccines: Underlying mechanisms

A semi-qualitative study of attitudes to vaccinating adolescents against human papillomavirus without parental consent

Background

The first vaccine to prevent human papillomavirus (HPV) and cervical cancer has been licensed, and in future, vaccination may be routinely offered to 10–14 year old girls. HPV is a sexually transmitted virus and some parents may refuse consent for vaccination. Under-16s in the UK have a right to confidential sexual health care without parental consent. We investigated parents' views on making available HPV vaccination to adolescent minors at sexual health clinics without parental consent.

Methods

This was a semi-qualitative analysis of views of parents of 11–12 year old school children collected as part of a population-based survey of parental attitudes to HPV vaccination in Manchester. Parents were firstly asked if they agreed that a well-informed child should be able to request vaccination at a sexual health clinic without parental consent, and secondly, to provide a reason for this answer. Ethical perspectives on adolescent autonomy provided the framework for descriptive analysis.

Results

307 parents answered the question, and of these, 244 (80%) explained their views. Parents with views consistent with support for adolescent autonomy (n = 99) wanted to encourage responsible behaviour, protect children from ill-informed or bigoted parents, and respected confidentiality and individual rights. In contrast, 97 parents insisted on being involved in decision-making. They emphasised adult responsibility for a child's health and guidance, erosion of parental rights, and respect for cultural and moral values. Other parents (n = 48) wanted clearer legal definitions governing parental rights and responsibilities or hoped for joint decision-making. Parents resistant to adolescent autonomy would be less likely to consent to future HPV vaccination, (67%) than parents supporting this principle (89%; p < 0.001).

Conclusion

In the UK, the principle of adolescent autonomy is recognised and logically should include the right to HPV vaccination, but this may concern parents who would otherwise approve vaccination.

Chapter 30: HPV vaccines and screening in the prevention of cervical cancer; conclusions from a 2006 workshop of international experts

The finding that cervical cancer only occurs in women infected with specific, "high-risk" types of the human papillomavirus (HPV) has led to the development of novel, non-cytology-based cervical cancer prevention strategies. We now have sensitive molecular methods for detecting HPV that dramatically improve our ability to detect high-grade cervical cancer precursor lesions. Perhaps more importantly, prophylactic HPV vaccines have been developed that are protective against cervical cancer precursors caused by HPV 16 and 18. In the Spring of 2006, over 100 experts in HPV, cervical cancer screening, and vaccination worked together to define how best to incorporate HPV DNA testing and the HPV vaccines into cervical cancer prevention efforts. In this summary, we summarize the opinions of this expert group on how these advances can be introduced to provide the maximum benefit to women and to reduce the global burden of cervical cancer.
