Cervical cancer is the third most common cancer affecting women worldwide and it is an important cause of death, especially in developing countries. Cervical cancer is caused by human papillomavirus (HPV) and can be prevented by HPV vaccine. The challenge is to expand vaccine availability to countries where it is most needed. In 2008 Peru's Ministry of Health implemented a demonstration project involving 5(th) grade girls in primary schools in the Piura region. We designed and conducted a qualitative study of the decision-making process among parents of girls, and developed a conceptual model describing the process of HPV vaccine acceptance.
We found a nonlinear HPV decision-making process that evolved over time. Initially, the vaccine's newness, the requirement of written consent, and provision of information were important. If information was sufficient and provided by credible sources, many parents accepted the vaccine. Later, after obtaining additional information from teachers, health personnel, and other trusted sources, more parents accepted vaccination. An understanding of the issues surrounding the vaccine developed, parents overcome fears and rumors, and engaged in family negotiations-including hearing the girl's voice in the decision-making process. The concept of prevention (cancer as danger, future health, and trust in vaccines) combined with pragmatic factors (no cost, available at school) and the credibility of the offer (information in the media, recommendation of respected authority figure) were central to motivations that led parents to decide to vaccinate their daughters. A lack of confidence in the health system was the primary inhibitor of vaccine acceptance.
Health personnel and teachers are credible sources of information and can provide important support to HPV vaccination campaigns.
宫颈癌是全球影响女性的第三大常见癌症,是一个重要的死亡原因,尤其是在发展中国家。宫颈癌由人乳头瘤病毒(HPV)引起,可通过HPV疫苗预防。挑战在于将疫苗供应扩大到最需要的国家。2008年,秘鲁卫生部在皮斯科地区的小学实施了一项涉及五年级女生的示范项目。我们设计并开展了一项关于女童家长决策过程的定性研究,并建立了一个描述HPV疫苗接受过程的概念模型。
我们发现HPV决策过程是非线性的,且随时间演变。最初,疫苗的新颖性、书面同意的要求以及信息提供很重要。如果信息充分且来源可靠,许多家长会接受疫苗。后来,在从教师、卫生人员和其他可靠来源获得更多信息后,更多家长接受了疫苗接种。随着对围绕疫苗问题的理解逐渐形成,家长克服了恐惧和谣言,并进行了家庭协商,包括在决策过程中听取女童的意见。预防概念(将癌症视为危险、未来健康以及对疫苗的信任)与务实因素(免费、在学校可获得)以及提议的可信度(媒体信息、受尊敬权威人士的推荐)是促使家长决定为女儿接种疫苗的核心动机。对卫生系统缺乏信心是疫苗接受度的主要阻碍因素。
卫生人员和教师是可靠的信息来源,可为HPV疫苗接种运动提供重要支持。
