Vaccine. 2014 Jun 30;32(31):3936-41. doi: 10.1016/j.vaccine.2014.05.043. Epub 2014 May 20.
HPV vaccination of men who have sex with men (MSM) prior to the commencement of sexual activity would have the maximum impact on preventing HPV and anal cancer in this population. However, knowledge and attitudes towards HPV vaccination among very young MSM have not been previously studied.
Two hundred MSM aged 16 to 20 were recruited via community and other sources. Participants were asked about their knowledge and attitudes towards HPV and HPV vaccination.
Most (80%, 95% confidence interval (CI) 72.2-87.2%) men were not willing to purchase the vaccine because of its cost (AUD$450). However, if the vaccine was offered to MSM free of charge, 86% (95% CI: 80-90%) reported they would be willing to disclose their sexuality to a health care provider in order to obtain the vaccine. Over half (54%, 95%: 47-61%) of men would only be willing to disclose their sexuality to receive the HPV vaccine after their first experience of anal intercourse. The age at first insertive anal intercourse and the age at first receptive anal intercourse were 0.21 (IQR: -2.5 to 3.2) and 0.17 (IQR: -2.9 to 2.7) years earlier than the age that men would be willing to disclose their sexuality to receive the HPV vaccine, respectively. Willingness to receive the vaccine at a younger age was associated with younger age at first insertive anal intercourse.
Overall, very young MSM expressed high acceptance of HPV vaccination. Early, opportunistic vaccination of very young MSM may be feasible in settings where very young MSM have not been vaccinated through universal programs targeting school aged males. However, given HPV infections occur early on, the effectiveness of this approach will be less than vaccination targeting school aged boys.
在开始性行为之前,对男男性行为者(MSM)进行人乳头瘤病毒(HPV)疫苗接种,对预防该人群中的HPV感染和肛门癌将产生最大影响。然而,此前尚未对非常年轻的MSM对HPV疫苗接种的知识和态度进行研究。
通过社区及其他渠道招募了200名年龄在16至20岁之间的MSM。参与者被问及他们对HPV及HPV疫苗接种的知识和态度。
大多数(80%,95%置信区间(CI)72.2 - 87.2%)男性因疫苗成本(450澳元)而不愿购买疫苗。然而,如果向MSM免费提供疫苗,86%(95% CI:80 - 90%)的人表示他们愿意向医疗服务提供者披露自己的性取向以获得疫苗。超过一半(54%,95%:47 - 61%)的男性只有在首次进行肛门性交后才愿意为接种HPV疫苗而披露自己的性取向。首次插入式肛门性交的年龄和首次接受式肛门性交的年龄分别比男性愿意为接种HPV疫苗而披露自己性取向的年龄早0.21(四分位距:-2.5至3.2)岁和0.17(四分位距:-2.9至2.7)岁。在较年轻时愿意接种疫苗与首次插入式肛门性交的年龄较小有关。
总体而言,非常年轻的MSM对HPV疫苗接种表现出较高的接受度。在针对学龄男性的普遍接种计划未涵盖非常年轻的MSM的情况下,对他们进行早期、机会性接种可能是可行的。然而,鉴于HPV感染在早期就会发生,这种方法的效果将低于针对学龄男孩的接种。
