護理師準備為一位 11 歲兒童接種人類乳突病毒 (HPV) 疫苗。護理師應向家長提供下列哪項資訊？
A nurse is preparing to administer the Human Papillomavirus (HPV) vaccine to an 11-year-old child. Which information should the nurse provide to the parent?
- AIf the child gets the vaccine now, they will never need a Pap test in the future如果兒童現在接種疫苗，未來就不需要做子宮頸抹片檢查
- BThe vaccine is most effective when given before the onset of sexual activity✓ 正解在性行為開始前接種疫苗效果最佳
- CThe vaccine is only necessary for girls to prevent cervical cancer只有女孩需要接種疫苗以預防子宮頸癌
- DA total of four doses is required if the series is started before age 15若在 15 歲前開始接種系列，總共需要接種四劑
HPV 疫苗是健康促進中預防癌症的重要介入。核心概念是「預防性接種」。疫苗在未接觸病毒（即發生性行為）前接種效果最顯著。針對 11-12 歲的兒童（不分男女），免疫反應最強。選項 C 錯誤，因為男孩也應接種以預防口咽癌、肛門癌及生殖器疣。選項 A 是危險的誤導，疫苗涵蓋了高風險病毒株但非全部，受測女性未來仍需定期進行子宮頸抹片（Pap test）篩檢。選項 D 錯誤，若在 15 歲前開始接種，標準時程僅需兩劑（間隔 6-12 個月），而非四劑。臨床思路上，護理師應強調疫苗的癌症預防效益，並釐清其與性行為的關聯是基於免疫學時機而非道德判斷。
HPV vaccine produces the strongest immune response when given at 11-12 years of age, before potential exposure to the virus through sexual activity. (C) is wrong because boys are also recommended to receive HPV vaccine to prevent oropharyngeal, anal, and penile cancers and genital warts. (A) is wrong because the vaccine does not cover all oncogenic types, so cervical screening (Pap/HPV co-testing) is still needed. (D) is wrong because per CDC, the schedule before age 15 is TWO doses (0 and 6-12 months); three doses are used only for those starting at 15 or older or who are immunocompromised.
美國 CDC 將 HPV 疫苗列為青少年常規建議疫苗，並由護理師主導接種教育與追蹤。台灣近年來亦推動國中女生公費接種，但對於男生的接種推廣主要還是在自費市場，護理師在衛教時需注意不同性別的政策差異。
