護理師教導新手媽媽關於預防接種。下列何者敘述正確？
A nurse is teaching a new mother about immunization. Which of the following is correct?
- AVaccines cause autism in children疫苗會導致兒童自閉症
- BChildren should not receive vaccines if they have a mild cold兒童若有輕微感冒不應接受疫苗接種
- CVaccines are a form of primary prevention✓ 正解疫苗屬於一級預防措施
- DImmunization is only necessary for children living in cities只有居住在城市的兒童才需要免疫接種
疫苗接種屬於公共衛生的一級預防策略。現代科學已證實疫苗與自閉症無關（該偽科學研究已被撤銷）。疫苗接種率需達到一定門檻才能達成「群體免疫」（Herd immunity），因此不分城鄉均需接種。疫苗僅在有嚴重過敏史或急性重症時為禁忌，輕微感冒且無發燒或嚴重全身症狀者，通常不影響接種，護理師應評估後建議個案按時接種。
Vaccination is a primary-prevention strategy in public health. Modern science has confirmed that vaccines are unrelated to autism (the pseudoscientific study has been retracted). Vaccination coverage must reach a certain threshold to achieve herd immunity, so vaccination is required regardless of whether one lives in an urban or rural area. Vaccines are contraindicated only in cases of a history of severe allergy or acute serious illness; a mild cold without fever or severe systemic symptoms generally does not affect vaccination, and the nurse should assess and recommend that the patient receive the vaccine on schedule.
