受到全球化的影響，傳染病更容易隨著人口的移動跨國界傳播，推廣旅遊醫學概念、宣導旅客旅 遊前接受必要的預防接種更顯得刻不容緩。旅遊相關的預防接種，其中包括：（1)例行性接種：指我國幼 兒及成人常規預防接種項目，如卡介苗、B型肝炎疫苗、日本腦炎疫苗、麻疹/德國麻疹/腮腺炎混合疫苗、 白喉/破傷風/百日咳混合疫苗等；（2)必須性接種：部分國家要求旅客必須提出特定疫苗接種證明方允許入 境，如黃熱病疫苗、流行性腦脊髓膜炎疫苗及小兒麻痺疫苗；（3)建議性接種：非強制要求，但評估當地 流行情況及個人風險後，建議旅客接種的疫苗。建議國人出國旅遊前應預先瞭解旅遊當地流行的傳染病， 並提前4-8週至國内26家旅遊醫學門診接受評估。
