破傷風 (破傷風疫苗)
​Tetanus

破傷風是一個全球性健康的問題。疾病通常發生於一些未曾接受過破傷風疫苗、或預防注射不足的人士。在發展中的國家，大部分的個案發生在嬰兒和幼童的身上。

幼兒必須在出生後 2、4 及 6 個月接受基本的預防注射。再在 15-18 個月、6 歲及 12 歲接受加強劑。若兒童在 7 歲以上始接受預防注射，可選擇給予二合一疫苗(Td)，即包括破傷風疫苗和減量的白喉疫苗，通常會注射三劑破傷風連白喉疫苗，首兩劑相隔 4 至 8 週，第三劑在第二劑後 6 至 12 個月內注射。若於接受基本注射或加強劑後已超過 10 年者，必須要再接受 Td 加強劑。
一般到有風險地區(如東南亞地區、非洲國家)旅遊的人士應接受基本或加強劑的注射。需要經常到此等地區旅遊的人士，建議每隔 10 年接受一次加強劑。

Tetanus is a global health problem. The disease occurs almost exclusively in persons who are non- immunised or inadequately immunised. In developing countries, most of the reported cases occur in infants and young children.

For primary vaccination, children should receive the toxoid at 2, 4, and 6 months of age. Booster doses are also given at 15-18 months, 6 years and 12 years. For primary immunisation of persons above 7 years of age, tetanus vaccine can be given together with a reduced concentration of diphtheria (Td).

Usually, three doses of the formulation of tetanus-diphtheria toxoid are used. The first two doses are given 4 to 8 weeks apart and the third dose 6 to 12 months after the second. A Td booster should be used whenever 10 or more years have elapsed since completion of a primary series or the last booster dose.

Primary or booster doses are recommended for travellers to areas with risk (such as East Asia, African countries). For those who frequently travel to such areas, a ten-yearly booster dose is recommended.
