偒寒 (傷寒疫苗)
Typhoid (Typhoid vaccine)

​

兩歲以上人士可以接種傷寒疫苗。建議受接種疫苗的人士包括一些在工作上會接觸到傷寒病菌的人士、到疫區旅行，特別是於高危地區(如東南亞地區)的旅遊人士。
免疫能力於接種後 14 天才產生，故旅遊者前往高危地區前需要預備足夠的時間接種。
接種後的免疫能力最少可維持二年。有需要的人士可接種加強劑。

Typhoid vaccine can be given to persons two years of age and older. Vaccination is recommended to those subject to unusual exposure to typhoid from occupation, those travelling to endemic areas (such as East Asia).

The vaccine becomes effective about 14 days after the injection. Travellers should allow adequate time for vaccination before departure to high risk areas.

Minimum duration of protection is at least two years. Booster doses are desirable for those at
continuous risk of infection.
