Typhoid vaccine is recommended for military personnel.
These people can receive either:
1 dose of parenteral typhoid vaccine (see also Hepatitis A), or
3 or 4 doses of oral typhoid vaccine; the 4th dose on day 7 is an option — 4 doses may provide better protection than 31,2
The vaccination schedule for oral typhoid vaccine consists of 1 capsule on days 1, 3 and 5 (and day 7 if following a 4-dose schedule) taken 1 hour before food.
