How long does it take for typhoid vaccine to work?

Answer 1

It takes one week for the vaccine to be effective. You can still protect yourself against Typhoid even without the vaccination. Take precautions with food and drinks while in an effected area: (From the Centers for Disease Control and Prevention) "Boil it, cook it, peel it, or forget it" If you drink water, buy it bottled or bring it to a rolling boil for 1 minute before you drink it. Bottled carbonated water is safer than uncarbonated water. Ask for drinks without ice unless the ice is made from bottled or boiled water. Avoid popsicles and flavored ices that may have been made with contaminated water. Eat foods that have been thoroughly cooked and that are still hot and steaming. Avoid raw vegetables and fruits that cannot be peeled. Vegetables like lettuce are easily contaminated and are very hard to wash well. When you eat raw fruit or vegetables that can be peeled, peel them yourself. (Wash your hands with soap first.) Do not eat the peelings. Avoid foods and beverages from street vendors. It is difficult for food to be kept clean on the street, and many travelers get sick from food bought from street vendors.

Answer 2

Your protection starts by two weeks, more so by three weeks. You get the most of the effect of vaccine by four weeks. Typhoid vaccine does give you total protection. you need to fallow the precautions for sanitation and hygiene.
